2205, 2507 Stainless Steel Pipes

Austenitic stainless steel, featuring excellent high-temperature oxidation resistance, is suitable for continuous exposure to environments up to 2100°F and can also be used intermittently at temperatures as high as 1900°F.

304L Stainless Steel Pipe

We are a manufacturer and supplier of 304L stainless steel pipes, with products suitable for transporting both liquids and gases. These 304L stainless steel welded pipes are manufactured using a cold-forming process, with steel coils as the raw material, and are joined together via automated spiral welding technology. We have made significant advancements in areas such as quality control, inspection, jointing techniques, and surface protective coatings.

347H

347H stainless steel is a niobium/tantalum-stabilized austenitic chromium-nickel stainless steel. By adding niobium and tantalum, this material effectively inhibits the formation of chromium carbides. Since these elements have a stronger affinity for carbon than chromium does, niobium-tantalum carbides preferentially precipitate within the grain interiors rather than accumulating at grain boundaries. As a result, 347H is ideal for applications requiring intermittent heating between 800°F (427°C) and 1650°F (899°C), or in situations where post-weld annealing cannot be performed after welding. Additionally, 347H stainless steel is non-magnetic.

321 Stainless Steel Pipe

Alloy 321 is an austenitic stainless steel containing a higher level of molybdenum, along with the additional element nitrogen. This unique composition makes it particularly effective in enhancing resistance to pitting and crevice corrosion, while also providing outstanding resistance to chemical attack. Its low-carbon content ensures minimal susceptibility to sensitization during welding, while the added nitrogen further boosts the material's overall strength. Moreover, Alloy 321 boasts the highest resistance to aqueous solution corrosion among all standard stainless steels, and it also exhibits superior creep resistance, stress rupture strength, and tensile strength at elevated temperatures.

Stainless Steel 347H Seamless Steel Pipe

We offer a diverse range of pipe products made from various materials and in multiple types, including seamless pipes, ERW pipes, welded pipes, custom-processed pipes, and CDW pipes, among others. Additionally, these pipes come in an array of shapes, such as round, square, and rectangular tubes. SS 347H seamless pipes are available in three standard length options: single random length, double random length, and fixed-length cut-to-size. Typically, our pipes adhere to industry-standard shapes, dimensions, and specifications—but we also provide customized pipe solutions tailored to meet specific customer requirements, whether it’s for unique shapes, sizes, or specialized specifications. Moreover, we can supply pipe materials in different grades based on customer needs. As for the end configurations, we offer a variety of options, including bright ends, beveled ends, and threaded ends, to suit your application.
