How to make the inner steel seamless steel tube Products: seamless steel ingot is made of perforated or solid through the capillary tube of small diameter pipe, and then by the hot-rolled, cold-rolled or cold call is made. Seamless steel pipe wall thickness specifications mm diameter * number indicates. Hot and cold rolled seamless steel pipe points (written) seamless steel categories. High-pressure boiler pipe: mainly used to manufacture high-pressure and more pressure steam boiler tubes with high-quality carbon steel, alloy steel and heat-resistant stainless steel seamless steel tubes, boiler tubes by the party at a high temperature and high pressure work tube oxidation and corrosion will occur 12cr1movg small-diameter pipe at high temperature flue gas and water vapor effects, thus requiring a durable steel with high strength, high oxidation resistance, and good organizational stability, the use of steel are : high-quality carbon steel, structural steel have 20G, 20MnG, 25MnG; alloy steel steel 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB etc; 1Cr18Ni9,1Cr18Ni11Nb rust resistant steel used high-pressure boiler tubes in addition to chemical composition and mechanical properties of small-diameter steel pipe plant, hydrostatic testing done by the root, to be flaring, flattening test. Steel to heat treatment delivery. In addition, finished steel microstructure, grain size, decarburization there are certain requirements. Oil cracking pipe: for oil refinery furnace tubes, heat exchanger tubes and seamless pipes. Common quality carbon steel (10, 20), steel (12CrMo, 15CrMo), heat-resistant steel (12Cr2Mo, 15Cr5Mo), stainless steel (1Cr18Ni9,1Cr18Ni9Ti) manufacturing. In addition to the chemical composition of the steel pipe is proved and a variety of mechanical properties, but also to ensure the water pressure, flattening, flaring and other tests, and the surface quality and non-destructive testing. In the heat pipe delivery status.
