How polish the stainless steel elbow?(二)

3.After the 3,320-mesh blinds have been polished, the elbows are waxed and the newcomers are better.

4. Then continue grinding with the hemp wheel. At this time, press the grinding force harder, the harder the better.

5. Remember to clean the wax after you finish using a dust mite.

How polish the stainless steel elbow?(一)

1, when grinding the stainless steel elbow to use 80-segment wheel, black is more easy to use, with red, must be slow, can not use pressure, try to put the grinding machine polished.

2. All of them have been rubbed before they start to re-grind the once-for-320 vane grinding wheel. The 320-mesh wheel must be polished very carefully, otherwise it will leave 80-mesh grinding wheel scratches.

Alloy elbow also need to be polished.

The advantages of the carbon steel elbow production process

(1) carbon steel reducer elbow is suitable for pipeline system in petroleum, natural gas, chemical, hydropower, construction and boiler industries.

(2) blank for the flat or exhibition surface can be curved, so unloading simple, easy to ensure accuracy, easy assembly and welding.

(3) Due to the above two reasons, the manufacturing cycle can be shortened, and the production cost can be greatly reduced. Because it does not require any special equipment, especially for on-site processing of large-scale stainless steel elbow.

(4) The tube blank is not used as a raw material, the cost of the tube making equipment and the mold can be saved, and the carbon steel elbow with a relatively large diameter and a relatively thin wall thickness can be obtained.

Expansion joints classification

Elbow expansion joint is the use of elastic deformation capacity of the body to compensate for an expansion joint. Its advantage is good strength, long life, can be produced at the scene, the disadvantage is the large space, consume more steel and friction resistance. This expansion joint is widely used in various steam pipes and long pipes.

Pay attention to the connecting flange

Flanges improperly installed when connected, eventually there may be leakage problems. In fact, users do not have to worry after this happens, you should carefully check the possible leaks. In general, most of the leaks are located at the interlinked gaps of the flanges, which are often small and therefore not easy to find.

We will share the use of weld neck flange and threaded flange, if you have comments and suggestions, you can also promptly tell me your thoughts.

Weld Neck Flange standard system

There are two main international standards for Weld Neck Flange, that is, the European pipe flange system represented by the German DIN (including the former Soviet Union) and the American pipe flange system represented by the American ANSI pipe flanges. In addition, there are Japanese JIS pipe flanges, but generally only used for public works in petrochemical plants, and has a relatively small international impact. Pipe flange is now introduced in various countries under the following:

(1) The European system pipe flange represented by Germany and the former Soviet Union

(2) American System Pipe Flange Standard, represented by ANSI B16.5 and ANSI B 16.47

(3) British and French pipe flange standards, each with two sets of pipe flange standards.

Details of carbon steel Bend

Carbon steel Bend is to change the direction of the pipe on the carbon steel pipe fittings. Connection is threaded and welded. According to the angle, there are 45° Bend and 90° Bend180° Bend three kinds of the most commonly used, in addition to engineering needs, including 60 ° and other non-normal angle Bend.

Do you know about the flange

Flange is a disc-shaped parts, flanges are used in pairs,which is commonly to see in the Pipe Fitting project.Also there are 15°5D Bend. In plumbing, flanges are mainly used for pipe connections. In the need to connect the pipe, a variety of installation of a flange, low-pressure pipe can be used silk flange, 4 kg or more pressure using the welding flange Pumps and valves,in connection with the pipe, these equipment parts of the device, but also made of the corresponding flange shape, also known as the flange connection. Where in the two planes around the use of bolt connections at the same time closed the connection parts, are generally referred to as "flange"
