Classification by steel pipe material: Steel pipes can be divided into: carbon steel pipes, alloy steel pipes, stainless steel pipes, etc. Carbon pipes can be divided into ordinary carbon steel pipes and high-quality carbon structural pipes. Alloy tubes can be divided into: low alloy tubes, composite tubes, financial tubes, high-strength tubes, precision alloys (such as Kovar) tubes, and high-temperature…
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 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…
