WH wishes you a happy Mid-Autumn Festival

As a Forge Fitting Supplier, today we are going to share you one of our  traditional Chinese festivals, which is called Mid-Autumn Festival. 

The Mid-Autumn Festival is a traditional Chinese folk festival that evolved from the autumn rituals of the ancient times. Since then , it has customs of worshiping the moon, enjoying the moon, eating moon cakes, playing lanterns, enjoying osmanthus, drinking osmanthus wine and so on which has been passed down to the today .

Mid-Autumn Festival

Every year, August 15 of the Chinese lunar calendar is the traditional Mid-Autumn Festival. The moon on August 15 is more round and brighter than the full moon in other months. This night, people look up to the jade-like moon in the sky , and naturally expect family reunion      . The wanderer far away from home is also relying on his own thoughts about his hometown and his loved ones. Therefore, the Mid-Autumn Festival is also known as the "Reunion       Festival."

Mid-Autumn Festival

Eating mooncake have become a must custom throughout China for the Mid-Autumn festival, this day people eat mooncakes as a symbol of reunion      . The Mooncakes were originally used as offerings to the moon gods, but later people began to enjoy them as a symbol of family reunion      .On the day , it is customary for Chinese families to get together and eat moon cakes while telling their children the story about Chang E, and the jade rabbit.

Forging processing characteristics of forgings

Forging processing characteristics of forgings

The forging products such as Flange High Quality of the forging factory are plastic deformation through forging processing, which is a processing method of obtaining the blank or parts needed for the size, shape and performance of the forgings by using external force to produce plastic deformation of the raw materials of the forgings. The forging process can eliminate the defects of loose casting state and optimize the microstructure structure of metal in the smelting process, and greatly enhance the performance of forgings in use because the complete metal forging streamline is preserved.

Forging is one of the main methods of blank and part production in mechanical manufacturing, which is often divided into free forging, die forging and so on. Compared with other processing methods, forging has the following characteristics:

1. Flange Manufacturer shares that improve the internal organization and mechanical properties of forgings. Forging blank after forging processing, its organization, the performance is improved and improve, forging processing can remove the inside of the metal ingot casting defects such as blow hole, shrinkage cavity and dendritic crystal, and as a result of the metal plastic deformation and recrystallization, can make the rough grain refinement, get the dense metal organization, so as to improve the mechanical properties of forgings. In the design of parts, the impact resistance of forgings can be improved if the stress direction and fiber structure direction of parts are chosen correctly.

2. High utilization rate of materials. Plastic forming of metal is mainly based on the rearrangement of the relative positions of the metal body tissues, without the need to remove the metal.

3. High productivity. Forging processing is usually carried out by means of press and forging hammer.

4. High accuracy of blank or Flange in China. With advanced technology and equipment, cutting less or no cutting can be achieved.

5. The metal materials used in forging should have good plasticity, so that under the action of external force, can produce plastic deformation without fracture. Among the commonly used metal materials, cast iron is brittle material with poor plasticity and cannot be used for forging. Copper, aluminum and their alloys in steel and non-ferrous metals can be processed under pressure in cold or hot states.

6. It is not suitable for forging with complex shape. Forging is formed in solid state. Compared with casting, the flow of metal is limited, and heating and other technological measures are generally required to achieve. It is difficult to manufacture parts with complex shapes, especially those with complex cavities.

Because forging has the above characteristics, so bearing impact or alternating stress of important parts (such as transmission spindle, gear ring, connecting rod, track wheel, etc.), should be used forging rough processing, so forging processing in machinery manufacturing, mining, light industry, heavy industry and other industries has been widely used.

How to choose stainless steel flange material?

How to choose stainless steel flange material?

Mainly used in food industry and surgical equipment, molybdenum is added to obtain a special structure of corrosion resistance. Compared with 304, it has better resistance to chloride corrosion, so it is also used as "Marine steel". SS316 is commonly used in nuclear fuel recovery facilities. Grade 18/10 stainless steels usually also meet this application level.

In order to save stainless steel material, use the form of welding ring. The sealing surface of this structure must be machined after welding ring and pipe. It is usually hung below the operating pressure of 2.5mpa. Smooth face welding flange, due to poor connection rigidity, poor sealing performance, so it is not suitable to use equipment with high air tightness requirements for toxic and inflammable and explosive media.

The connection plate of this structure is made of carbon steel or stainless steel. If it is made of carbon steel, the surface needs to be nickel-plated. The clamp material is cast aluminum ZL7.

Flange in China

Flange High Quality shall be inspected regularly

Stainless steel flange connection is the two pipes, pipe fittings or equipment, first respectively fixed in a flange, between two flange, plus pad, with bolts fastening together, completed the connection. Some pipe fittings and equipment have their own flange, is also a flange connection. Stainless steel flange with threaded flange and welding flange, it is a kind of disc-shaped parts, most common in pipeline engineering, flange are used in pairs. In pipeline engineering, flanges are mainly used for pipe connection. In the need to connect the pipeline, all kinds of installation of a flange, low-pressure pipeline can use wire flange, 4 kg above the use of welding flange. Low pressure small diameter wire flange, high pressure and low pressure large diameter are used welding flange, different pressure flange thickness and connection bolt diameter and number are different. Stainless steel flange piece will not produce corrosion, pitting corrosion, corrosion or wear, is one of the strongest metal materials used in construction. Due to its excellent corrosion resistance, stainless steel enables structural components to permanently maintain engineering design integrity.

