Advantages of 304 stainless steel welded pipe

With the development of industry and technology, stainless steel welded pipes have been popularized in all walks of life, and the number of users using 304 stainless steel welded pipes is also gradually growing. What are the advantages of 304 stainless steel welded pipe? Today I have listed 3 main advantages to share with you.

1. What is 304 stainless steel welded pipe?

304 stainless steel welded pipe is a high-strength, corrosion-resistant pipe. It has a smooth surface, compact structure, good corrosion resistance and wear resistance, can resist the erosion of various corrosive media, and has good heat resistance and Impact resistance, can resist the erosion of high temperature and impact.

304 stainless steel welded pipe has a wide range of applications. It can be used in petroleum, chemical, electric power, metallurgy, heat, hot water, air conditioning, gas, water treatment and other industries, as well as in automobiles, ships, aircraft, machinery manufacturing and other industries.

2.Advantages of 304 stainless steel welded pipe

(1) Corrosion resistance

Stainless steel pipes are not always rust-proof, and the rust-proof properties of high-quality materials will be greatly reduced, just like 304 stainless steel welded pipes, which are universal stainless steel materials and have better rust-proof properties than 200 series stainless steel materials, and their high-temperature resistance is also good. 304 stainless steel has excellent corrosion resistance and good resistance to intergranular corrosion. For oxidizing acids, experiments have found that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration of ≤65% below the boiling point. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.

(2)Welding performance

304 stainless steel welded pipe is usually made of stainless steel plates or steel strips, which are rolled and formed by a machine unit and a mold, and then welded. Because it is welded and formed, many users will worry about cracks opening, but this problem has been solved. The inner weld bead is protected by nitrogen, which is more stable and the inner weld bead is more thoroughly protected. Picking up the stainless steel pipe, you can clearly see that the inner weld bead is a white line. The internal welding beads of brands on the market without internal protection are usually rusty red or black wires. Stainless steel welded pipes protected by nitrogen are not prone to cracking and rusting.

3.304 stainless steel welded pipe price

In terms of price, although 304 stainless steel welded pipes are more expensive than 200 series, the performance of 200 series stainless steel cannot be compared with 300 series stainless steel pipes. Compared with 316 stainless steel pipes, the price of 304 stainless steel welded pipes is more acceptable to the public.
