1Structure of  Seamless Steel Pipe API with  Q235 and  GR.B

Seamless steel pipe has a hollow section, a large number of pipes used for conveying fluid, such as oil, natural gas, gas, water and some solid materials, etc.. Compared to such as steel pipe and solid bar of steel, in flexural torsional strength are the same, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automobile transmission shaft, self frame as well as the construction of the steel scaffolding steel pipe manufacturing annular parts, can improve the material utilization rate, simplify the manufacturing process, material saving and working hours, has been widely used in steel pipe manufacturing.

Q:What's the use of steel pipe?
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. (
Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
Cold galvanizing is zinc plating, the general surface is relatively smooth, no zinc flowers, there are two kinds of resistance to fingerprints and non - Fingerprint
Q:What does the diameter of a steel pipe project mean?
Suppose we specify a standard that defines the nominal diameter of the same steel tube as G-1, then this G-1 is the same as DN50.I hope it doesn't make you any more confused, huh?. If you still don't understand, keep in mind that the nominal diameter is neither outside nor inside diameter.
Q:Is it good to buy a simple wardrobe or a steel pipe?
If the home place is big, buy Wooden, good-looking durable, if the place is small, buy cloth, easy to receive, mobile, tidy and cheap.
Q:Are steel tubes and round steel in weight or length when purchased?
A large amount of words is calculated by weight, less is usually calculated. According to the length between the length and quality of a material is usually a scaling. Steel belongs to the section, with the length of valuation, according to the classification of wall thickness and diameter; round steel belongs to building materials, mostly for the amount of weighing per ton of valuation, a small amount of more than according to the length multiplied by the conversion ratio of weight to that theory. But the latter is the valuation of tons of steel products between the uneven thickness, with uniform proportion will produce larger price difference, so the general price of different manufacturers are not the same, mostly depends on the quality, to a certain extent is to balance the diameter difference.
Q:Does seamless steel tube have a bend of 135 degrees?
In engineering, it is usually marked as "45 elbow" and has no "135" mark. The angle of the elbow is acute, so there will be no more than 90 degrees elbow.
Q:Steel pipe is particularly long, how to clean the inner wall of the pipe so that it can be thoroughly cleaned
High cleanliness requirements for ultrasonic cleaningUltrasonic cleaning principle: the pressure change of ultrasonic wave propagation in the liquid in the liquid cavitation phenomenon strongly, per second produced millions of tiny gas bubbles, these bubbles rapidly in large pressure under the action of not following the violent explosion, impact force and produce strong suction, enough to make the stubborn dirt quickly stripped.
Q:Seamless steel tube 89X4 meters, how heavy?
Generally seamless steel pipe wall thickness will be uneven, according to the theory, each meter is 8.3844 kilograms, but if the wall thickness is poor 20--30 wire, then the weight will increase some
Q:What kinds of steel pipe are divided into?
The steel pipe seamless steel pipe and welded steel pipe (tube) two categories. According to the section shape and can be divided into round tube shaped tube, round steel pipe is widely used, but there are also some square, rectangular, semicircular, hexagonal, triangular, octagonal shaped steel tube.Seamless steel pipe: seamless steel pipe is ingot or solid billet made by capillary hole, then hot, cold or cold drawing. Made of seamless steel pipe specifications with outer diameter * wall thickness mm. Number of seamless steel pipe cold and hot points of seamless steel pipe (DIAL) two categories.
Q:Can seamless steel pipe and ordinary steel pipe be welded?
If your project is a seamless steel pipe, so theoretically, you put the tube with connected is not used.But the actual engineering operation, design drawings will be put on the normal need to improve the requirements of the drawings to the actual requirements, so if is the need of seamless steel pipe, welded pipe in the end so can you see yourself.
