SSAW Steel Pipe And Tube making machine For Large Pipe

The SSAW steel pipe making machine is also called HSAW steel pipe making machine,   it is applied to produce bigger diameter of steel pipes which applied for oil and gas pipeline systems, construction structure, water transport and sewage treatment, thermal industry, buildings etc. Our Pipe Mill production line can be designed suitable for manufacturing steel pipe up to API-5L, API-5CT, BS1387-85, ASTM and GB9711 Standards.  

The SSAW pipe diameter range is from 20 inch to 100 inch, 406 mm to 2540 mm.The we can get the different diameter of SSAW pipes with the same size of the steel strip, there is a wide application for the raw material steel strip, and welding seam should avoid the primary stress, good performances to bear the stress.

The SSAW pipes types manufactured by our tube making machine:

A typical SSAW pipe and tube making machiine consist of:
1. Coil Probe: steel coil into the production line, the first full board Ultrasonic Inspection
2. Leveling Milling: through anvil plate leveling machine so that the original curl, and then pass the two edges of steel-sided milling machine milling, so that up to the requirements of the plate width, plate edge parallel groove shape
3. Cut Type: steel production line along the outer edge of the coiled-coil tube
4. welding and cutting: the use of advanced technology for pre double submerged arc welding(dsaw) cutting inside from the foot of the welding specification welded steel pipe welded outside use, etc.
5. Visual inspection: some basic parameters by a professional technician check
6. ultrasonic flaw: the inner and outer sides of the base metal and weld seam 100% inspection
7. X-ray detection: internal and external welds 100% X-ray television industry checks, the use of image processing system ensures detection sensitivity
8. Pressure test: hydrostatic testingmachine by-root test steel pipe up to the standard requirements to ensure that the test pressure
9. Chamfer level: steel pipe inspection pipe end processing, up to the requirements of the pipe end beveling size
10. Check: X-rays and then subjected to ultrasonic testingand magnetic particle inspection conducted pipe end, check whether the deposit welding problems and defects in the pipe ends.
11. Oiled Marking: Qualified oiled steel pipe corrosion and in accordance with user requirements for marking.
