China Supplier 201 202 204 Stainless Steel Tube

Short Description:

The Rockwell hardness test of stainless steel pipe is the same as the Brinell hardness test, which is an indentation test method. The difference is that it measures the depth of the indentation. Rockwell hardness test is a widely used method at present, and HRC is second only to Brinell hardness HB in steel pipe standards. Rockwell hardness can be applied to the determination of very soft to very hard metal materials, it makes up for the Brinell method is not, is simpler than the Brinell method, can directly read the hardness value from the dial of the hardness machine. However, due to the small indentation, the hardness value is not as accurate as the Brinell method.

    Main Application

    application

    It has excellent corrosion resistance and high strength, so it is widely used in water systems in various fields. The following are some common application scenarios of stainless steel water pipes:
    1. Household water system: Stainless steel water pipes are widely used in household water systems, such as water supply pipes, hot water pipes and drainage pipes. Its corrosion resistance can ensure that long-term use is not affected by water quality, and the pressure resistance is strong.
    2. Industrial water systems: Many industrial areas need to use water for various production processes, which requires a stable water supply system. Stainless steel water pipes are usually used in industrial water systems to transport industrial wastewater, corrosive liquids, and high temperature and high pressure water, due to their high corrosion resistance and pressure properties.

    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

    Construction projects: Stainless steel water pipes are often used in construction projects for water supply, fire protection systems, HVAC systems, etc., such as buildings, factories, shopping malls and other large buildings
    Food industry: Because stainless steel materials do not contain harmful substances and have good corrosion resistance, stainless steel water pipes are widely used in the food industry. Such as hotels, restaurants, food processing plants and other places of the pipeline system.
    Medical and health field: stainless steel water pipes are widely used in hospitals, laboratories and other places of the water supply system, because of its hygiene and clean, does not contain harmful substances characteristics.

    Process of Production 

    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.
