Stainless steel pipe 304L

304L stainless steel pipe 18Cr-8Ni-low carbon is a low-C 304 steel. Under normal conditions, its corrosion resistance is similar to that of 304 steel, but after welding or stress relief, its resistance to grain boundary corrosion is excellent; In the case of heat treatment, it can also maintain good corrosion resistance, and the operating temperature is -196 ° C ~ 800 ° C. It is used in field open-air machines in chemical, coal and petroleum industries that require high resistance to grain boundary corrosion, heat-resistant parts of building materials and parts with difficult heat treatment.

Household goods (category 1 and 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, molded products), medical appliances, building materials, chemicals, food industry, agriculture, ship parts;

Stainless steel, alloy tool steel (in thousandths of C content), such as: 1Cr18Ni9 one thousandth (ie 0.1%C), stainless C≤0.08% such as 0Cr18Ni9, ultra-low carbon C≤0.03% such as 0Cr17Ni13Mo
Type: tube for heat exchanger, thermosolution treatment, pickling
Performance characteristics: The inner wall of the pipe is smooth, the water resistance is low, and it can withstand the erosion of high water flow rate. After solution treatment, the mechanical properties and anti-corrosion properties of the weld bead and the matrix are basically the same, and the deep processing performance is excellent.
Folding Thin Wall Stainless Steel Tube
Uses: Mainly used for direct drinking water projects, other fluid transportation with higher requirements
Main features: long service life; low failure rate and water leakage rate; good conveying water quality, no harmful objects will be precipitated into the water; the inner wall of the pipe is smooth and smooth, and the water conveying resistance is low; Maintenance is required and the cost is low; it can withstand the erosion of high water flow rate up to 30m/s or more; the open pipe is laid and the appearance is beautiful.
Uses: Milk and food industry, pharmaceutical industry, industries with special inner surface requirements. ?
Process features: inner bead leveling treatment, solution treatment, inner surface electrolytic polishing
Performance characteristics: The inner surface roughness Ra is more than 0.2, there is less residue on the wall, easy to clean, prevent bacterial growth, electrolytic polishing has a passivation effect, and the inner wall has good defense performance.
Testing methods: horizontal and vertical flattening, reverse flattening, hydrostatic test or eddy current flaw detection, mechanical property testing, inner surface roughness testing.

Fluid Tube Stainless Steel Tube
Elaborately manufactured stainless steel inner flat welded pipe, widely used in dairy products, beer, beverages, pharmaceuticals, biology, cosmetics, fine chemicals. Compared with ordinary sanitary steel pipes, its surface finish and inner wall are smooth and flat, and the flexibility of the steel plate is better. Wide, uniform wall thickness, higher precision, no pitting, good quality characteristics.
