Stainless steel pipe fittings are very commonly used in construction. According to the connection method of stainless steel pipes, they are divided into four types: socket pipe, threaded pipe, flange pipe and welded pipe. Stainless steel pipe is also a kind of pipe, made of stainless steel material, so it is called stainless steel pipe. Stainless steel is a very good material, and stainless steel pipes also have outstanding advantages among various pipe fittings. Stainless steel pipes include stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel special-shaped pipes, stainless steel caps, etc. According to the fastening method, it is divided into sleeve type stainless steel pipe, threaded stainless steel pipe, flange stainless steel pipe and welding.

Stainless steel pipes are widely used in life, so how are stainless steel pipes produced? Let's learn about the production process of these stainless steel tubes.

1. Forging method

Use a die forging machine to extrude the end or part of the tube to reduce the outer diameter. Commonly used die forging machines include rotary type, connecting rod type and roller type.

2. Roller method

Place the core in the tube of the stainless steel tube. Press the outside with a roller to process the round edge.

3. Stamping method

Use a punch with a tapered core to expand the pipe end to the required size and shape.

4. Bending method

Three methods are commonly used. One is the stretching method and the other is the extrusion method. The third roll method, 3-4 rolls, two fixed rolls. An adjusting roller adjusts the distance of the fixed roller, and the product tube is bent.

5. Rolling method

Generally, the mandrel is not used, which is suitable for the inner round edge of thick-walled pipe.

6. Roller expansion method

Put the rubber in the tube and compress the upper part with a punch to protrude the forming tube. Another method is hydroforming, filling the center of the tube with liquid. Drum the tube into the desired shape under the pressure of the liquid, and most of the production of bellows uses this method.

Having said so much, stainless steel pipe fittings are a very good pipe material. Let’s take a look at the advantages of stainless steel pipe fittings!

1. Easy to clean

It is easy to clean the surface dirt, no metal detergent is needed, and some chemicals will make the surface of the stainless steel plate black. In addition, handprints, dust, and delicate touch, have a very strong anti-fingerprint and anti-fouling effect.

2. Good coating performance

The stability of stainless steel is very good, and the hardness of such stainless steel is high, and it is not easy to peel, powder and yellow.

3. Beautiful appearance

It has a strong appearance and texture, with oily moisture and soft hand feeling. The transparent coating maintains the original metallic texture of the pipe.

4. Excellent anti-rust performance

Stainless steel pipe fittings have excellent anti-rust performance. By forming a protective film on the metal surface, it can effectively prevent the inside of the metal from corroding from the outside. Significantly extend the life of stainless steel pipes.
