RHS name suggests non-standard pipe, it is a kind of square shape of the tube, a variety of material substance can form a square tube, it is the medium in, what to use, what to use in place, most of the pipe to steel pipe for the majority, After unpacking, smooth, curl, tube welding is formed, and then cut to the desired length and then rolled into the square from the round tube. Typically 50 per pack square tube in spot mostly to large-sized 10 * 10 * 500 * 500 * 0.8-1.5 ~~ 10-25, the pipe use is divided into square tube structure, decorative square tube, square tube construction Mechanical square tubes. Square tube, square tube called a non-standard square tube 31 * 94, which is the side looks like a pipe. After treatment process is rolled strip made. Redrawn square tube: the general is to strip after unpacking, smooth, curl, tube welding form, and then rolled into the square from the round tube and then cut into the required length. Square tube to be reasonable stacking, advanced first place (1) stacking principle requires under palletizing firm to ensure safe conditions, so according to species, size palletizing, different varieties of materials to be separately stacking, to prevent confusion and mutual corrosion; (2) prohibits the storage of steel pipe pile position near the corrosive effect of the article; (3) the stack end should be boosted, strong, smooth, prevent moisture or deformed material; and (4) of the same material by storage has Stacking respectively, to facilitate the implementation of the principle of pre-emptive advanced; (5) open dumps steel, the following must be wood or stone pad non-standard square tube 31 * 52, pile surface is slightly inclined to facilitate drainage, and pay attention to the material placed straight, to prevent the causing bending deformation; (6) the stack height does not exceed 1.2m non-standard square tube 33 * 33 manual operation, mechanical work no more than 1.5m, pile width not exceeding 2.5m; (7) stack should be left between the stacks and certain passages, check road is generally O. 5m, of access depending on the size of the material and transport machinery, generally 1.5 to 2. Om; (8) the end of booster stack, if the warehouse Chaoyang cement floor, elevate O. 1m can; if it is mud, must elevate O. 2 ~ 0.5m. If it is open space, concrete floor booster O · 3 ~ O · 5m, mud face booster 0.5 ~ O. 7m 9) open dumps angles and channels should stoop to put that mouth down, I-beam shall stand up, I can not be up and groove pipe, so water rust. [1000-pipe to introduce you to the star product - hot galvanized square tube] galvanized square tube performance galvanized square tubes has good strength, toughness, ductility and welding process performance and have good ductility, its alloy layer and steel base firmly attached, so hot galvanized square tube can be cold punching, rolling, drawing, bending and other forming without damaging the coating; for general machining such as drilling, cutting, welding, cold, etc. processes. Galvanized after surface bright and beautiful, it can be directly used for engineering on demand. Category galvanized square tubes have seamless and weld points, seamless square tube is made of seamless tube extrusion. Material Carbon Q235 (A, B); low-alloy Q345 (A, B) use galvanized square tubes due to its excellent performance is often used: glass walls, power transmission tower, communications grids, water and gas transmission, wire sets tubes, houses, bridges, metal structures, power transmission, etc., in recent years has a lot to be used. Acceptance criteria galvanized square tube generally determine their eligibility appearance in the pipe outer wall surface where there is leakage of plating, pitting, white, heavy leather, air bubbles, the pan-green and the frequency of occurrence is too high, it is determined that substandard products . But in the product standard deviation of the product have a predetermined range, namely the size of "tolerance" of non-standard square tube 31 * 53, non-standard pipe (certification), non-standard 1000-square tube by the Tianjin Steel Pipe Co., company. 1000-Tianjin Steel Pipe Co. (www.tjqre.com) (www.tjqre.com) is Tianjin, steel leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In the 1000-pipe leadership with the staff warmly welcome all inquiries negotiations to create the 1000-pipe a better future.
