Product Description:

1、Structure of Galvanized hollow section Pipe API103: 

Galvanized hollow section Pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. We company professional to provide these serious of pipes and what we can give you is not only in good sprice, the most important is we can provide you good quality.

Q:What is the outer diameter and wall thickness of the welded steel pipe of national standard DN250?
DN250 is the nominal diameter, the outer diameter of the steel pipe is 273mm, the thickness is above 6.5mm.
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
DN150 4mm wall thickness welded steel pipe theoretical weight is 16.21kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 4mm, C=1.032, DN150, theoretical weight and wall thickness of 4mm galvanized steel is 1.02*16.21=16.7287kg/m = 16.73kg/m.
Q:How to identify stainless steel pipe and steel pipe?
Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
Q:Stainless steel tube, also known as why tube?
According to the end of the pipe can be divided into light pipe and wire tubeThe tube can be divided into ordinary tube and special thread tube
Q:What is ND steel pipe?
ND steel 09CrCuSb steel is currently the most ideal "resistance to sulfuric acid dew point corrosion in steel (ND steel, ND steel, 09CrCuSb steel, 09CrCuSb steel), ND steel is widely used in the manufacture of economizer, served in the high sulfur content in flue gas of air preheater, evaporator and heat exchanger equipment for resist sulfur smoke gas dew point corrosion.
Q:Can galvanized steel tubes simmer?
Galvanized steel pipe can simmer bending.Is a set of bending bending bending die, no matter what kind of equipment, most are used in pipe, mainly used for oil and gas, infusion, more plays an important role in aircraft and engine.
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
304 stainless steel tube with the diameter of 25*2-3 said: material for 304 (the equivalent of the American brand, Chinese numbered S30408 stainless steel or 06Cr19Ni10 stainless steel), diameter (OD) for 25mm, for the seamless steel pipe wall thickness of 2 to 3mm.
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:How to establish a concrete-filled steel tubular column model in ANSYS?
First, you have to choose at least three or more types of materials. Modeling is a little complicated. Strongly recommended that the landlord to see "ANSYS in civil engineering applications", where there is such an example, you step by step, step by step back, and then in accordance with their own requirements modeling, OK. Wish you success
Q:What are the main aspects of precision steel tubes?
Precision tube is a kind of seamless steel tube with high precision and high brightness produced by cold drawing or cold rolling.
