The first stainless steel industrial pipe is made by cold drawing process, the price is high.Different material of stainless steel pipe prices also.For example: a diameter of 89 stainless steel pipe specifications, the price of the material 201 is 16 yuan/kg, 304 18 yuan/kg is the price of material, a ton of differ 2000 yuan price.We use the plank to know: to contrast the plank price of 201 stainless steel material price is 10 / kg, 304 material price is 15 yuan/kg, the price difference is very big.Stainless steel pipe welded pipe and seamless pipe, welded pipe is made of stainless steel plate rolling, welding, seamless steel pipe: with cold-drawn tube billet formed directly.Difference: adopt stainless steel plate welding, the cost is low, the price is low, the cold-drawn tube billet prices will be higher.This is why the cause of the stainless steel GuanGui, here, stainless steel pipe industry the main process is drawn.Stainless steel industrial pipe and stainless steel decoration is the biggest difference?1. Appearance, decorative tube special bright appearance after polishing.Industrial tube is the silver after acid pickling.2. The wall: decorative tube wall thin, industrial pipe wall thickness.If industrial tube thickness over a certain thickness, volume with machines circle difficulty is very big, especially 201 material, if only for welded pipe is likely because deformation of deformation and cracking.
