Stainless steel plate products sales materials are:  SUS201, 202, 304, 316L, 316Ti, 321, 304L, 441, 444, 436, 439, 430, 409L, 410s, 309s, 310S, 904L , 2205, 2507 and other stainless steel materials, products are mainly used in chemical equipment, water treatment equipment, elevators, tableware, kitchen equipment, solar water heater, mechanical equipment, pressure vessels and other industries. Special processing: according to customer's specified open size.  

The company specializes in the production of all kinds of 316L stainless steel round tube, square tube, rectangular tube, 304 stainless steel tube, thick tube, mirror tube, 201 stainless steel quality pipe, high copper tube;  The company also undertake various stainless steel special-shaped pipe production, such as stainless steel conical pipe, groove pipe, stainless steel oval pipe, flat elliptic pipe, stainless steel arch pipe, D-shaped pipe, triangular pipe and so on  

Stainless steel pipe production process

1.  The raw materials  

To large steel mills such as Baosteel, Southwest, Tisco, Jisco, Wisco, Dingxin, Baoxin, Zhangpu procurement of raw material coil.  

2.  Pickling, passivation  

In stainless steel pickling passivation at the same time can remove the workpiece surface of oil, rust, welding spot, oxide layer, free iron and other dirt, after the treatment of the surface into uniform silver white;  At the same time, high efficiency corrosion inhibitor and fog suppressant were added to prevent the occurrence of metal corrosion and hydrogen embrittleness and inhibit the generation of acid fog.  

3.  rolling  

Stainless steel calendering process is mainly to roll the large plate into the corresponding thickness and width, to meet the needs of different customers, making the production more flexible, reduce the generation of waste.  

4.  annealing  

A metal heat treatment process in which the workpiece is heated to a predetermined temperature, held for a certain period of time and then cooled slowly.  The purpose of annealing is to: (1) improve or eliminate steel in casting, forging, rolling and welding process caused by a variety of organizational defects and residual stress, to prevent workpiece deformation, cracking.  ② Soften the workpiece for cutting.  ③ Refine the grain and improve the structure to improve the mechanical properties of the workpiece.  (4) Prepare for the final heat treatment and pipe making  

5.  Article points  

Stainless steel plate roll strip is the stainless steel plate roll, cut into the corresponding width, so as to carry out further processing and pipe, the process of strip should pay attention to the knife on the plate roll scratch, strip width and error, in addition to the strip is related to the pipe process, strip cape and burr for pipe making process is crucial.  

6.  roll  

Roll the divided stainless steel belt into a coil, and seal it with iron sheet for the next step of transportation.  

7.  welding  

Stainless steel welded pipe is an important process, stainless steel is mainly used arc welding and plasma welding, arc welding protection gas is pure gas, mainly welding stainless steel pipe below 3mm, plasma welding has strong penetration, mainly welding 5-8mm stainless steel pipe.  

8.  Bead polishing  

In the process of stainless steel pipe welding, the need for the appearance of the bead on the corresponding polishing and water cooling treatment, for the weld first for water cooling, directly with water mill grinding bead to level off, generally according to the thickness of stainless steel pipe to add 3-5 groups of water mill, bead grinding and dressing  

9.  plastic  

The process of stainless steel welded pipe is called extrusion production, all square and rectangular pipes, are originally from the round pipe, through the production of the same circumference of the round pipe and then extrusion into the corresponding square and rectangular pipe, after the mold shaping and straightened  

10.  cutting  

The cutting process of stainless steel pipe is relatively rough. Most of them are cut by grinding wheel. After cutting, the cloak will be produced, which needs further dressing.  In addition to a band saw cutting, the accuracy is relatively good, also exists cape  

11.  Heat treatment  

For special purpose tubes, bright heat treatment is needed to make the tubes reach a higher level of ductility 

12.  correct  

After the production of a few pipe roundness and symmetry slightly poor, need to re-use the die extrusion, make it symmetrical  

13.  straightening  

The problem often occurs in stainless steel welded pipe is that the pipe has the phenomenon of bending, there are many reasons for this phenomenon, the basic treatment method is directly re machine, plastic correction  

14.  Repair the end  

Due to the insufficiency of the cutting process, there are many burrs in the stainless steel tube mouth, and it is necessary to use the flat mouth machine for the bottle mouth and corneal machine to correct the port  

15.  pickling  

For industrial and mechanical pipes, an additional pickling process is required to passivate the surface and form a new protective film.  

16.  polishing  

The usual product tube and decorative tube for the surface treatment has several processes, polishing, divided into 400#, 600#, 800#, and pull sand is divided into round sand and straight sand, 180#, 240#, 400#, 600#, 800#, respectively for different levels of customer needs  

17.  inspection  

Inspection, mainly to check whether the outside diameter and thickness of the pipe is up to standard, whether the surface treatment is up to standard, whether the welding process is up to standard  

18.  packaging  

Stainless steel tube packaging, the current general is to use plastic bag packaging, for the surface requirements are strict, you can choose to use sponge packaging, bubble bag packaging, woven bag packaging and other packaging process  

Features

The inner wall of the pipe is smooth. It has low water resistance and can withstand high water velocity erosion.  After solution treatment, the welding pass and basic machinery, the product through "inner leveling", "bright annealing", "pickling", "inner polishing" finishing treatment, the appearance is bright, the inner wall is smooth, no corrosion, no scaling, pipe weld level, can be expanded, deep stamping, bending pipe no crack, no deformation and so on.  

1. Material surface: pickling surface, bright, no sand holes, no cracks and no pitting  

2. Implementation standards : American ASME/ANSI, Japanese JIS, German DIN and EU EN standards  

3. Embryo material country : domestic Qingshan Holdings, Baofeng, Shanxi Taiyuan Iron and Steel, Ningbo Baosteel and other large steel mills, good manufacturing: I plant pipe workmanship fine and rigorous, square pipe four corners average, flat without mold imprint, no black line, the roundness of the pipe can be controlled plus or minus 3 C.  

4. The raw material beautiful: the use of 304 (8 nickel 18 chromium) plate, high copper and high nickel 201 plate, imported 316L raw material, no peeling, less troma, plate flexibility, bright surface gloss.  

5. Cost saving: because: good manufacturing, beautiful raw materials, so you in the product deep processing process, grinding head, cloth wheel, wax, electricity, labor will save costs.
