According to the characteristics of industrial non-destructive testing, in order to realize the automatic control of the testing system, most of the eddy current testing of seamless tubes below 180mm in steel pipe enterprises adopts the traditional passing-through coil testing method. For seamless steel tubes over 180mm, if the traditional passing-through eddy current method is used for testing, there…
Read MoreNon-destructive testing refers to the inspection methods used to inspect the internal or surface defects of the material, or to determine some physical quantities, properties, and organizational states of the material without destroying the original state and chemical properties of the material to be tested. There are four commonly used non-destructive testing methods for seamless tubes: 1. X-ray inspection…
Read MoreSeamless tube is a steel pipe that is perforated from a whole round steel and has no welds on the surface. According to the production method, seamless tubes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel tubes, extruded seamless steel tubes, and pipe jacking. Seamless steel pipes are mainly used as petroleum…
Read MoreThere are two types of galvanizing methods for seamless tubes: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing includes wet method, dry method, lead-zinc method, redox method, etc. The main difference between different hot-dip galvanizing methods is what method is used to activate the surface of the pipe body after acid dip cleaning of the steel pipe to improve the quality…

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…
