The alloying elements commonly used in Stainless steel seamless pipe include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., which make the stainless steel seamless pipe have high corrosion resistance and mechanical properties. ASTM A312 TP304 seamless pipe is a steel pipe resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acid, alkali, and salt. 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, Seamless ss 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.

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 continuous 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. After passing the quality inspection, the serial number, specification, and production batch number are painted on the steel pipe and put into storage.
