Tube Mill

The premium quality of High Speed Tube Mill for Precision Tube and other international with the latest technology Bur Free/ Cold Saw Cutting Machine. Automatic operation and low maintenance make it high quality. 

TUBE MILL is a combination of equipment installed in a line for the production of HIGH FREQUENCY INDUCTION WELDED carbon steel tubes.  The process involved is cold forming of carbon steel strip in circular shape, longitudinal welding, sizing, converting into rectangular square shape and cutting to predetermined length.

Tube Mill mainly consists of strip preparation, pipe forming, welding, cooling, sizing straightening, pipe cut-off unit and pipe take off unit. A forming motor of and a sizing motor and power transmission is done by workgear boxes drives the whole machine.

Nirmal offers Slitting Lines for Hot Rolled and Cold Rolled steel strips to deliver top caliber of cut strips. These lines are of different plans to suit client's necessities as far as mechanization level, adaptability of activities and creation limit. 

A coil slitting line is used to create smaller coils to a specific width or weight. A master coil will be threaded into the slitting line and from there a coil will be formed to your desired width. The slit coils that are produced (sometimes referred to as mults or strips) are then recoiled. Slitting lines can be equipped to slit ferrous and non-ferrous metals, as well as advanced and ultra-high strength steels, and aluminum.The coil slitting process involves large coils of metal being cut using sharp rotary blades. Straight lines are cut lengthwise into the large coil, the resulting strips of metal are narrower in width. As the coil runs through the slitter, two circular blades (one on top and the other on the bottom) make the cuts.

The Hot Dip Galvanizing is a metallurgical interaction which assists with shielding steel materials from consumption brought about by expected openness to brutal conditions. This can be accomplished through various exciting sorts and it shields materials over the long haul from debasing while at the same time keeping up with their properties unaltered. 

The Hot Dip Galvanizing interaction comprises lowering metal items in a liquid zinc shower. This causes a metallurgical response that bonds the two metals' outer layers, making a homogeneous and exceptionally safe surface. 

Through immense research of the market, Nirmal came up with a superior grade Pipe Galvanizing Plant which is designed and fabricated using high quality steel and components, specially designed for galvanizing metal pipes to prevent them from corrosion. Plant is fabricated according to the industry laid parameters and the requirements of our customers.

We are experienced professionals possessing in-depth knowledge and expertise in manufacturing various types of galvanizing plants according to international standards. 

In tube galvanizing it has certain steps which constitutes the whole process of hot dip. The plants are highly efficient and allow a constant and continuous production for each diameter of a pipe in process.

Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc-iron alloy and zinc metal. While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc. This reaction is a diffusion process, so the coating forms perpendicular to all surfaces creating a uniform thickness throughout the part. Hot dip Galvanizing is usually very well tested in unique details in order that defect free products usually are sent from consumers' place. Hot dip galvanizing gives some advantages like limited pickling time period, short manufacturing charge, reduced creation price tag, improved productivity etc. 

Hot dip galvanizing plants on the surface of Steel, Aluminum and Iron metal with zinc coating for long lasting and quality finishing by professionals as per the client's need and demand. Hot dip galvanizing plant used in the processing of galvanizing by our organization as Precimax online to deliver the solutions that's why we are appreciated by our clients and client’s positive feedback is our main asset.
