S25073 stainless steel is a stainless steel material with high strength and high corrosion resistance, composed of gold elements such as chromium, nickel, and molybdenum. Compared with other types of stainless steel, S25073 has the following characteristics:1. High strength: S25073 stainless steel h
1. Location: The storage area should be well-ventilated, dry and protected from the elements. It should also be easily accessible for inspecting, handling, and loading/unloading the pipes.2. Stacking: Pipes should be stacked in a way that prevents deformation or damage. They should be supported even
1. Coatings: Applying protective coatings on the carbon steel pipe's surface can help prevent corrosion. Coatings like epoxy, polyethylene, or fusion bond epoxy (FBE) provide a barrier against moisture and corrosive substances.2. Cathodic Protection: This method involves using a sacrificial anode or
International standards:According to international standards, the allowable deviation value of seamless pipe wall thickness should comply with the following regulations:1. For seamless steel pipes with wall thickness > or = 20mm, the allowable deviation value should be within plus or minus 10%;2. Fo
Seamless tubes, like seamless pipes, are produced without a joint and are known for their high-quality performance in various applications. The ovality of a seamless tube refers to the degree of circularity deviation from a perfect circle. It is an important parameter as it affects the tube's streng
Spiral welded steel pipes are produced by spiral submerged arc welding or double-sided submerged arc welding process. The workshop hoisting specifications for spiral welded steel pipes mainly include the following aspects:1. Lifting equipment: The workshop should be equipped with suitable lifting eq
1. Cutting of large-diameter plastic-coated steel pipes for water transportation. Metal saws should be used to cut steel pipes. Large-diameter steel pipes should be cut with saws. When cutting with entanglement, the rotation speed should not exceed 800r/min; the cross-section of the steel pipe to be
Hot-dip galvanized seamless pipes are generally coated with a layer of zinc on low-carbon steel, and the thickness of the zinc layer is generally 20um. The melting point of zinc is 419°C and the boiling point is about 908°C. During the welding process, zinc melts into a liquid.1. Use indirect fusion
1. Definition of straight seam steel pipe weldsStraight seam steel pipe weld refers to the joint part formed by joining two steel plates together through a welding process. The quality of the weld is directly related to the strength, sealing, and service life of the steel pipe.2. Welding process and
3PE anti-corrosion steel pipe base materials include seamless steel pipes, spiral steel pipes, and straight seam steel pipes. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the oil pipeline industry due to its good corrosion resistance, water vapor permeability res
