Read MoreThe control of the wall thickness of the steel pipe is a difficult point in the production of the steel pipe. The measures to improve the accuracy of the wall thickness of the seamless tube in the production mainly include the following aspects: 1. Tube billet heating The heating should be uniform, and it is forbidden to rapidly increase…
Read MoreWhat are the factors that affect the quality of American Standard seamless tubes? 1. Temperature Temperature is the main factor affecting the quality of American Standard seamless steel tubes. First of all, the uniformity of the heating temperature of the tube blank directly affects the wall thickness uniformity and inner surface quality of the perforated capillary, which in turn…
Read MoreThe basic manufacturing process of thick wall P22 seamless alloy pipe is: melting, blank making, extrusion and annealing heat treatment. (1) Smelting P91 steel has high alloy content. How to complete the alloying of steel in a short time is the key of smelting process. P22 seamless alloy pipe is smelted by 50t power electric arc furnace + 5T…
Read MoreThe impact toughness of ASTM standard seamless tube reflects the resistance of the metal to the external impact load. It is generally expressed by the impact toughness value (ak) and the impact energy (Ak), whose units are J/cm2 and J (joules) respectively. Impact toughness or impact energy test (referred to as “impact test”) is divided into three types: normal…
