Seamless pipe can be manufactured with very accurate dimensions and schedules. However, there are restrictions on the fabrication of large diameter pipes. Seamless pipe is widely used in the manufacture of pipe fittings such as elbows, bends, and tees.
According to users’ needs, the welded tube mill machines can be designed into the multifunctional combination equipments for producing section steel, square pipes and round pipes, realizing one machine with multiple functions.
Based on the material, the workload and the application a slitting line is set up for, a steel coil slitting line may contain machines arranged into several stations with the automatic control system, or it can be a simple slitter machine to which the master coil is fed manually by operators.
Roll forming is a flexible and cost effective process for forming metal into customised cross-sectional profiles. Often referred to as "cold roll forming" because the metal is formed in its hardened state, roll forming is used in a wide variety of industries to produce parts and components, ranging from metal forming in automobiles to household appliances, aircraft and houses.
Architects and engineers are designing structures with new and innovative shapes due in part to new steel chemistries and improved flat rolling technologies.
In the classic sense, a tube mill is a kind of welded roll form system; however, not every welded roll form system is a tube mill. Tube mills are welded roll form systems that have been fine-tuned to run a specific diameter range, typically at fast speeds.
