How is the 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.

Stainless steel rectangular / square
Currently, Dai Duong Stainless Steel Tubing Products has been confirmed as the leading stainless steel pipe products of Vietnam market, is the quality and prestige product and was certified by the trust of whole customers in Vietnam. Stainless steel pipe products manufactured by Dai Duong export to Europe, Asia, such as Turkey, India, Malaysia, Indonesia, Brazil …

The products and clearly subtitling:

DAI DUONG will explain specific 3 products round stainless steel pipe & square & rectangular stainless steel pipe with different common surfaces.

1/ Strip roll:

The tape is small in size 2B surface, which has good ribbon quality, and is produced from imported raw material rolls made through the discharge process.

Material Roll 2B-> Ice Conditioner-> Fiber tape.

2/ Round pipe 2B/ square pipe 2B/ rectangular pipe 2B:

the finished 2B welded pipe product, which is produced by the shape rolling process with the original material is 2B surface fiber.

Fiber Tape – 2B-> Bench shape – > Weld Tig-> Grinding line weld-> Roll-up-> Cutting scale-> packing.

3/ Round pipe 500#/ square pipe 500#/ rectangular pipe 500#:

A welded pipe product with the surface finish 500#, which is produced from pipe – 2B through polishing process). Depending on the surface quality of the tube’s 2B head to press a piece or two of the roughness and particle of the roughness simultaneously to press the type of the declaration accordingly.

Tubing – 2B-> sanding-> Proclaim oil-> Common proclaim-> announced hard canvas-> Daddy soft cloth-> packaging
