Q:What are the main aspects of precision steel tubes?
Products according to their application areas are divided into: automotive, precision machinery tubes; power plants, nuclear power tubes; titanium and titanium alloy tubes; chemical tubes; varieties include colored, black; seamless; welding; general and special-shaped
Q:Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
Other commonly used theoretical weight formulas per metre:Thread steel (Kg/m):W=0.00617 * D * D, D - sectional diameter (mm)Fang Gang (Kg/m):W=0.00785 * a * a, a - edge width (mm)Flat steel (kg/m):W= 0.00785 * b * D, B -- edge width (mm) d - thickness (mm)Round steel rod (kg/m),:W= 0.006165 * D * D, D - diameter (mm)
Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
Seamless steel pipe, hot-rolled and cold-rolled (DIAL) seamless steel pipe two categories.Hot rolled steel tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel pipes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..Cold rolled seamless steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube and other steel tube, including carbon thin-walled steel, alloy thin-walled steel, stainless steel, thin steel tube. The outer diameter of hot-rolled seamless tube is generally greater than 32mm, the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless steel tube can reach 6mm, the wall thickness can be up to 0.25mm, the outer diameter of thin-wall pipe can be 5mm, the wall thickness is less than 0.25mm, and cold rolling has higher precision than hot rolling dimension.
Q:What are the lengths of scaffold steel tubes?
Scaffold tubes are our name for materials used to build scaffolding, because most scaffolding uses tubular bamboo or steel tubing. Bamboo and other bamboo is for a long time in the use of the scaffolding tube, but due to lack of safety and durability, now only in rural and urban area construction is lagging behind some of the home building small building has been used. The modernization construction, the most commonly used type of scaffolding pipe is steel pipe, the scaffolding should not only meet the demand of workers, but also to meet the characteristics of scaffolding firm and durable, so tough hard steel is the best choice. The selected steel pipe generally requires smooth surface, no cracks, no bending, no rust, and meet the relevant national standards.
Q:What are low-pressure carbon steel tubes?
Any of various steels that contain less than 2.11% of the mass of carbon but contain no alloying elements. Sometimes referred to as plain carbon steel or carbon steel.Carbon steel, in addition to carbon, usually contains a small amount of silicon, manganese, sulfur and phosphorus.1) according to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and easy to cut structural steel three categories, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two kinds;(2) by refining methods can be divided into open hearth steel, converter steel;(3) according to deoxidization methods, they can be divided into boiling steel (F), killed steel (Z), semi killed steel (b) and special killed steel (TZ);(4) according to the carbon content of the steel can be divided into low carbon steel (WC = 0.25%), carbon steel (WC0.25% - 0.6%) and high carbon steel (WC>0.6%);(5) according to the quality of steel, carbon steel can be divided into ordinary carbon steel (phosphorus, sulfur, higher), high quality carbon steel (low phosphorus and sulfur) and high quality steel (lower phosphorus and sulfur) and super quality steel.Description: the carbon content in general carbon steel is higher, the hardness is higher, the strength is higher, but the plasticity is lower.
Q:Is the PVC tube a plastic tube or a plastic tube?.
PVC is actually a vinyl polymerization substance, whose material is a non crystalline material. Polyvinyl chloride (Poly, Vinyl, Chloride, PVC), it is obviously impossible to steel, we often say that iron and steel, the steel must be the main component of iron, Fe, inorganic. And PVC, polyvinyl chloride, is an organic substance. Therefore, PVC can not be called steel, and PVC constitutes a large number of substances, not confined to the pipe type.
Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
200 refers to the diameter of the pipe. Personally, you should be an electrical professional, but the electrical specialty rarely uses the 200 pipe diameter unless it is used when the buried cable passes the road;
Q:Is the diameter of the steel tube indicated by the outer diameter by the wall thickness or by the inside diameter by the wall thickness?
The specification for steel tubes is the outer diameter multiplied by the wall thickness.Generally speaking, the diameter of the pipe can be divided into outer diameter (De), inner diameter (D) and nominal diameter (DN).
Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
Screw on the line, mainly anti-corrosion and insulation, seamless pipe caliber restrictions, so the price is high, with the most affordable screw can meet the requirements, 377 and 273 of the spiral 3920 yuan / ton, straight seam is about 4350
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
GB/T3091-2008: DN150 welded steel pipe, wall thickness of 6mm, the theory of the weight of welded steel pipe 24.02kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 6mm, C=1.02, DN150, theoretical weight and wall thickness of 6mm galvanized steel 1.02*24.02= 24.5kg/m.
All these steel pipes are suitable for the industries of oil, natural gas,ship building,chemical, environmental protection,boiler, water conservancy, electrical industry,steel structure, building and other related fields.Our company following the principle that ‘customer supemacy, business integrity’We will do our best to supply best products and service to our customers. We expect mutual benefit.
