Read MoreSeamless tubes are tubes without seams or welds. Seamless steel tubes are considered to be able to withstand higher pressures, higher temperatures, higher mechanical stress and corrosive atmospheres. 1. Manufacturing Seamless steel tubes are manufactured using a number of different methods. The method used depends on the desired diameter, or ratio of diameter to wall thickness, required for the…

Read MoreAnti-corrosion steel pipes generally refer to the use of special processes to carry out anti-corrosion treatment on ordinary steel pipes (such as seamless pipes, welded pipes), so that the steel pipes have certain anti-corrosion properties. Corrosion ability is generally used for waterproof, anti-rust, anti-acid and alkali, anti-oxidation and other characteristics. Generally speaking, PE anti-corrosion steel pipe refers to polyethylene…
Read MoreCritical components of alloy steel and thick parts must be preheated before welding. The purpose of preheating the spiral steel pipe before welding is as follows: (1) Preheating can slow down the cooling rate after welding, make hydrogen diffuse in the weld metal and escape, and avoid cracking caused by hydrogen. It can also reduce the degree of hardening…
Read MoreCross rolling is a rolling method between longitudinal rolling and cross rolling. The rolling of the rolled piece rotates along its own axis, deforms and advances between two or three rolls whose longitudinal axes intersect (or incline) in the same direction of rotation. Cross rolling is mainly used for piercing and rolling of pipes (such as the production of…
Read MoreThe cross-rolling piercing process is the most widely used in the production of seamless steel pipes, and was invented by the German Mannesmann brothers in 1883. The cross-rolling piercing machine includes two-roll cross-rolling piercing machine and three-roll cross-rolling piercing machine. The capillary quality defects produced by cross-rolling and piercing of tube blank mainly include inward fold, outward fold, uneven…
Read MoreSurface processing of seamless tubes (smls) mainly includes: steel tube surface shot peening, overall surface grinding and mechanical processing. Its purpose is to further improve the surface quality or dimensional accuracy of steel tubes. Shot peening on the surface of seamless tube: Shot peening on the surface of steel pipe is to spray iron shot or quartz sand shot…
