Common steel defects and related terms are introduced by seamless pipe manufacturers as follows: 1. Roundness: the circular section of the rolled material, such as the cross section of round steel and round steel pipe, the degree of diameter difference in each direction 2. Due to unreasonable mold design or manufacture, improper extrusion process, mold and extrusion cylinder, lubrication,…
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 MoreThe application of steel pipes in marine engineering is very common. There are roughly three types of steel pipes in the two major systems of shipbuilding and marine engineering: steel pipes in conventional systems, steel pipes used in construction, and steel pipes for special purposes. Different ships and marine projects have both conventional and special systems. The service life…

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 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…
Read MoreSubmerged arc welding technology is the welding process of SSAW steel pipe and LSAW steel pipe. During the welding process, in addition to insufficient penetration, burn-through and poor formation caused by improper welding process parameters, there will also be pores, slag inclusions, cracks, etc. Defects. This article mainly introduces the main reasons and preventive measures for porosity in submerged…
Read MoreThe surface treatment of seamless pipe is one of the key factors in determining the anti-corrosion life of the pipe. In the practical application of seamless pipe, the surface of seamless pipe is usually descaled in order to prolong its service life. The descaling of seamless pipe is divided into tool descaling and spray descaling. So what should be…
