Application of stainless steel elbow

Stainless steel elbow processing is based on the power of conventional or special stamping devices, so that the sheet material can directly withstand the deformation force and deformation in the mold, so as to obtain the production skills of a certain shape, size and function of commodity parts. Sheets, molds and their equipment are the three elements of stamping. Because the stainless steel elbow pipe has the advantages of inner wall lubrication, small heat medium resistance, acid and alkali resistance, long service life, and convenient installation.

In recent years, it has been widely used in heating systems. As the new generation of heating pipes, the GB stamping elbow is gradually becoming the mainstream commodity in heating stores. Normally, the semi-manufactured products are grouped according to the requirements of the group. The on-site construction is carried out according to the welding grade of the pipeline. It is therefore also called a two-part welded elbow.

Flange connection

Flange connection means that two pipes, fittings or equipment are first fixed on a flange, and flange plates are used between the two flange plates to fasten them together with bolts to complete the connection. Some fittings and fixtures have their own flanges and are also flanged. Flange connection is an important connection method for pipeline construction. The flange connection is easy to use and can withstand greater pressure. In industrial pipes, in the home, the diameter of the pipe is small, and it is low pressure, and the flange connection cannot be seen. If in a boiler room or production site, there are flanged pipes and equipment everywhere.

According to the type of connection flange connection can be divided into: plate type flat welding flange, with welding neck flange, with neck butt welding flange, socket welding flange,threaded flange, flange cover, with neck pair Welding ring loose flange, flat welding ring loose flange, ring groove flange and flange cover, large diameter flat flange, large diameter high neck flange, eight-character blind plate, butt weld ring loose flange, etc. .

Integral Flange installation precautions

Integral flange is mainly used in equipment and pipeline connection, which brings a lot of convenience to equipment and pipeline connection. When installing and using integral flange china, there are many details that need our attention:

1. When the flange is tightened, its tightening force should be kept in the same direction, and the compression of the pad should also be controlled at about one third.

2. The flange should maintain the level and cleanness of the sealing surface during the installation process. If any oil stains or rust spots are found, they must be cleaned to prevent the sealing performance of the flange from being affected.

Stainless Steel Elbow Type

Stainless steel pipe fittings are a new type of pipe connection pipe fittings, also called clamps, which have many advantages. The automatic sprinkler system design specification states that the connection of the system piping should be made with grooved connectors or threaded fasteners and flange connections; in systems with diameters equal to or greater than 100 mm, flanges or grooved connectors should be used in sections. connection.

Variety of stainless steel fittings include 45° elbow, 90° elbow, 90° 3r elbow, four-way, 45° 3r elbow, double socket pipe hoop, single socket pipe clamp, pipe cap, union    , branch socket, etc. Among them, the three links and the four links have equal diameters and different diameters; the double-mouthed pipe hoop also has the same diameter and different diameters, and the double-diameter double-bearing pipe hoop also has concentric and eccentric points.

Five Things to Note When Choosing Stainless Steel Elbow

The stainless steel elbow has good pressure resistance, temperature resistance, pressure resistance, flexibility and heat resistance. Its performance is higher than that of other plastic pipes. Therefore, many people want to buy it, but choosing too much will lead to uncertainty. Therefore, let's talk about the choices for you.

1, first determine the type, the customer wants a thread-type elbow or socket type elbow;

2, look at the material, stainless steel elbow material is stainless steel;

3, bending angle of 45 degrees, 90° elbow, 180 degrees, there are 60 degrees, to see what kind of you want;

4. Look at the caliber and wall thickness of stainless steel elbows, because this directly affects the weight of the elbow;

5, finally you can see the packaging, if the customer has any packaging requirements.

The purpose of 90°reducing elbow

Connecting two tubes with different diameters, making the tube make a 90° turn while reducing the diameter. The production process used was produced using the entire elbow sliver tapering process. The role of the 90°reducing elbow is to change the diameter of the pipe when making a 90-degree turn. The same effect as the size of the head, but the size of the head can not be used for steering. The price is about twice as high as the equal elbow. In some construction sites, this product was replaced with an elbow and a size head welded together. Its material is carbon steel, stainless steel, alloy steel, PVC, cast steel and so on. The most common standards are GB/T12459-2005 and GB/T13401-2005.
