Cast Iron, Seamless Stainless Steel Pipe Manufacturing

Customer Needs

Cast iron pipe and seamless stainless steel pipe are often produced in a centrifugal caster. This is a rotating tube that has been preheated with gas flames on the outside of the tube. When the temperature is proper the molten metal is poured into the rotating mold and allowed to cool. The end result is a seamless pipe of either cast iron or stainless steel.

The customer has to insure that the tube is the correct temperature before pouring and that the cooling rate is followed to insure proper metallurgical properties and no cracks in the pipe. If the mold is too hot the refractory is destroyed. If the mold is too cold or the metal cools too fast the properties of the metal will not be achieved and cracks will occur. To measure this temperature we suggest the Modline 3 model 3R two color. In addition the customer may also measure the outside shell temperature to control the gas flames that heat the shell. A Modline 3, 3G with PID control is often used.
