Read MoreSelection criteria for high frequency welded pipe (ERW) welding consumables Classification of welding rods: (1) Classification by slag properties Welding electrodes can be divided into two categories: acid electrodes and alkaline electrodes. The electrode whose slag is mainly acid oxide is called acid electrode. The electrode whose slag is mainly alkaline oxide and calcium fluoride is called alkaline electrode….
Read MoreThe oxide film on the surface of the hot-rolled seamless pipe is thin and high in density, and it is not easy to fall off. Under normal circumstances, the hot-rolled seamless pipe will cause 0.2-0.3mm oxide scale in the heat treatment equipment, and the casting defects in this range will be It can be removed with the oxidation of…
Read MoreSeamless steel pipes are often used as raw materials for ring-shaped metal material parts, which not only saves a lot of complicated technological processes, but also greatly reduces the wear and tear of stainless steel plates in the production process and saves product costs. The basic principle of this kind of production and processing is not difficult to understand….
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 MoreStainless steel welded pipes processing is easy to cause certain changes to the inside or outside of stainless steel welded pipes. Stainless steel welded pipe welding: Before processing and welding stainless steel welded pipes, rust, oil, water, paint, etc. that are harmful to welding should be thoroughly removed, and an electrode suitable for the steel grade should be selected….
