Stainless steel pipe

Stainless steel pipe is mainly used for three purposes: 1. Stainless steel decorative pipe In fact, it is a stainless steel pipe used for decoration, which is mainly widely used in stainless steel anti-theft windows, stair guardrails, stair handrails, etc. 2. Stainless steel industrial pipe It is divided into seamless pipe and welded pipe. Scope of application: due to the thin stainless steel welded pipe and good surface treatment effect, it is mainly used for architectural decoration products, civil decorative art stainless steel products, etc. The stainless steel industrial pipe has thick wall, uneven surface and strong bearing capacity. It is mainly used to make large size, high strength, high toughness, mechanical systems and other products. 3. Stainless steel product pipe Stainless steel product pipe refers to the stainless steel pipe specially customized by the stainless steel pipe manufacturer because the ordinary stainless steel decorative pipe does not meet its use requirements.

PRODUCT DETAILS

Product Presentation:

Stainless steel pipe is a kind of hollow long round steel, which is mainly widely used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrumentation, etc. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also commonly used as furniture, kitchen utensils, etc.

Use of Stainless steel pipe:

1. The heater is generally used in the oil refining unit; 2. Chemical plant equipment pipeline; 3. Fast cooling cylinder for solid solution used in textile industry; 4. Seamless steel pipe for heat exchanger and condenser. 5. High pressure seamless steel pipe for food (gb-2000) is a high-quality carbon structural steel and alloy steel seamless steel pipe suitable for chemical equipment and pipes with working temperature of - 40~400 ° C and working pressure of 10~30ma. 6. Seamless steel pipes for geological drilling and oil drilling control. 7. Cracking pipe for petrochemical industry is used to transport high-temperature and high-pressure fluid on fertilizer equipment.

Classification Of Stainless Steel Pipes:

● Stainless Steel Seamless Pipe

Stainless steel seamless pipe is a long steel material with a hollow section and no seams around it. The thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the processing cost will increase significantly. It reflects its superiority in terms of high pressure, high strength, and mechanical structural materials.
According to different production methods, it can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, etc.

● Stainless Steel Welded Pipe

Stainless steel welded pipe, referred to as welded pipe, is a steel pipe made of commonly used steel or steel strips after being curled and formed by a unit and a mold. The production process of welded steel pipes is simple, the production efficiency is high, and there are many varieties and specifications, but the general strength is lower than that of seamless steel pipes. Generally, welded steel pipes have high precision, uniform wall thickness, high internal and external brightness (the surface brightness of the steel pipe is determined by the surface grade of the steel plate), and can be arbitrarily cut to length. Therefore, it reflects its economy and aesthetics in high-precision, medium and low-pressure fluid applications.
According to the welding seam form, it is divided into straight seam welded pipe and spiral welded pipe.

● Stainless Steel Square Tubes

Stainless steel square tube is a hollow long steel material. It is called a square tube because its cross section is square. It is widely used in industry as pipelines for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. Of course, it is used more widely in the construction industry, such as stair handrails, window protection, railings, road partitions, etc.
