According to different production methods, seamless pipes (smls pipe) can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, and extruded pipes.Since seamless pipes are often in high temperature and high pressure conditions when they are used, seamless pipes are mainly used to make superheater tubes, reheater tubes, steam guide tubes, and main steam seamless tubes for high pressure…
Read More3PE anticorrosive steel pipe base materials include seamless steel pipe, spiral steel pipe and straight seam steel pipe. Anti-corrosion pipelines can be divided into two categories, lined with anti-corrosion steel pipes and outer-wall anti-corrosion steel pipes. The lining anti-corrosion mainly includes cement mortar-lined anti-corrosion steel pipe, which has more applications and lower cost. The cement mortar-lined anti-corrosion steel pipe…
Read MoreThe control of the wall thickness of seamless steel pipe is a difficult point in the production of steel pipes. The measures to improve the accuracy of the wall thickness in the production mainly include the following aspects: 1. Tube billet heating Heating must be uniform, and rapid temperature rise and fall are prohibited. The temperature rise and fall…
Read More1) Appearance defects such as crack, folding, heavy skin, hair grain, pinhole. Generally magnetic particle testing or soak detection is used. For ferromagnetic material, magnetic powder assay should be adopted preferentially, because it has higher flexibility of detection; for non-ferromagnetic material, such as stainless seamless steel pipe, soak test is used. 2) Steel pipe end defects. When obligate excision…
Read MoreElbows are used to change the direction of the pipe. The bending angles of commonly used elbows are 90 °, 45 ° and 180 °. The 180 ° elbow is also called a U-shaped elbow. There are also elbows with special angles, but the number is very few. 1. Cast iron elbow Malleable cast iron elbow is the most…
Read MoreIn our life, no matter what product is used, some precautions are needed during use. Today I will share with you the points that need to be paid attention to when using seamless steel pipes. The use area of steel pipes is relatively large, and it is indirectly destined to be rigorous in use and cannot be used at…
Read MoreThe hardness test of stainless steel should consider its mechanical properties, which are related to the function and quality of stainless steel deformation, stamping, cutting and other processing. Therefore, mechanical function tests must be performed on all seamless steel pipes. Here, 3PE anti-corrosion steel pipe manufacturers suggest that the mechanical function testing methods be divided into two categories, one…
