Q:What's the gate number of the precision steel pipe?
Precision steel pipe refers to the high precision steel pipe, the wall thickness and internal and external diameter can be controlled within 10 wire tolerance range
Q:What is the outer diameter and wall thickness of DN40 steel pipe?
DN40, refers to the diameter of 40mm, that is, an inch and a half, there are welded pipe and galvanized pipe,Ordinary wall thickness 3.5mm wt 3.84kg/mThicken 4.25mm weight 4.58kg/m
Q:What's the actual size of the DN25?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
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:Water, gas, steel pipes, thick steel wire means?
Water pipes, gas pipes and other collectively known as water gas pipe, generally galvanized steel pipe, so it can be called water and gas pipe. Most of them are welded steel tubes made of low carbon steel.
Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Fastener type steel pipe scaffold, fastener is the connection between steel pipe and steel pipe, and its form has three kinds, namely right angle fastener, rotating fastener, butt fastener
Q:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Major use differentiation:1, seamed tube can withstand the maximum operating pressure is generally less than 20 kg, which is the most secure use. It is generally used in water, gas, compressed air and other low-pressure fluid;2 seamless tube can withstand ultra-high pressure, of course, its wall thickness will also increase, which needs to be designed according to pressure requirements. It is generally used in high-pressure oil pipes, boiler tubes and other high temperature and high pressure equipment. There are also seamless tubes for structural purposes, depending on the design requirements.3, there are some seamed steel pipe seamless treatment tube, it is the weld annealing treatment, eliminate the residual stress of the weld, the weld and base material, the pressure range of basic and seamless pipe is. May also consider the use of.4, of course, the market also has some use overall heating after drawing steel pipe joints or mandrel rolling seamless steel pipe, mainly in small size, only in the shape of this kind of pipe belongs to the seamless tube, it is not very good
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Seamless steel pipe material is steel, but also seamless, high strength, used in high pressure, harsh environment occasions. The galvanized pipe is only made on the steel tube, which is similar to the so-called antirust paint
Q:What is the process of spiral steel tube production?
Visual inspection: some basic parameters are checked by professional technicians.6. ultrasonic inspection: 100% inspection of inner and outer weld seam and parent material on both sides of weld seam.
Q:What is the outer diameter of the steel tube?
The diameter of a steel pipe refers to the diameter of the steel pipe. The specifications of the steel tube is normal with diameter (diameter and thickness) said, for example 100MM outer diameter and wall thickness of 5MM tube is marked with 100*5.
