Q:How to descaling galvanized steel pipe?
Is red rust or white rust, red rust is the base material rust, white rust is Zinc Coating Rust
Q:Can galvanized pipe be welded with seamless steel tube? What should I do to connect?
To look at the use of concrete after welding, if the stress is relatively large and thin galvanized pipe wall is recommended to not use welding, if the requirement is not high Po mouth welding should be welding depends on galvanized pipe material selection electrode generally no sealing material are 20
Q:What does the diameter of a steel pipe project mean?
Generally, the diameter of steel pipe has three common diameters: outer diameter, inner diameter and nominal diameter.The first two are well understood.Nominal diameter refers to the national standard to specify the general diameter of a certain national standard pipe. It is only a model representation. It is neither outer diameter nor inner diameter.
Q:What does GALV mean in a steel tube?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.
Q:What are the uses of seamless steel tubes?
Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, such as rolling bearing ring, Jack and so on, has been widely used in steel pipe manufacturing.
Q:DN80 seamless steel tube, what is the standard thickness?
Generally speaking, the diameter of the pipe can be divided into outer diameter, inner diameter and nominal diameter. Tubes are made of seamless steel tubes. The outer diameter of the tubes is indicated by the letter D, followed by additional outer diameter dimensions and wall thicknesses such as seamless steel tubes with an outer diameter of 108.
Q:Where is the difference between seamless steel pipe and welded pipe?
The steel tube is a hollow steel strip, used as pipe conveying fluid, such as oil, gas, water, gas, steam, in addition, the bending and torsional strength of the same, the weight is light, so it is widely used in the manufacture of machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.Pipe classification: steel pipe seamless steel pipe and welded steel pipe (tube) two categories. It can be divided into round tube and special-shaped tube according to the sectional shape. The round steel tube is widely used, but there are some special-shaped steel tubes such as square, rectangle, semicircle, hexagon, equilateral triangle and octagon.
Q:What is the outer diameter of the steel tube?
The outer diameter refers to the maximum diameter including the thickness of the steel tube, the inner diameter is the length of the hollow part inside, and the outer diameter minus the inside diameter is the thickness of the steel pipe
Q:What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?
The difference between the process is that the hot dip galvanized pipe is dipped in the molten zinc bath and the galvanized pipe is plated with a metallic surface by means of unidirectional current in the plating bath. Hot plating process is fast, the coating is thick and consumes more zinc. Ordinary galvanized slow speed, thin coating.
Q:How seamless steel tube is formed?
Overview of two kinds of steel pipe process:1, cold drawing (rolling) seamless steel pipe: round tube to heating to perforation, annealing, pickling, leading to oil (copper), multi pass drawing (Leng Zha), the blank pipe, heat treatment, straightening, pressure test (testing), marking and warehousing.2. Hot rolling (extrusion seamless steel tube): round tube billet, heating, piercing, three roll cross rolling, rolling or extrusion, removal of pipe, sizing, reducing (diameter or reducing), cooling, blank tube, straightening, water pressure test (or flaw detection), marking and warehousing.
