SMLS Pipe Material properties

Stainless Seamless Pipe is a long steel material with a hollow section and no joints around it, which is made of a steel ingot or a solid tube billet through perforation to make a capillary tube, and then undergoes hot rolling, cold rolling or cold drawing process. Compared with other ordinary steel pipes, the stainless seamless pipe has a strong advantage in bending resistance. The tensile strength of Seamless pipe is more than 8-10 times that of ordinary steel, the elastic modulus is better than steel, and it has good creep resistance, corrosion resistance and shock resistance.

 

ASTM A312 TP316 seamless pipe is mainly used to transport media, the main function is to transport fluid, Seamless stainless steel pipe is usually a large diameter pipe, stainless steel seamless pipe has a strong yield strength, and bending resistance. The stainless steel seamless pipe production standard complies with ASME B36.19. Both process piping and public engineering piping are made of seamless pipes, which are often connected with accessories such as valves, tees, and elbows. Stainless steel seamless pipe is mainly used to transport fluid medium, and a large number of pipes are used to transport fluid, such as water, gas, natural gas, oil, boilers, mechanical parts, and sewage pipes.

Stainless Steel Seamless Pipe Hot Rolling Production Process

Stainless steel seamless pipe hot rolling production process: tube billet→heating→piercing→three-roll cross rolling, continuous rolling→pipe removal→sizing→cooling→straightening→hydraulic test→marking→warehousing.

After the tube blank is out of the furnace, it must be pierced by a piercing machine. Generally, the more common piercing machine is the tapered roller steel pipe piercing machine. This kind of piercing machine has high production efficiency, good product quality, large perforation diameter expansion, and can wear a variety of steel types. After piercing, the tube blank is successively cross-rolled and continuously rolled by three rolls. After extrusion, the tube should be taken off for sizing. The sizing machine uses a conical drill to rotate at high speed into the steel blank to punch holes to form a steel pipe (the inner diameter of the steel pipe is determined by the length of the outer diameter of the sizing machine drill).

 

After the steel pipe is sized, it enters the cooling tower and is cooled by spraying water. After the steel pipe is cooled, it will be straightened. After the steel pipe is straightened, it is sent to the metal flaw detector by the conveyor belt for internal flaw detection. If there are cracks, bubbles, and other problems inside the steel pipe, it will be detected.
