Carbon steel Seamless Pipe connection method

- Nov 24, 2020-

(1) The importance of the structure of heavy industrial structures, large-span structures, high-rise or super-high-rise civil construction structures or structures and other important structures, should consider the selection of good quality seamless steel tubes, the general industrial and civil architecture, according to the nature of the work can be selected by the ordinary quality of seamless steel tubes.
(2) The load situation directly under the structure of the dynamic load and the structure of the strong earthquake area, should choose the comprehensive performance of seamless steel tubes; Generally, the structure of static load can choose the lower price seamless steel tube. (3) connection method welding deformation, welding stress and other welding defects can be caused by weld process, and there is a risk of cracking or brittle fracture in the structure.


Therefore, the welding structure of the material requirements should be strict. (4) The structure of the temperature and environment, seamless steel tube at low temperature is easy to cold and brittle, so in the low-temperature conditions of the structure, especially the welding structure, should be selected with good anti-low temperature brittle performance of the calm steel.


In addition, the open-air structure of Taiyuan seamless steel tubes prone to aging, harmful medium effect of seamless steel tubes prone to corrosion, fatigue and fracture, also should be differentiated to choose different materials. (5) too thick seamless steel tubes, thin seamless steel tube roll rolling times, rolling compression ratio is large, the thickness of the seamless steel tube compression ratio is small, so the thickness of the precision steel pipe not only less strength, but also plastic, impact toughness and welding performance is poor. Therefore, the welded structure with large thickness should be made of seamless steel pipe with good material.

ASTM A106 Gr.B Seamless Carbon Steel Pipe

     ASTM A106 Hot Rolled Seamless Pipes                             Hot Rolled Carbon Steel Seamless Pipes

 

Seamless Steel Pipe,as the name suggests,is a pipe without a seam or a weld-joint.

Seamless Steel Pipes is a tubular section or hollow cylinder,usually but not necessarily of

circular cross-section,used mainly to convey substances which can flow-liquids and gases(fluids),slurries,powders,powders and masses of small solids.
