Cold Drawn Steel Tubes

Straight seam welded pipe shot abrasive jet (cast) : in order to achieve the ideal cleaning effect, should according to the appearance of hardness, straight seam welded pipe equipment requirement of original corrosion level, surface roughness, coating types to choose abrasive, such as for single layer, layer or three layer PE coating epoxy, using a mixture of steel shot and steel grit Cold Drawn Steel Tubes grinding are more likely to achieve ideal cleaning effect. Steel pill have the effect of the reinforcement steel surface, and it has steel grit etching on the surface of the steel. Steel shot and steel shot abrasive (usually the hardness of steel shot is 4050 HRC harder to 5060 HRC can be used for all kinds of steel surface, even in the class C and D corrosion of steel surface, cleaning effect is very good also.
Straight seam welded pipe derusting speed: abrasive per unit of time applied to steel tube, the total kinetic energy E and single grain steel pipe derusting abrasive the kinetic energy of the E1 speed depends on the type of abrasive and abrasive emissions. Type: m abrasive jet (left); V abrasive speed; M1 quality of single abrasive particles. M size is associated with abrasive grinding rate, broken rate Cold Drawn Tubes size directly affect the appearance treatment assignment of interest and the cost of cleaning equipment. When the device is fixed, m is constant, y is constant, so E is a constant, but as a result of abrasive, m1 change, therefore, generally should choose the abrasive attrition rate is low, so clear to improve speed and long blade life.
Straight seam welded pipe abrasive particle size and proportion: in order to obtain better uniform cleanliness and roughness distribution, ratio of abrasive particle size and design is quite important. Too much of the anticorrosive coating roughness in rush bum thin anchor lines; At the same time as the anchor lines too deep, anti-corrosion coating in the process of formation of air bubbles, serious impact on the performance of anticorrosive coating.
Precision steel tube is a kind of very hard and wear resistant thick-walled seamless tube, has a widespread application in the engineering construction, popularization of precision steel tube manufacturer today to give you the precision of the pressure steel pipe manufacture, forging, welding, welding, heat treatment production difficulty. Precision steel tube is a kind of very good compression resistance and abrasion resistance of thick wall seamless tube, and is not easy to rust, so we are widely used to daily daily life. Guys bike hob for precision welded tubes example is with orthodox thick-walled seamless tube of precision steel tube, because that can ensure that the bicycle clothing fashion, can also convenient bicycle compressive ability, normal orthodox thick-walled seamless tube precision steel pipes are also used in natural gas pipeline, the daily tasks for orthodox thick-walled seamless tube precision tube to do it.
