1. CleaningUse solvents and emulsions to clean the surface of the steel to remove oil, grease, dust, smoothing agent, and similar organic matter, but it cannot remove the rust, oxide scale, welding flux, etc. on the surface of the steel, so it is only used as an auxiliary in the defense homework. Th
Precision stainless steel pipe fittings, also known as stainless steel precision pipe fittings, are also called precision pipes. In the process of manufacturing, precision stainless steel pipe fittings are much more accurate than ordinary stainless steel pipes in terms of the smoothness of the appea
Ministers were tonight accused of failing to back Britain's steel industry after figures showed tens of millions of pounds of foreign metal was bought for major Government projects. Whitehall departments spent £23million on imported steel, according to research by the GMB union. It analysed official
Japan’s steel exports fell by 18.9% on year to about 2.47 million tonnes in September, or the fifth month posting an on-year decline in the aspect, mainly because of lower steel output in general and thus limited supply from the Japanese mills to the overseas market, Mysteel Global understood from t
A. During the forming process, the steel plate deforms evenly, the residual stress is small, and the surface does not produce scratches. The processed spiral steel pipe has greater flexibility in the size and specification range of diameter and wall thickness, especially in the production of high-gr
How the spiral steel pipe is sawn offAfter a series of treatments such as forming, welding, and cooling, the spiral steel pipe still needs to be sawed. In this link, the length of the technical spare ruler directly affects the quality and sales of the finished welded pipe, so the length of the spare
Slag inclusion in welded steel pipes is the slag remaining inside the weld. From theoretical analysis, the main reasons for slag inclusion in submerged arc automatic welding are as follows: ①There are many inclusions in the raw materials (including base metal, welding wire, and flux); ②The cleaning
1. Regardless of whether the straight seam steel pipe is rotated or fixed The cutting nozzle should be kept perpendicular to the surface of the straight seam steel pipe. After the cutting is completed, the cutting nozzle is gradually tilted forward at an angle of 70°-80° with the tangent line of the
Oil rose to its highest in nearly a week amid a weaker dollar and signs of improving demand in China and India. Crude futures gained 2.1% in New York, while the Bloomberg Dollar Spot Index slipped as much as 0.3%, raising the appeal for commodities priced in the currency. Meanwhile, refinery activit
