Manufacturing Process
The manufacturing process for welded and drawn tubing initiates with a cold-rolled sheet or strip produced in coils. The coils strips are shaped into a tube form and subjected to welding, where a fusion juncture is created by melting the edges of the open seam without the use of filler material or flux. Cold drawing follows, involving pulling the tubing through a die to attain the desired size while maintaining a uniform wall thickness. The cold drawing process is repeated, and to prevent a reduction in ductility, the tubing is annealed between drawing operations. The welded area, despite being detectable only through etching or microscopic examination, becomes homogeneous with the parent metal. Finally, the fine tubes undergo bright annealing in specialized furnaces imported from Japan, relieving stresses and maintaining corrosion resistance by preventing oxidation and loss of chromium. The advantages of this process include precise thickness control, visual detection of surface defects before welding, and cost-effectiveness compared to seamless tubing.

Tube Forming & Tig Welding Machine
The grade and application parameters determine the process of tube welding and forming. TIG welding is the method used by Arya Tubes, and it's perfect for fabricating small-diameter tubes. After entering a welding machine, steel sheets are coiled and fused together. The steel sheets are shaped into a coil as they enter the machine. To create a tube, these coils are then fused together at the seam.

Cold Drawing Operation
The Drawing table is designed to draw the in-process S S Tubes by applying imported diamond Die, Plugs and highly quality coolant to get the required sizes for further process. This process allows the S S Tubes into a different diameter, wall thickness and inner diameter.

Bright Annealing Furnace
Heating metal above the point of re-crystallization and then bringing it back down to room temperature is known as annealing. The metal is processed through annealing equipment in order to regain its required hardness and brightness. Metal becomes soften as a result of that the process of drawing and straightening cut becomes convenient.

Straightening Machine For Final Products
For large, small & thin diameter SS tubes, the cutting and straightening processes are crucial. This involves inserting tubes into a barrel, passing them through extremely precise rolling rollers to straighten the tubes or pipes, and then cutting them into the required lengths or according to bespoke specifications or customized length.

In House Testing Facilities
We have established a fully functional in-house quality inspection lab to test and measure the quality of both in-process and finished products. This is done to ensure that the products are of the highest quality assurance and to comply with the guidelines of ISO 9626:2015 regulations for production and quality management system.
