The versatile advantages of duplex stainless steel, blending strength, corrosion resistance, and cost-effectiveness for diverse industrial applications in this overview.

If there is rust or dirt on the inner surface of stainless steel pipe fittings, you can first use a round steel wire brush and cloth strips tied to thick iron wire or thin steel management rope, then penetrate the pipe and pull it back and forth.

The first is the material defect of 304 stainless steel welded pipe during production. Many materials will deform after heating, and some materials will also deform under high pressure. During the use of this product, it will also be deformed due to various reasons.

There are many surface treatment processes for stainless steel pipes. Depending on the use requirements of the pipe, there are many different surface treatment processes such as wire drawing, frosting, and sandblasting.

Stainless steel pipes are hollow oblong steel materials that are widely used in industrial transportation pipelines and mechanical structural parts such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrumentation, etc. In addition, it has the same bending and torsional strength and is light in weight, so it is also widely used in manufacturing mechanical parts and engineering structures.

The main heat treatment processes for stainless steel pipes include annealing, normalizing, quenching and tempering, etc. How do you understand each of these processes?

In many industrial applications, stainless steel materials have very good corrosion resistance. According to actual application data, in addition to mechanical failure, stainless steel corrosion is mainly reflected in local corrosion, that is, stress corrosion, pitting corrosion, intergranular corrosion, and crevice corrosion. These corrosions are introduced below.

With the continuous advancement of material processing technology, stainless steel pipes are also ushering in new development opportunities. Typical applications include automobile exhaust pipes, fuel pipes, fuel injectors and other automobile components.

Stainless steel welded pipes are mainly used in landscape decoration, light industry, pharmaceuticals, water supply and other industries. They are also used in petrochemical and other industries. They usually use medium and low-pressure pipelines with specifications above Φ159mm. In addition, automobile mufflers can also be made of stainless steel welded pipes. become.

At present, the market competition of stainless steel seamless steel pipes is relatively fierce.

Stainless steel welded steel pipe is also called welded pipe. Most of them are stainless steel pipes made by curling stainless steel strips through equipment and then welding them.

At present, the domestic stainless steel casting processing technology is very popular because this technology is relatively simple and has low technical content.
