Product Description

Stainless Steel Welded Pipe Mill 

The plate in certain width after slitting line and stripping is unfolded and leveled. Then, they are sent into forming machine. Used the roller, the plate is bent into pipe state. The edge of the steel plate is melted by making use of the proximity effect and skin effect of high frequency current. Then, the plate is extruded and welded into the pipe by extruding roller. Straight seam welded pipe mill also is called ERW mill.

The forming styles of straight seam welded pipe can be divided into roll forming, flexible forming, full auto flexible forming. The mill developed by our company adopts roll forming when having small diameter (Φ≤114). Flexible forming or full automatic flexible forming is adopted when having middle or large diameter(Φ≤711).

In recent year, our company developed the precise control forming. The advantage of this kind forming is to guarantee the excellent forming quality in rough forming section through the precise control. Then it is no need to have the repair management in precise forming section. Therefore, the precise forming in this forming method does not need to change the roller. All the forming section does not need to change the roller, which solves the problem of the change in precise forming section and non-change in rough forming section. Therefore, it saves the roller investment and decreases the time of roller changing. Besides, during the diameter changing, all are controlled by industrial computer. The roller will automatically reach the position by inputting the pipe diameter, pipe wall thickness, material and other parameters. It largely improves the mill efficiency and pipe qualified rate. This forming method is suitable for medium and large mill from 219mm to 711mm, which saves the investment and improves the efficiency.

According to the pipe application, the ERW line can be divided to API standard pipe mill and national standard mill.

API standard straight seam HF welded pipe mill introduction is mainly used for producing the high grade pipe such as oil, gas delivering and casing pipe in the oil well. These high grade pipes strictly require the pipe material and pipe quality. This kind of straight seam HF welded pipe mill has IF annealing, air cooling roller rail, UT detector, high pressure hydrotester, diameter drifter and other detect equipments and art craft.

National standard mill is mainly used for manufacturing the low pressure fluid pipe and structure pipe.


Our company designs and manufactures the Φ273-Φ630x16mm stainless pipe welding mill for Yingkou Pipe Company. This machine adopts the newest technology in our company, flexible forming, and automatic diameter changing adjustment. In rough forming section, it is no need to change the roller. It only needs to input the pipe diameter, wall thickness, material and other parameters. Then, the roller will automatically reach to the right position to start the production directly. Fine forming and sizing section adopt quick roller changing technology. These two newest technologies make the diameter changing to be one to two hours.

Installation and Commissioning

The seller provides on-site installation and guidance services. The seller's visas, round-trip airfare, meals, and accommodation are the responsibility of the buyer, and the seller's staff will pay USD 100 per person per day.

Term of Payment

Within 7 days after the contract is signed, 30% of the total amount of the contract will be prepaid, and the contract will take effect; 
the contract will be effective for two months, paying 20% of the progress payment; before delivery, 45% of the total contract amount will be paid. 5% will be paid when Finished installation and commission.

Training

The training is carried out in 3 steps.
Step 1: During the installation process, the seller's technicians will train the buyer's personnel on the structure, principle, maintenance, maintenance, operation, etc. of the equipment.
Step 2: After the test run, the seller's technicians will conduct 10 days of intensive training for the buyer's personnel until the buyer's personnel are fully capable of operating the equipment.
Step 3: For special types of work, because it is difficult to short-term training, the seller can help introduce two forming workers and welding workers, working in the buyer's unit until the buyer's personnel are skilled in the technology. The wages of the two skilled workers introduced by the seller are paid directly to the buyer monthly by the buyer.

Quality assurance:

The unit equipment is provided with a one-year quality guarantee period, and the seller is responsible for non-human damage during the warranty period. Wearing parts and consumables are excluded.

Project cycle

The design and production cycle of the project is 6 months, and installation and commissioning are 1.5 months.
