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 MoreⅠ. High heat transfer coefficient of stainless steel pipe Stainless steel pipes have a high heat transfer coefficient. The heat transfer performance of stainless steel pipe is realized by its unique ultra-thin-walled steel pipe, which is a thin-walled pipe with continuous tangent between large and small arcs and corrugated inner and outer shapes. The height difference between the wave…
Read MoreIn order to improve the performance of stainless steel pipe (ss pipe), it is often necessary to adopt certain cold working methods, such as cold drawing, cold rolling, cold rolling, cold bending, cold expansion, cold twisting, etc., which can achieve a certain effect and cause certain damage. Cold working is actually like welding, which will inevitably damage the performance…
Read More1) The comprehensive mechanical properties are better than ferritic stainless steel, especially plastic toughness, not as sensitive to brittleness as ferritic stainless steel. 2) In addition to stress corrosion resistance, other local corrosion resistance is superior to ferritic stainless steel. 3) Cold working process performance and cold forming performance are much better than ferritic stainless steel. 4) The welding…
Read More1. Pollution and corrosion resistance Corrosion is the main enemy of metal pipes. The outer surface of steel, iron and concrete pipes is degraded by soil and ultraviolet rays. The inner walls of pipes made of other materials are prone to rust, be damaged by wear or accumulate debris. However, due to the corrosion resistance of stainless steel, this…
