Annual operating domestic and imported Chengdu, Baotou, smelting steel, Lu Po, Anshan Iron and Steel, Anyang, Hongdu, Tianjin and other major steel seamless steel tubes, alloy pipe, boiler tube, stainless steel tube complete specifications, quality and quantity. The sale of products implementing national standards for all areas of construction, mining, textile, electric power, boilers, machinery, military and other. We always adhere to market-oriented, customer-focused Loudi seamless, quality of corporate lifeline, in good faith for the administration of enterprises, adhere to the principle of steady progress most serious, growing. Established a variety of services in the industry system, and forming a North, South, and the country's distribution network. With a good reputation and quality products, a strong, low price reputation more than 30 provinces, municipalities and autonomous regions, municipalities, the product won user dependent! Precision stainless steel pipes and industrial grade stainless steel seamless pipe can be compared from the following aspects 1, industrial-grade stainless steel tube material is stainless steel tube, ie mother pipe, cold drawn or cold rolled after annealing and pickling is not finished stainless steel seam tube. 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, and special sizes and requirements can also be customized, the production of precision stainless steel pipe to meet the special requirements of different users. 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. 4. surface finish good precision stainless steel tube, inside and outside surfaces of the tube finish Ra≤0.8μm, can make to the wall thickness of 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 carried out in the general industrial grade stainless steel seamless tube deep processing of Yellowstone, in the precision and smoothness obvious strengths, but its cost is relatively teach high, high-end stainless steel tube. The difference between the manufacturing process: galvanized steel and seamless steel pipe two kinds of areas, galvanized steel surface means a galvanized, welded pipe may be seamless, it may be seamless, seamless steel pipe means manufacturing process, welded and seamless points. These corrosion-resistant galvanized pipe, seamless steel pipe can withstand higher pressure. Because zinc-galvanized steel protection, not easy to rust, galvanized steel seamless lighter than if it is used in the balcony, it is best to use galvanized light pipe, seamless steel too with less suitable for balcony, Because seamless steel pipe wall thickness, the natural weight to heavy, and expensive than galvanized steel seamless costs to be high, there are galvanized steel is durable, useful life far more than seamless. If the quality, the use of more than two decades should not be a problem, of course, weld and paint to do well, not to affect the life of galvanized steel. Uses difference: in general is used to make galvanized steel fencing, fence, guardrail, balcony guardrail. Widely used in municipal projects, roads, factories, schools, development zones, gardens, squares, residential and other places.
