304 stainless steel seamless pipe is a high-quality hollow made of high-quality 304 stainless steel, with excellent corrosion resistance and mechanical properties. Its surface is smooth and seamless, and it can effectively resist corrosion from weak corrosive media such as air, steam, water, and chemically corrosive media such as acid, alkali, and salt, so it is also called stainless acid-resistant steel pipe.Stainless steel seamless pipes are light in weight when the bending and torsional strengths are the same, so they are also widely used in the manufacture of mechanical parts and engineering structures. They are also commonly used in the production of various conventional weapons, gun barrels, shells, etc.
The corrosion resistance of 304 stainless steel seamless pipe mainly depends on its alloy composition, among which chromium is the core element that gives stainless steel corrosion resistance. When the chromium content in steel reaches about 12%, chromium reacts with oxygen in the corrosive medium to form a dense oxide film (self-passivation film) on the surface, which can effectively prevent further corrosion of the matrix. In addition to chromium, 304 stainless steel seamless pipe also contains alloy elements such as nickel, molybdenum, titanium, niobium, copper, and nitrogen to meet the special requirements of material organization and performance in different application scenarios.
1. Seamless steel pipe: Made by hot rolling, cold rolling or cold drawing, it has the characteristics of no welds, high strength, and excellent pressure resistance, suitable for high-pressure and high-precision occasions.
2. Welded steel pipe: Made by welding process, it has low cost and is suitable for general pressure and low environmental requirements.
1. Circular steel pipe: The most common cross-sectional shape, widely used in fluid transportation, mechanical structure and other fields.
2. Special-shaped steel pipe: including square pipes, rectangular pipes, semicircular pipes, hexagonal pipes, equilateral triangle pipes, octagonal pipes, etc., suitable for special structural or decorative needs.
Stainless steel seamless square pipe of size specifications: 5*5mm to 150*150mm, thickness 1.5mm to 50.0mm, commonly used square tube materials are 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S, etc. Stainless steel seamless square tube has the advantages of corrosion resistance and high temperature resistance, suitable for decorative materials, construction projects, pipelines
The wall thickness of 304 stainless steel seamless pipe, the more economical and practical it is. The thinner the wall thickness, the higher the processing cost. Seamless pipes are superior in high pressure, high strength and mechanical structure materials. When the bending and torsional strength are the same, the weight is lighter, so they are also widely used in the manufacture of mechanical parts and engineering structures. They are also commonly used to produce various stainless steel products.

PRODUCTION PROCESS
1. Hot rolling (extruded seamless steel pipe): round tube billet → heating → perforation → three-roller oblique rolling, continuous rolling or extrusion → tube removal → sizing (or reducing diameter) → cooling → straightening → water pressure test (or flaw detection) → marking → storage
2. Cold drawn (rolled) seamless steel pipe: round tube billet → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → billet tube → heat treatment → straightening → water pressure test (flaw detection) → marking → storage.
