5. Forming & Sizing Mill

 

Forming & Sizing Mill adopts roller type forming principle and high-frequency induction welding. The strip is fed into the forming machine by the feeding device in the mill and the forming roller continuously rotate and press the strip into the required shape. Due to the skin and the kindred effect, the high-frequency current is concentrated on the weld joint that is heated rapidly and reaches the welding temperature. The tube seam is welded under the pressure of squeeze rollers. The finished welded tube with required size can obtained after the cooling, sizing and primary straightening.

Technical scheme and quotation of Φ50~Φ101.6mm four-station hydraulic press

1.  Overview;

The equipment is arranged in the finishing part of the straight seam steel pipe production line, and is used for water pressure test of the straight seam welded steel pipe. The technical level meets the requirements of the ASTM standard for steel pipe hydrostatic test.

2. Technical parameters:

Diameter range of test steel pipe: Φ50~Φ101.6mm

Length of test steel pipe: 4~6 meters

Test steel pipe material: low and medium carbon steel

Maximum test pressure of steel pipe: 5MPa (50bars)

Holding pressure time (can be set): 2~5sec

Number of roots per test (four stations): 4 roots

Sealing form: radial seal

Pressure test medium: emulsion/water

Low-pressure water filling method: pre-filled water

Pressurization method: pressurization cylinder pressurization

Equipment installed capacity: ≈90KW

Efficiency (holding pressure 5S): The maximum production rate is 12 pieces/min (1/2″ pipe), but the air supply pressure from the air compressor to the equipment shall not be lower than 0.6Mpa;

2. Work flow:

Upper pipe → align → chain transport to the water pressure center → clamp → fixed and mobile end test head extends to seal both ends of the steel pipe → low-pressure water fills with water, exhausts → closes the water filling valve and exhaust valve → pressurizes → protects Pressure→Relieve pressure→Retract the fixed and mobile end test head→Clamp to loosen→The chain sends out the steel pipe→The water is empty→The material is discharged

3. Equipment performance:

The pressure test machine designed and developed by our company has three processes: inner wall flushing, pressure test center, and air water device; the pressure test machine is a four-station pressure test system, horizontal, two experimental seat structure, chain conveying in and out.

3.1. Flushing system: includes alignment and flushing functions; the pipe fittings are transferred from the feeding platform to the alignment roller table by the transfer mechanism, and a low-pressure centrifugal pump extracts industrial fresh water, which is connected to four stations through various valve pipelines for flushing Head, clean up the impurities in the steel pipe before starting to suppress, to prevent the remaining impurities in the steel pipe from damaging the seals on the equipment;

3.2. Four-station fixed and mobile test seat: when the pipe fittings are tested for pressure, the pipe fittings are sealed by the sealing device (using radial seal) on the test seat, and the low-pressure water filling valve, exhaust valve and high-pressure control valve controlled by the four-station are opened. Or close to realize the pressure test function;

3.3. Sealing test head: It adopts polyurethane radial seal, and replaces the corresponding sealing device according to different specifications;

3.4. Clamping device: consists of two sets of pneumatic clamping; cylinder-driven automatic centering clamping, replacing the center block to adapt to different specifications of steel pipes;

3.5. Chain conveyor: It is used to transport the pipe from the waiting material rack after washing to the pressure test center position, and send the steel pipe after pressure test out of the working position. A chain device driven by a cycloid reducer is used to pass through the chain. The claw realizes the positioning of the steel pipe;

3.6. Low-pressure water filling: The combination of low-pressure centrifugal pump and air pressure water storage tank is used for pre-filling, and the pressure test tube is quickly filled and exhausted when working;

3.7. High-pressure water injection: using a combination of booster cylinders and pipeline accessories to achieve four-station booster;

3.8. Water emptying device: use cylinder lifting to empty the pipe fittings after pressure test
