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 More1) Can seamless steel tube be galvanized? Seamless steel tube refers to a steel pipe that is perforated from a whole round steel and has no welds on the surface. It is widely used. Ordinary galvanized pipes are generally made of welded pipes. Can seamless steel tubes be galvanized? The answer is To be sure, galvanizing treatment is to…
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 MoreCarbon steel tubes consist of an iron and carbon alloy that is able to be bent into shapes during manufacture without reducing its high tensile strength. It is important to protect the steel surface from corrosion due to the iron ferrite composition that will rust through oxidization from water contact. The pipework that supplies fire sprinkler systems is often…
Read MoreA) What are the two galvanizing processes for square and rectangular tubes? Galvanized square tube, also known as galvanized square tube, is a square tube that has been galvanized. According to different production processes, galvanized square tube can be divided into two types: hot-dip galvanized square tube and cold-galvanized square tube: 1. Hot-dip galvanized square tube It is a…
