Galvanized steel pipe

Welded steel pipe with hot-dip galvanized or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and prolong the service life. Galvanized pipe has a wide range of uses. In addition to line pipes for conveying water, gas, oil and other general low-pressure fluids, it is also used as oil well pipes and oil pipes in the petroleum industry, especially offshore oilfields, as well as oil heaters and condensation for chemical coking equipment Pipes for coolers, coal-distilled wash oil exchangers, pipe piles for trestle bridges, and pipes for support frames in mine tunnels, etc.

  1. Purpose: Fire-fighting system and production water supply pipeline with pipe diameter less than or equal to 150mm.
  2. Advantages and disadvantages: high strength, convenient interface, large internal pressure, smooth inner surface, good hydraulic conditions; easy to corrode and high cost.
  3. Connection mode: threaded connection, flange connection.
stainless steel pipe
  1. Purpose: To transport pure water and corrosive production sewage.
  2. Advantages and disadvantages: beautiful appearance and corrosion resistance. Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetal composite pipes, plating and coating pipes to save precious metals and meet special requirements. . There are many types of stainless steel pipes, different uses, different technical requirements, and different production methods. The currently produced steel pipes have an outer diameter range of 0.1-4500mm and a wall thickness range of 0.01-250mm. In order to distinguish its characteristics, steel pipes are usually classified as follows.
