ERW pipe adopts electric resistance welded technology, and the welding quality control in the process is very important. The general method is as follows: 1. Product damage inspection procedures Destruction inspection shall involve inserting a tool or device between the welded part and the part adjacent to the weld until the components are completely separated. The diameter of the…
Read MoreWhat are the processing methods of stainless steel welded pipe? What should be paid attention to in processing? Cold drawing deep processing: it is easy to generate friction heat, so the stainless steel pipe with high pressure resistance and heat resistance shall be formed at the same time. After processing, the oil attached to the surface shall be removed….
Read More(1) Cold-drawn or cold-rolled anticorrosive spiral steel pipes with a wall thickness of not more than 1.5 mm; welded steel pipes with a wall thickness of not more than 1 mm and surface-polished rolled stainless steel pipes shall be packed in strong wooden or iron boxes. (2) Each box should be steel pipes with the same contract number. When…
Read More1. Many people think that stainless steel pipes will not rust, which is a wrong one-sided view. First of all, stainless steel pipe rust resistance and corrosion resistance are conditional. Stainless steel pipes are steel pipes that do not rust in weak corrosive environments such as atmosphere and fresh water, and the chromium content in the steel must be…
Read MoreAnti-corrosion steel pipes are divided into two categories: outer wall anti-corrosion and inner wall anti-corrosion steel pipe： Outer wall anticorrosion classification 1. 3PE anti-corrosion. The three-layer PE anticorrosion of the pipeline refers to the integration of the first layer of epoxy powder, the second layer of adhesive, and the third layer of polyethylene into one body, and is firmly…
Read MoreAlloy steel pipes can be used to transport different substances, mainly including the following: 1. Transportation of solid particles and powders – anti-wear, impact resistance, self lubrication, anti adhesion, sanitation and cleanliness, impact absorption, good silencing effect, good resistance to environmental stress cracking, light weight, which can be applied to various industries, such as anti-wear transportation of solid particles…
Read MoreASTM A234 is Standard Specification for steel pipe fittings includes carbon and alloy steel material for moderate and high temperature services. It covers steel fittings of seamless and welded types. Steel Pipe fittings are applied in pressure pipelines and in pressure vessel fabrications. These fittings material consist of killed steel, forgings, bars, plates, seamless or HFW (fusion welded) pipe…
Read MoreWhat is wrought steel Wrought steel material refers to product forms (forged, rolled, ring rolled, extruded…), while forging is a subset of wrought product form. Difference between wrought steel and forged steel 1.The main difference between wrought and forged steel is strength.Forged steels are tougher than wrought steels as they begin as a casting which is then forged which…
