Q:A333gr6 steel pipe and domestic material of the same?
A333Gr.6 steel is no nickel steel is a kind of fine grain aluminum low temperature toughness of steel, therefore, also called Al killed steel. A333Gr.6 belongs to the United States ANSI and ASTM-SA333 cryogenic steel standards and is used at the lowest impact temperature of -46 degrees celsius. Its temperature, range of use and fracture toughness value are similar to those of domestic 16Mn steel (the minimum usage temperature of 16Mn steel is -40 degrees Celsius).
Q:What kinds of steel pipe are divided into?
According to the weld shape can be divided into longitudinal welded pipe and spiral welded pipeStraight welded pipe: the production process is simple, high production efficiency, low cost, rapid developmentSpiral welded pipe: strength ratio of longitudinal welded pipe is high, with a narrow billet production of large diameter pipe, also can use the blank production of the width of the same diameter of different pipe. But with the same length of straight pipe, weld length of 30~100%, and the production rate is low. Therefore, the smaller diameter pipe most used straight large diameter pipe welding, mostly using spiral welding.Dividedagain general welded pipe, galvanized pipe, blowing pipe, wire tube, pipe metric, roller tube, deep well pump, tube for automobile, transformer tube, welding, welding of thin-walled tube shaped tube and spiral welded pipe.General general pipe: pipe used for conveying the low-pressure fluid. Q195A, Q215A and Q235A made of steel. Also can be used for easy welding of mild steel. The other pipe to conduct water pressure, bending and flattening test, have certain requirements on the surface quality, usually the delivery length is 4-10m, often requires a fixed length (or size) of delivery. The specifications of welded pipe with nominal diameter (mm or inches) nominal diameter and different pipe wall thickness, according to the provisions of general steel and thicker steel two, steel pipe end is divided according to form of threaded and non threaded two.
Q:Seamless steel tube with the tube with what is the difference?
Seamless steel tube is integrally formed with welded steel pipe steel plate butt welding and welding seam.
Q:How to distinguish seamless pipe and welded pipe?
If it is seamless pipe, the port can be seen inside and outside the pipe there is no welding meat exists, and even if the welding pipe welding processing, the pipe weld is very easy to observe.
Q:What is PE coated steel pipe? Seek explanation
PE coating on the inner wall of steel pipe steel pipe is covered with a layer of polyethylene plastic polymer, PE, polyethylene (Polyethylene of raised temperature is the abbreviation of resistance English), the scope of application of the general PE pipe water supply pipe to a temperature below 40 DEG C, cannot be used for hot water transmission pipeline.
Q:What's the difference between straight steel pipe and seamless steel pipe?
Observe whether there is weld seam. Welded pipe without treatment, there are obvious weld, there are bulges, like scars. A better point will shave off the weld, but there is a distinct difference between the eye and the eye. Also a small number of pipe will be processed after cold rolling, surface roughness and accuracy are relatively high, may be counterfeit seamless pipe sales. Careful observation will still show that the pipe wall will have a continuous spiral, metal luster slightly brighter, that is, the original welding seam, metallographic structure and other parts of the difference. To tell the truth, the layman would have to observe that it might be a little difficult.
Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
General use seamless steel tube: is with 10, 20, 30, 35, 45# and other high-quality carbon steel, 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot-rolled or cold rolled. Seamless tubes made of low carbon steel, such as 10, 20, are mainly used for fluid delivery pipelines. 45. Seamless tubes made of medium carbon steel such as 40Cr, used for the manufacture of mechanical parts, such as parts of automobiles and tractors. General use of seamless steel pipe to ensure the strength and flattening test. Hot rolled steel tubes are delivered in hot rolling or heat treated conditions. Cold rolled in heat treated state.
Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Rectangular fastener: used for the connection of two vertical intersecting steel tubes. It relies on the frictional force between the fastener and the steel tube to carry the load.Swivel fastener: used for connecting two steel tubes intersecting at any angle
Q:What does cathodic protection of steel tubes mean?
The corrosion of metals causes great economic losses directly or indirectly. Foreign statistics show that every year due to corrosion and scrap metal materials, equivalent to 20~40% of metal production, the world every year due to corrosion and loss of metal reached more than 1 tons.
Q:Galvanized steel pipe, PPR pipe, PE pipe, U-PVC pipe and HDPE double wall corrugated pipe and what is the difference between the characteristics of
PE pipe, polyethylene pipe, the past is also commonly used in low temperature water, but because of its short life now use less prone to aging, more PE material for the production of plastic bags;
