Seamless stainless steel tubes, also called stainless steel seamless pipe, are made of steel ingots or solid tube billets through perforation to make capillaries, and then hot rolled, cold rolled, or cold drew which with excellent corrosion and high-temperature resistance.

Seamless stainless steel pipe is a long steel with a hollow cross-section and no seam around it. The thicker the wall thickness of the product, the more economical and practical it is, while the thinner the wall thickness, the higher the cost of the processing; the process of the product determines its limited performance. General seamless stainless steel pipe precision is low: uneven wall thickness, low brightness of the tube appearance, high cost of sizing, and the internal and external appearance of the pockmark, black spot is not easy to remove; its detection and shaping must be off-line processing. Therefore, it embodies its superiority in high pressure, high strength, and mechanical structure material.

The specifications of seamless stainless steel pipe are expressed in millimeters of outer diameter * wall thickness.

FAQ

How is seamless stainless steel pipe different from welded pipe?

Seamless stainless steel pipe and welded pipe differ in their manufacturing processes. Seamless pipe is produced by piercing a solid cylindrical billet to form a hollow tube, while welded pipe is created by welding together the edges of a flat or rolled steel plate or strip. The absence of a weld seam in seamless pipe results in a uniform and continuous structure, providing higher strength and better pressure resistance. Additionally, seamless pipe exhibits enhanced corrosion resistance and is often preferred for critical applications that require high reliability and integrity. Welded pipe, on the other hand, offers cost advantages and is commonly used for less demanding applications.

What are the different grades of stainless steel used in seamless pipe manufacturing?

There are several grades of stainless steel used in the manufacturing of seamless pipes, each offering unique properties and suitability for specific applications. Some common grades include:

304/304L: This is the most widely used stainless steel grade, known for its excellent corrosion resistance, high-temperature strength, and versatility.
316/316L: It contains molybdenum, which enhances its corrosion resistance, particularly in chloride environments. It is commonly used in industries such as marine, chemical, and pharmaceutical.
321/321H: This grade offers excellent high-temperature strength and resistance to intergranular corrosion. It is often used in applications involving elevated temperatures, such as heat exchangers and furnace components.
310/310S: It exhibits excellent resistance to high-temperature oxidation and can withstand thermal cycling. It is commonly used in heat treatment equipment and power generation industries.