Flange  buy from Flange Manufacturer can not be stored for a long time, should make regular inspection, often on the exposed processing surface must be kept clean, remove dirt, neatly stored in the indoor dryness, do not pile or open storage. Flange ball valve, globe valve, gate valve use, only for full open or closed, do not allow to regulate the flow, so as to avoid erosion of sealing surface, accelerate wear. Flange materials are convenient, simple manufacturing, low cost, widely used; But the rigidity is poor, so it can not be used for supply and demand, flammable, explosive and high vacuum requirements of chemical process piping system and high, extremely harmful occasions. The sealing surface type has plane and protruding surface. Flange structure is simple, small volume, light weight; Close and reliable, the sealing surface material of ball valve is widely used in plastic, good sealing, and has been widely used in vacuum system. Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient; When fully open or fully closed, the sealing surface of the sphere and valve seat is isolated from the medium.

Standard and size of reducing pipe

Standard and size of reducing pipe

The Carbon Steel Reducer is also called the size head, and the different diameter. One of the chemical fittings for the connection between two different diameter pipes. According to the shape, it is divided into two types: concentric big head and eccentric head. The size of the head material includes stainless steel size head (304304l316316l), alloy steel, carbon steel size head, size head material is 20 steel, Q235, Q345, 16Mn and so on.

A reducer supplied by Carbon Steel Reducer Manufacturer, is a type of pipe used for pipe caliber. The forming process usually adopted is a reduction press, a diameter expansion press, or a reduction diameter and a diameter expansion press. For some sizes of different diameter pipes, press forming can also be used.

Reduced diameter / expanded diameter forming

The reduction diameter forming process of the reducer is to put a tube blank having the same diameter as the large end of the large and small heads into a forming mold, and to move the metal along the cavity and shrink and form by pressing in the axial direction of the tube blank. According to the size of the reducer of the reducer, it is divided into one press forming or multiple press forming.

Stamping

In addition to the use of steel pipes as raw materials for the production of large and small heads, the size of the head can also be produced by stamping forming process. The shape of the die used for drawing is designed with reference to the inner surface size of the size head, and the steel sheet after the blanking is drawn and formed by a die.

Before bonding, apply a dry cloth to wipe the socket side and the outside of the socket. The following points should be noted:

1. Control caliber: DIN standard (DN10-DN150), 3A/IDF standard (1/2"-6"), ISO standard (Ф12.7-Ф152.4);

Tee fittings

Tee fittings

The tee such as Carbon Steel Tee is a pipe fitting and a pipe joint. Also known as pipe tee or tee pipe fittings, tee joints, used in the main pipe to branch pipe. The three-way is a chemical pipe fitting with three openings, namely one inlet and two outlets; or two inlets and one outlet, having T-shaped and Y-shaped shapes, with equal-diameter nozzles and different diameter nozzles. Three identical or different pipeline collections. The main function of the tee is to change the direction of the fluid.

Tee joints and copper nuts, elbows, ferrule joints, etc. are common parts that are mainly used for docking with pipe fittings. Generally, they can be seen in the gas or liquid pipeline circulation project. The use of the joint, the tee joint is a type of tee joint used in different industries for the use of very frequent pipe fittings.

Classification of tee joints

1. According to the pipe diameter, there are generally tee equal-diameter, Reducing tee.

2. According to the direction of the branch pipe, there are positive tee and oblique tee.

3. According to the material is divided into carbon steel, alloy steel, stainless steel, copper, pvc and other tees.

4. According to the connection method, there are ordinary tee, threaded tee, card sleeve tee, and socket tee.

Tee joint material and manufacturing method

Because the tee joints are used in different industries, the specifications of the tee joints and the materials used have different requirements. The common materials for making tee joints are: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, pvc, etc. The manufacturing method of the three-way joint is mainly topping, pressing, forging, casting and the like.

At present, tee joint is particularly frequently used in various pipeline connection projects, especially in the plumbing and refrigeration industries, and most of the tee joints are made of copper due to the need of heating and cooling!

Pipe Fittings Classification

The pipe is an important part of the pipeline. It acts to connect the pipe, change direction, take out the branch pipe and close the pipe. The same pipe can sometimes play several roles.

These pipe fittings have internal threaded pipe joints, three-way, externally threaded pipe joints, four-way, reducer pipe, pipe cap, and reducer elbow.

Such steel pipes have been standardized.

Pipes for electric welded steel pipes, seamless steel pipes and non-ferrous metal pipes have not been fully standardized. They are often bent and welded in situ using pipes or steel plates. In order to facilitate the installation of the pipeline, the pipe fittings of the steel pipe have been gradually standardized, and are produced by a special factory. At present, the commonly used pipe fittings are commonly used in the construction of stamping elbows, extrusion tees, top pull welding tees, casting, forging tees, die forging concentric or eccentric reducers, caps and so on. These pipes and pipes are connected by butt welding, so they are also called butt welded pipe fittings.

The flange is a circle of discs connected to the end of the pipe or cylinder and the end of the head. A plurality of bolt holes are evenly distributed on the disc, which is an important part that is often used when the pipe or the container is detachably connected.

The flange can be divided into an integral flange, a neck butt weld flange, a flat weld flange, and a loose flange. The Flange mark consists of four parts: the flange name, the nominal pressure value, the nominal diameter value, and the standard code.
