How is S235JRH straight seam welded steel pipe manufactured?
The manufacturing method of S235JRH straight seam welded steel pipe is as follows: Steel strip is cold-bent into a cylinder, and then the edges are joined using welding processes such as resistance welding (ERW). After welding, the steel pipe is cut to the required length and may undergo further finishing or testing before being put into use.
What are the main applications of S235JRH straight seam welded steel pipe?
S235JRH straight seam welded steel pipe is widely used in water supply projects, petrochemicals, chemicals, power, agricultural irrigation, urban construction, and other fields. It also plays an important role in liquid transportation, such as water supply and drainage. It is used for gas transportation: natural gas, steam, and liquefied petroleum gas. It is used in structures: pile foundation pipelines, bridges; docks, roads, building structures, etc.
What are the anti-corrosion treatment methods for S235JRH welded straight seam pipe?
Common anti-corrosion treatment methods for S235JRH welded straight seam pipe include hot-dip galvanizing, spraying, and various coating systems.
What is the pressure-bearing performance of S235JRH welded straight seam pipe?
S235JRH welded straight seam pipe is mainly used in structural applications. Its minimum yield strength is 235 MPa, and its tensile strength is typically between 360-510 MPa. Its pressure-bearing performance is suitable for general buildings and load-bearing structures.
What are the heat treatment processes for S235JRH welded straight seam pipe?
Common heat treatment processes for S235JRH welded straight seam pipe include normalizing, annealing, and stress relief to improve its mechanical properties and eliminate residual stress.
