High frequency welded pipe mill line

About 100 years ago, by introducing continuous steel, welding tube, welded pipe milling machine began to pop up. Steel tube mill began in the bank into a book to read, straightening, and shear end welder. Mill "forming" part is by a breakdown department and forming department, need 3 to 6 pass.

Pipe mill manufacturer in China

Our company was founded in 2002,which is professional in designing and manufacturing any types of high-frequency welded pipe unit, pipe mold and burr-free computer cutting saws as well as the advanced steel tube mill.

The introduction of Tube Mill Line

The tube mill line may also be termed pipe making machine. The tube mill line mostly consists of two varieties, which can handle distinctive supplies.

Preperforated coiled tubing

Preperforated pipe milling machine is produced by forming a perforation in flat strip of raw material, forming a hollow, cylindrical tube from the flat strip, and placing a removable plug into the perforation, so as to form a fluid-tight seal. A sealing element may be placed into the perforation. The perforation may comprise a hole, into which first and second countersinks may be formed.

Seamless Steel Pipe Production

The hot rolled seamless steel pipe is produced on the seamless pipe mill. By examining and eliminating the surface defect,the solid pipe billet is cut into the required length. Before punching a hole, the center of the punching side should be marked and the billet should be heated on the heating furnace.Under the function of mill roll, a cavity is formed in the billet called semi-manufactured steel pipe.

High speed attachment for pipe milling machines

A variable speed pipe milling machine attachment, and a method for its use, that is efficiently configured for minimal reduction of the spindle-to-table distance of a steel pipe machine, such as the well-known Bridgeport miller, and which when attached to a milling machine having a maximum spindle speed of

What is Structural Tubing?

Most people don't even notice structural steel pipe mills, but it is an integral part of everyday life for many people. This sturdy alternative to solid steel is used in an impressive array of industries and products, from shopping carts to hand rails to truck bumpers. These tubes come in many shapes and metals, all intended to serve a unique function.

What Are the Different Types of Milling Tools?

Pipe milling machines utilize several different types of milling tools for particular applications. The most common types of milling tools are end mills and slot drills which perform similar actions. Roughing end mills create irregular cuts and slab mills produce wide cuts. Hollow mills are used to smooth cylinders while ball nose cutters produce three dimensional shapes.

Method for tube end preparation and milling head therefore

Tube ends such as those of boiler tube banks, are prepared utilizing any of various combinations of processes which include a step of micro-diameter tube mill line removal from a portion of a tube end, including an area below a beveled segment, or segment to be beveled.

Transition beam forming section for tube mill

A transition forming unit for a tube mill machine is provided for forming a strip into a generally annular shaped cross-sectional configuration. The forming process is performed by a plurality of roll assemblies mounted on at least a pair of spaced longitudinally extending beams, one disposed on each side of the longitudinal axis of the forming unit.
