Stainless Steel Seamless Pipe (304H 304 316 316L 316H 321 309 310 310S)

Stainless Steel Seamless Pipe (304H 304 316 316L 316H 321 309 310 310S)

Short Description:

201 stainless steel pipe: It is a chromium-nickel-manganese austenitic stainless steel with relatively low magnetism.

410 stainless steel pipe: It belongs to martensite (high-strength chromium steel), has good wear resistance and poor corrosion resistance.

420 stainless steel pipe: “knife grade” martensitic steel, similar to the earliest stainless steel such as Brinell high chromium steel. Also used in surgical knives, which can be made very shiny.

304L stainless steel pipe: As a low-carbon 304 steel, under normal circumstances, its corrosion resistance is similar to that of 304. However, after welding or stress relief, its resistance to intergranular corrosion is excellent, and it can maintain its corrosion resistance without heat treatment. Good corrosion resistance.

    Main Application

    application

    310 stainless steel welded pipe: The main feature is high temperature resistance. It is generally used in boilers and automobile exhaust pipes. Other performance is average.

    1. Ferritic stainless steel. Contains 12% to 30% chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its chloride stress corrosion resistance is better than other types of stainless steel.

    2. Austenitic stainless steel. It contains more than 18% chromium, and also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. It has good comprehensive performance and can withstand corrosion from various media.

    3. Austenitic-ferritic duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steel and has superplasticity.

    4. Martensitic stainless steel. High strength, but poor plasticity and weldability.

    Note:
    1.Free sampling, 100% after-sales quality assurance, Support any payment method;

    Stainless Steel Pipe Surface Finish

    Industrial development changes rapidly, and stainless steel pipes also follow industrial development to meet the development needs of various industries. The following are the wide applications of stainless steel pipes in various industries:

    不锈钢板_05

    Water supply and drainage pipes, irrigation systems
    Water supply and drainage pipeline engineering is for the transportation and distribution industry. Drinking water and collection. Transportation and discharge of industrial wastewater. Domestic sewage and rainwater pipe (channel) system engineering.
    Engineering investment accounts for the majority of total engineering investment. Sprinkler irrigation systems are an important part of agricultural water use. The physical and chemical properties of stainless steel water pipes meet the requirements of modern agricultural water treatment.

    Process of Production 

    There are various connection methods for stainless steel pipes. Common pipe fitting types include compression type, compression type, union type, push type, push thread type, socket welding type, union flange connection, welding type and welding and traditional connection. Combined derived series connection methods. These connection methods have different application scopes according to their different principles, but most of them are easy to install, strong and reliable. The sealing ring or gasket material used for the connection is mostly made of silicone rubber, nitrile rubber and EPDM rubber that meet national standards, which relieves users from worries.

    Packing and Transportation

    1. Plastic sheet packaging
    During transportation of stainless steel pipes, plastic sheets are often used to package the pipes. This packaging method is beneficial to protect the surface of the stainless steel pipe from wear, scratches and contamination, and also plays a role in moisture-proof, dust-proof and anti-corrosion.
    2. Tape packaging
    Tape packaging is an affordable, simple and easy way to package stainless steel pipes, usually using clear or white tape. The use of tape packaging can not only protect the surface of the pipeline, but also strengthen the strength of the pipeline and reduce the possibility of displacement or distortion of the pipeline during transportation.
    3. Wooden pallet packaging
    In the transportation and storage of large stainless steel pipes, wooden pallet packaging is a very practical way. The stainless steel pipes are fixed on the pallet with steel strips, which can provide very good protection and prevent the pipes from being collided, bent, deformed, etc. during transportation.
    4. Carton packaging
    For some smaller stainless steel pipes, carton packaging is a more common way. The advantage of carton packaging is that it is light and easy to transport. In addition to protecting the surface of the pipe, it can also be convenient for storage and management.
    5. Container packaging
    For large-scale stainless steel pipe exports, container packaging is a very common way. Container packaging can ensure that pipelines are transported safely and without accidents at sea, and avoid deviations, collisions, etc. during transportation.
