304 304L Stainless Steel Pipe
High Strength with Lightweight Design -- Stainless steel pipes combine excellent bending and torsional strength with a relatively light weight, providing durability and structural reliability while reducing overall material usage.
Superior Corrosion and Heat Resistance -- Manufactured from acid-resistant and heat-resistant steel billets, these pipes offer outstanding resistance to rust, oxidation, and high temperatures, ensuring long-lasting performance in harsh environments.
Wide Industrial and Domestic Applications -- Stainless steel pipes are extensively used across industries such as petroleum, chemical, medical, food, and machinery, and are also favored in furniture and kitchenware production due to their durability and clean appearance.
Diverse Product Range for Specialized Needs -- Available in multiple types—including carbon steel pipes, alloy pipes, oil well pipes, boiler tubes, hydraulic tubes, and marine pipes—stainless steel pipes meet the specific requirements of various industries and applications.
Stainless steel pipe is a long, hollow steel product made from acid-resistant and heat-resistant steel billets. These billets undergo processes such as heating, piercing, sizing, hot rolling, and cutting. The finished pipe offers excellent bending and torsional strength while remaining lightweight.
It is widely applied in industries including petroleum, chemical, medical, food, light industry, and machinery, serving both as pipeline systems and mechanical structural components. In addition, stainless steel pipe is commonly used in furniture and kitchenware due to its durability and clean appearance.
Stainless steel pipes are classified into various types, such as ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, bimetal composite pipes, colored stainless steel pipes, oil well pipes (casing, tubing, drill pipes), line pipes, boiler tubes, mechanical structure tubes, hydraulic prop tubes, gas cylinder tubes, geological pipes, chemical pipes (such as high-pressure fertilizer and petroleum cracking tubes), as well as marine pipes.

Classification
Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetallic composite pipes, plated and coated pipes for saving precious metals and meeting special requirements. . There are many kinds of stainless steel pipes, different uses, different technical requirements and different production methods. The outer diameter of the currently produced steel pipe ranges from 0.1 to 4500mm, and the wall thickness ranges from 0.01 to 250mm. In order to distinguish its characteristics, steel pipes are usually classified as follows.
Ways to produce
Stainless steel pipes are divided into two categories: seamless pipes and welded pipes according to production methods. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes and extruded pipes. Cold-drawn and cold-rolled pipes are the secondary Processing; welded pipes are divided into straight seam welded pipes and spiral welded pipes, etc.
Category of use
According to the application, it can be divided into oil well pipe (casing, oil pipe and drill pipe, etc.), line pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, oil cracking pipe) ) and marine pipes, etc.
Stainless steel pipe is a kind of hollow long round steel. Its scope of application is used as a pipeline for transporting fluids. It is mainly widely used in industrial transportation pipelines such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrumentation, etc., as well as mechanical structural components, etc. . The stainless steel pipe is made of acid-resistant and heat-resistant steel billets, which are heated, perforated, sizing, hot-rolled and cut. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchenware.
