Mild Steel Pipe, Mild Steel Seamless Pipe, MS Seamless Pipe Manufacturer & Supplier
Mild Steel pipes are manufactured using low carbon (less than 0.25%) steel. As MS Pipes are made from mild steel they can easily be welded and formed in various shapes and sizes for pipelining and tubing purposes.
Mild Steel (MS) seamless pipe is a capillary pipe made by piercing a steel ingot or a solid tube blank, and then hot rolling, cold rolling or cold rolling. Seamless carbon steel pipe occupies an important position in my country's steel pipe industry.
Features of mild steel pipe:
1. Mild steel seamless pipe is a carbon steel with a carbon content of less than 0.25%. Because of its low strength, low hardness and softness, it is also called low carbon steel.
2. The annealed structure of mild steel seamless pipe is ferrite and a small amount of pearlite, with low strength and hardness, but good plasticity and toughness.
3. Mild steel seamless pipe has good cold forming performance, and can be cold formed by crimping, bending, stamping and other methods.
4. The weldability of mild steel seamless pipe is good. It is easy to accept various processing such as forging, welding and cutting.
MS Seamless pipe Manufacturing Process:
The raw material of the Seamless carbon steel pipe is a round tube blank, which is cut by a cutting machine into a billet with a length of about 1 meter, and is sent to the furnace for heating via a conveyor belt. The billet is fed into the furnace and heated at a temperature of approximately 1200 degrees Celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is a key issue.
After the round tube billet comes out of the furnace, it is pierced by a pressure piercing machine. Generally, the more common piercing machine is the tapered roller piercing machine. This type 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 round tube billet is successively cross-rolled, continuous rolled or extruded by three rolls. After squeezing, take off the tube and calibrate. The sizing machine uses a tapered drill bit to rotate at a 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 drill bit of the sizing machine.
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 straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection. If there are cracks, bubbles, etc. inside the steel pipe, it will be detected.
After the quality inspection of steel pipes, strict manual selection is required. After the quality inspection of the steel pipe, paint the serial number, specification, production batch number, etc. with paint. It is hoisted into the warehouse by a crane.
