How is the weld stainless steel pipe produced

1. Splitting :

Splitting rolls with bigger sizes into rolls with smaller sizes according to each size tubes or to customer’s requirements rolled through the tape discharge system.

This stage requires precision in terms of the size belonging to the tape according to the given thickness and requires the quality to meet the standards required by the pipe roll.

Slitting is also a process of quality inspection of input materials for supplier feedback base and noting to the following stages in order to produce the best quality products, reducing error products during production process.

2. Rolling to form shape:

The original material is the tape that is slowly swept up (round-go) and pair the eyelid together before welding through the go mold and eyelid system.

The level of the two-sided eyelid graft is as precise as the quality and stability of the welding line.

3. TIG welding:

The stage is the use of volume of heat generated from the line power supply (270-280 A) for melting Inox to create a binder between the two eyelids, simultaneously using Nitor gas and Argon gas to protect the welding needle and to clean the weld line. In this case

Argon Gas has amain mission of protective effect on welding needles.

Nito Gas has the effect of blowing the impurities formed in the welding process, cleaning the weld line and increasing the reformation of the weld.

4. Welding line grinding:

The weld line grinding is the grinding process of the raw welding line that is formed after welding. This stage is applied with the types of sanding to break and to polish the weld line

5. Orthopedic Bench:

The shape of the tube, which includes the format mold pairs for the pipe is round evenly, creating the standard diameter size and straightening mold making the pipe as straight as desired. For square tube, the box before crossing the straightening mold is also shaped rectangular or square.

6. Cutting tubes:

the cutting phase of pipe to a certain length. The tube is cut with a taper or cut with a knife, for the cutting tube with a bevel machine for the product with the quality cut, no base left in order not to trim the pipe head. For tubing is made by knife cutter. After cutting process leaving many bases, the product needs cutting back to the top by sanding machine system or handheld machine.

7. Polishing stage:

the stage consists of a wide range of detailed stages (sanding->-oil-> proclaiming often-> hard-to-> The soft-cloth claims). Depending on the type of square pipe, rectangular or round tube, the surface quality of the product and the quality of the input material on which we arranged each different paragraphs.

8. The packaging:

This process is done up to the request of the customer or in accordance with the quality standards of the company for the purpose of preserving, sorting and creating images for the product, and having the basis of traceability of the product in the process of warehousing and the customer’s place.
