Product Description Seamless steel pipe for fluid use (fluid pipe) is a type of pipe with a hollow section and no weld from head to tail. The steel pipe has a hollow section and is widely used as a pipeline for conveying fluid, oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe has the same bending and torsional strength and is lighter in weight. It is a kind of economic section steel, widely used in the manufacture of structural...
Steel pipes are not only used to transport fluids and powdery solids, exchange heat energy, and manufacture machine parts and containers. They are also economical steel.Using steel pipe to make building structure grid, pillar and mechanical support can reduce the weight and save 20 ~ 40% of metal. Hot dip galvanized pipe is to make molten metal react with iron substrate to produce alloy layer, so that the substrate and coating can be combined. Hot galvanizing refers to pickling the steel pipe...
Galvanized steel pipes are divided into cold galvanized steel pipes and hot galvanized steel pipes. Hot dip galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and the coating of the two combination. Hot dip galvanizing is to first pickling the steel pipe. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of...
Product Description Classification of steel pipe: steel pipe is divided into seamless steel pipe and welded steel pipe (welded pipe) two categories. According to the section shape can be divided into round pipe and shaped pipe, widely used is circular steel pipe, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal shaped steel pipe. Hydraulic tests are carried out on steel tubes under fluid pressure to check their pressure resistance. Boiler...
Product Description Precision annealing refers to the technology of cold drawn precision steel tubes and precision bright steel tubes, which are annealed according to the customer's requirements for flexibility. Annealing is divided into open flame annealing and oxygen free annealing. Open fire annealing is to burn the furnace body to the temperature of steel pipe from 800 to 1100 degrees, to achieve the softness required by customers. Oxygen free annealing can not only achieve the softness, so...
Product Description Hot expanded seamless steel pipe is what we often call hot expanded pipe. The steel pipe with low density but strong shrinkage (seamless steel pipe) can be referred to as hot expanded pipe for short. A kind of finishing rolling process for waste pipe, in which the diameter of pipe is expanded by cross rolling or drawing. In a short period of time, the outer diameter of the steel pipe will become larger, and non-standard, special type of seamless pipe can be produced, with...

Product Description Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc. Galvanizing protects in two ways: It forms a coating of corrosion-resistant zinc which prevents corrosive substances from reaching the more delicate part of the metal. The zinc serves as a...
Product Description: Round steel refers to the solid long steel with circular section. Its specification is expressed in diameter (mm). For example, "50mm" refers to round steel with a diameter of 50mm. Classification by process: Round steel is divided into hot rolling, forging and cold drawing. The specification of hot-rolled round steel is 5.5-250mm. Among them, 5.5-25mm small round steel is mostly supplied in bundles of straight bars, commonly used as reinforcement, bolts and various...
