Special-shaped seamless pipe is the general term of seamless pipe with other cross-section shapes except circular pipe. According to the different shapes and sizes of steel pipe sections, it can be divided into equal wall thickness special-shaped seamless pipe (code D), unequal wall thickness special-shaped seamless pipe (code BD), variable diameter special-shaped seamless pipe (code BJ). . Special seamless pipe is widely used in all kinds of structural parts, tools and mechanical parts. Compared with the round pipe, the special-shaped pipe has larger inertia moment and section modulus, larger bending and torsion resistance, which can greatly reduce the structure weight and save steel.
A514 grade B structural steel,The excellent properties of wear resistant steel plate meet the strict requirements of high strength, high wear resistance, stability, straightness and surface quality. The combination of high hardness, high strength and excellent impact toughness makes plate become an ideal material for a wide range of applications. The production thickness of wear resistant steel plate is generally between 8-100mm.
A514 grade B structural steel,X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.A514 grade B structural steel
