Seamless pipe continuous casting

Seamless billet piercing process according to the different requirements and the production methods can be divided: there ingot, billet, rolling slab, billet and forging a hollow slab.

If you press the tube cross-sectional shape, then you can also be divided into: round, square, octagonal and square wave-shaped tube and so on. Seamless steel pipe processes for continuous casting: steel continuously through a water-cooled mold, after continuous cemented crust pulled from beneath the mold exit by water cooling, after all the casting solidification process into billets.

Now a large number of applications is seamless production round billet continuous casting and rolling. Only for medium-sized ingot cycle pipe mill. Using rotary piercing round billet push piercing and piercing pressure is often used billet. Continuous casting round billet production is seamless application of more blanks on the current international, which is also a measure of a country's steel production technology logo. Continuous casting round billet with finished product rate, low cost, low power consumption, stable organizational performance characteristics, the mainstream tube development. Forging stock is often used on special alloy steel and rolling method is difficult to obtain or economic uneconomical.

Centrifugal casting method is mainly used for high-alloy steels and difficult perforated metal.



Tech & Service of Seamless pipe

Seamless pipes are extensively applied for the nuclear device, gas, petrochemical, ship building and boiler industries. Seamless pipes dominates 65% of market share in Chinese boiler industry.

How to make seamless pipe(seamless pipe process)?
Hot Piercing Workshop
Piercing process
The cross roll piercing and pilger rolling process in the size range from approx. 250 to 660 mm outside diameter.
Precision cold drawn steel tube production process
Pipe weld cracks
often follow different mechanisms can be divided into two types of thermal cracking and cold cracking.
How to calculate a steel pipe and tube theoretic weight
Calculate a steel pipe?
Pipe fittings are necessary to join together pipes, or to change the direction of an existing pipe.
Pipe beveling
Pipe beveling is the process where an angle is formed between the edge of the end of a pipe or tube and a plane perpendicular to the surface.
Steel pipe cutting machine
Pipe cutting
Cutting tools have a grinding wheel piece cutting machine (also known as toothless saw), hand saw, cutter and other hand tools.
Packing the steel pipes
There are probably hundreds of different methods for packing a pipe, and most of them have merit, but there are two principles that are vital for any method.
