Welcome to attent the Tube Fair From 14 to 16 June 2023 and Wish we could meet there, do remember that our booth number is W4E08
  • Black steel pipe grade a vs b

    Black steel pipe grade a vs b

    Black steel pipes are commonly used in various industrial applications, including plumbing, construction, and infrastructure projects. When comparing grade A and grade B black steel pipes, it is important to consider their differences in terms of chemical composition, mechanical properties, and specific applications.
  • ASTM A53 black steel pipe

    ASTM A53 black steel pipe

    ASTM A53 is a carbon steel alloy, used as structural steel or for low-pressure plumbing. The alloy specifications are set by ASTM International, in specification ASTM A53/A53M.A53 pipe comes in three types and two grades, A53 Type F, which is longitudinally furnace butt welded or continuous welded (Grades A and B), A53 Type E, which is longitudinally electric resistance welded (Grades A and B), and A53 Type S, which is seamless pipe, produced by hot working, and possibly cold finishing, the steel (Grades A and B).
  • ERW black steel pipe

    ERW black steel pipe

    ERW black steel pipe is a welded pipe made from black steel pipe through electric resistance welding. High frequency resistance welding is a technique used to join metal pipes and other metal components. It usually uses high-frequency current to heat both ends of the pipe to bring it to the melting temperature and connect them in the molten state. Black steel pipe is a steel pipe that has not been galvanized or painted and is usually used to transport gases and liquids.
  • Life expectancy of black steel pipe

    Life expectancy of black steel pipe

    Black steel pipe is primarily composed of carbon and iron, with trace amounts of other elements such as manganese, sulfur, and phosphorus. Unlike galvanized steel pipe, which is coated with zinc for corrosion resistance, black steel pipe relies on its natural oxide layer for protection.
  • Introduction to the grades of black steel pipes

    Introduction to the grades of black steel pipes

    Black steel pipe is commonly used in a variety of industrial applications, including pipelines, construction and infrastructure projects. When comparing Grade A and Grade B black steel pipe, it is important to consider their differences in chemical composition, mechanical properties and specific applications.
  • API 5L Black Oil / Gas Line Pipe

    API 5L Black Oil / Gas Line Pipe

    API 5L Black Oil/Gas Line Pipe stands out for its exceptional qualities, offering superior advantages in the energy sector. Known for its robust construction and high durability, this steel pipe ensures reliable performance in oil and gas applications. With excellent resistance to corrosion and high-pressure capabilities, it meets stringent industry standards, providing a dependable solution for efficient energy transportation.
  • Black welded steel tube

    Black welded steel tube

    Black welded steel tube refers to a welded pipe with a black surface. The "welded steel tube" indicates a steel pipe welded by steel plates or strips after being curled and formed, usually with a fixed length of 6 meters. The "black steel tube" is steel that is not galvanized and its color is caused by iron oxide on the surface.
  • ASTM A178 ERW steel pipe

    ASTM A178 ERW steel pipe

    ASTM A178 ERW Steel Pipe refers to an Electric Resistance Welded pipe manufactured according to the specifications outlined by the American Society for Testing and Materials (ASTM) under the A178 standard. This standard specifically covers carbon steel tubes that are intended for use as boiler tubes, heat exchanger tubes, or superheater tubes.
  • Acceptance standards for large diameter steel pipes

    Acceptance standards for large diameter steel pipes

    Large-diameter steel pipes (such as spiral welded pipes) are pipe products mainly used to transport liquids, gases, solids and other substances, and are usually made of steel. These pipes are commonly used in construction, petrochemical, industry, water supply, heating and other fields. The following is some relevant information about large diameter welded pipes:
