Hot Selling for Imported A106 Seamless Steel Pipe - A106gr.B seamless steel pipe manufacturer direct sales – Weichuan

ASTM A106 seamless steel pipe belongs to American standard steel pipe, including a106-a and a106-b. The former is equivalent to the domestic 10# material, and the latter is equivalent to the domestic 20# material. It belongs to ordinary carbon steel series and is one of the commonly used materials. ASTM A106 seamless steel pipe includes two processes: cold drawing and hot rolling. In addition to different production processes, they are different in accuracy, surface quality, minimum size, mechanical properties and organizational structure. It is widely used in petroleum, chemical industry, boiler, power station, ship, machinery manufacturing, automobile, aviation, aerospace, energy, geology, construction, military industry and other industries.

ASTM A106 calculation method for bearing pressure of seamless steel pipe

S = 8; P is less than 17.5MPa seamless steel pipe, s is the safety factor seamless steel pipe, and the wall thickness is 3mm,

Allowable pressure of pipe P = (2)* σ/ S* δ) / D

Where: the pressure is p and the wall thickness is δ, What is the maximum pressure of seamless steel pipe?

Let the tensile strength of the material be σ, Zhan Rongrong learned that the outer diameter of the pipe is D;

Pipe wall thickness δ=( P*D) / (2* σ/ S)

Where s is the safety factor;

Because P is less than 7MPa, Zhan Jirong learned that s is selected as s = 4;

We choose the safety factor as s = 6; The tensile strength of 20 steel is 410mpa, the steel market, and the outer diameter of the pipe is d

American standard steel pipe is a long strip of steel with hollow section and no joints around it. Steel pipe has hollow section and is widely used as pipeline for conveying fluid. American standard seamless steel pipe standard, such as pipeline for conveying oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe has the same bending and torsional strength and light weight. It is an economic section steel. It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction. Manufacturing ring parts with steel pipes can improve material utilization, simplify manufacturing processes, and save materials and processing hours, such as rolling bearing rings, Jack sleeves, etc. steel pipes have been widely used for manufacturing. Steel pipe is also an indispensable material for all kinds of conventional weapons. Gun barrel and barrel should be made of steel pipe. Steel pipe can be divided into round pipe and special-shaped pipe according to different cross-sectional area and shape. Because the circular area is the largest under the condition of equal circumference, more fluid can be transported by circular pipe. In addition, when the ring section is subjected to internal or external radial pressure, the force is more uniform. Therefore, most steel pipes are round pipes.

Among American standard steel pipes, ASTM A53 gr. B seamless steel pipe for general purpose, ASTM A106 / A53 gr. B chamfered and chamfered steel pipe, bs1387-1985 British standard ERW high frequency welded pipe and galvanized pipe, ASTM A333 – 40 ℃ – 101 ℃ low temperature seamless steel pipe, ASTM A179 seamless steel pipe for heat exchanger and condenser. Steel pipe length: 5.8m, 6m and up to 12m, It can also be scaled according to user’s needs.

The outer diameter of the product is 1 / 2 “- 28″, 21.3-711.2mm, and the wall thickness is sch30, sch40, STD, XS, sch80, sch160, XXS, etc. the seamless pipe can be subject to surface anti-corrosion treatment as required, with plastic pipe caps at both ends, chamfering as required, and commodity inspection.
