Alloy tubes are divided into structural seamless tubes and high-pressure heat-resistant alloy tubes. Mainly different from the production standard of alloy pipe and its industry, annealing and tempering of alloy pipe changes its mechanical properties and achieves the required processing conditions. Its performance is higher than that of ordinary seamless steel pipes, and its chemical composition contains more Cr,…
Read MoreThe difference between carbon steel seamless tube and stainless steel seamless tube mainly refers to the difference in design rules between carbon steel and stainless steel, which means that the design rules of these two types of steel cannot be used in common. These differences are summarized as follows: Carbon steel 1. Ordinary steel is carbon steel, that is,…
Read MoreThe mechanical properties test methods are mainly divided into two categories: tensile test and hardness test. The tensile test is to make a sample of carbon steel tube, break the sample on a tensile testing machine, and then measure one or several mechanical properties, usually tensile strength, yield strength, elongation after fracture and area shrinkage. Tensile test is the…
Read MoreAccording 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…
