  • Quality defects of seamless perforated capillary tubes

    Quality defects of seamless perforated capillary tubes

    Steel management properties: normal temperature mechanical properties, high temperature mechanical properties, low temperature properties, corrosion resistance. The physical and chemical properties of pipes mainly depend on the chemical composition of the steel, the organizational structure and the purity of the steel, as well as the heat treatment method of the pipe.

  • What are the ERW pipe making machines?

    What are the ERW pipe making machines?

    The ERW pipe forming unit initially adopted the chain drawing method. Later the United States created roll molding. The structure of the primary roll forming device is a cross arrangement of flat rolls and vertical rolls, and is mainly used to produce small diameter ERW welded pipes. After continuous improvement, the forming arrangement was changed to the form of flat, vertical roller + vertical roller group, the pipe diameter was developed from small diameter to medium diameter, and high-frequency welding was adopted. It is generally called a small and medium-sized roller forming welded pipe unit. Later, it was further developed into the row and roll type.

  • 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:

  • Cast iron pipe vs Carbon steel pipe

    Cast iron pipe vs Carbon steel pipe

    Carbon steel pipes & tubes also called CS pipes, are made of steel ingots or solid round steels through perforation into capillary tubes, which are then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipe plays an important role in my country's steel pipe industry.
