1. Seamless steel pipes for general purposes are rolled from ordinary carbon structural steel, low alloy structural steel, or alloy structural steel, with the highest yield and mainly used as pipelines or structural parts for conveying fluids. 2. Supply is divided into three categories based on different purposes: a. Supplied according to chemical composition and mechanical properties; b. Supplied according to mechanical properties; c. Supply according to hydraulic test. Steel pipes supplied in categories a and b, if used to withstand liquid pressure, must also undergo hydraulic testing.

Product Description
Product Description
product details
① The main production process of hot-rolled seamless steel pipes (△ main inspection process): preparation and inspection of pipe billets △ → heating of pipe billets → perforation → rolling of pipes → reheating of steel pipes → sizing (reduction) → heat treatment △ → straightening of finished pipes → finishing → inspection △ (non-destructive, physical and chemical, bench inspection) → warehousing
② Cold rolled (drawn) seamless steel pipes Main production process: preparation of billets → acid washing and lubrication → cold rolling (drawing) The production process of general seamless steel pipes can be divided into two types: cold drawing and hot rolling. The production process of cold rolled seamless steel pipes is generally more complex than hot rolling. The pipe blank first needs to undergo three-roll continuous rolling, and after extrusion, it needs to undergo diameter testing. If there are no response cracks on the surface, the circular pipe needs to be cut by a cutting machine, cutting the blank with a length of about one meter. Then enter the annealing process, where acidic liquid is used for pickling. During pickling, attention should be paid to whether there is a large amount of blistering on the surface. If there is a large amount of blistering, it indicates that the quality of the steel pipe does not meet the corresponding standards. The appearance of cold-rolled seamless steel pipes is shorter than that of hot-rolled seamless steel pipes. The wall thickness of cold-rolled seamless steel pipes is generally smaller than that of hot-rolled seamless steel pipes, but the surface looks brighter than thick walled seamless steel pipes, with no too much roughness on the surface and no too many burrs on the diameter. The delivery status of hot-rolled seamless steel pipes is generally after heat treatment in the hot-rolled state. After undergoing quality inspection, hot-rolled seamless steel pipes must undergo strict manual selection by the staff, and the surface must be coated with oil after inspection
