Precision stainless steel pipes and industrial grade stainless steel seamless pipe can compare from the following aspects 1, industrial-grade stainless steel tube material is stainless steel tube, namely blank pipe finishing small-diameter steel pipe, cold drawn or cold rolled after annealing and pickling, stainless steel seamless pipe is finished. The main features of industrial grade stainless steel seamless pipe is without welding seam, can withstand greater pressure, but through solid steel surface melting process (that is, we usually say that the annealing treatment) pipe can be bent, reaming and other processing. 2, precision stainless steel tube products emerged in recent years, mainly in the hole, the outer dimensions with tight tolerances, surface finish and steel have high demands. Precision stainless steel tube 1. The outer diameter of the smaller features, in general, precision stainless steel tube outer diameter of 6 mm or more in general, Wenzhou Renault tube can produce diameter 6-133 mm steel pipe. High precision can do small batch production, I plant the production of precision stainless steel tube finishing MOQ is 500KG special small-diameter pipe, and special sizes and requirements can also be customized, the production of precision stainless steel pipe to meet the different users special requirements. 3. Accuracy of relatively high precision stainless steel pipe, steel pipe and the bore diameter tolerance 6-60 of the general control within plus or minus 3-5 silk. Good surface finish small diameter pipe 4. The precision stainless steel pipe, tube and external surface finish Ra≤0.8μm, can make to the wall thickness 0.5mm. Then polished inner and outer surfaces of the tube finish up Ra≤0.2-0.4μm (such as a mirror). 5 steel pipe superior performance, the metal is relatively dense, steel can withstand the pressure becomes larger. In short: precision stainless steel tube is for further processing in the general industrial grade stainless steel tube, precision and smoothness in the obvious strengths of small diameter cold drawn steel, but its cost is relatively teach high, high-end stainless steel tube.

Company Pipe: the most homogeneous specifications, the lowest price, best quality, best service! We welcome new and old customers to guide our company to negotiate business and practical skills of steel pipe manufacturers custody 1. Select the appropriate venues and steel warehouse storage space or warehouse, should be selected in clean, smooth drainage area, away from harmful gases or dust factories and mines. The presence on the ground to remove weeds and all sorts of things, to keep the steel clean. In a warehouse not with acid, alkali, salt, cement, steel and other aggressive materials stacked together. Different varieties of steel should be stacked separately, to prevent confusion, avoid contact corrosion. Heavy sections, rails, shame steel, large diameter steel pipe, forgings, etc., may open dumps. Small and medium steel, wire rod, rebar, caliber steel pipe, steel wire and wire rope, etc., can be expected in a well-ventilated storage shed, but it must be the underlying thatch. Some small steel, sheet, strip, silicon, or thin-walled steel pipes of small diameter, a variety of cold-rolled, cold-drawn steel and high prices, corrosive metal products, can be stored for storage. Treasury should be selected according to the geographical conditions, the general ordinary enclosed warehouse, that is the roof with walls, doors and windows tight, with the Treasury ventilation device. Treasury requires attention to ventilation sunny, rainy close attention to moisture, keep proper storage environment. 20 # small diameter pipe (FIG), 20 small-diameter steel pipe, small diameter steel pipe provided by the Shandong Liaocheng Steel Pipe Manufacturing Co.
