| Size | OD:3.18-101.6mm |
| WT:0.5-20mm |
| Length:Max.12M |
| Advantage | Superior surface finish ,better mechanical property; more precise
dimension; perfect inspection method and inspection equipment |
| Application | Boiler tube applies to petroleum,chemical industry,electric
power,boiler,high temperature resistant,low temperature resistant,corrosion resistant.The size
can be made according to the customers requirements.High pressure boiler pipe applies to
container,petrochemical and so on.Note:Generally,high pressure boiler pipe’s working
pressure above 9.88Mpa and working temperature between 450 to 650. |
| Package | Plastic in both ends, then packed in iron case |
Process :
1 . We use Cold Drawn techonology to produce U bend tube
2 . U bend tubes produce will accordance to customer's drawings
3 . To avoid oxidation , inert gas (Argon) is passed through tubes
ID at the required flow rate
4 . The radius is checked for its OD and wall thinning with the
recommended specification
5 . We'll choose three different position or as customer's require
to make sure tubes quality . We'll do physical properties and
micro-structure test
6 . Visual inspection for waviness and cracks is done with Dye
Penetrant Test
7 . Each tube is then hydro tested at the recommended pressure to
check for leakage
| Application | a) Petroleum , chemical enterprise , super heater of boiler and
heat exchanger |
| b) High temperature-resistant transmission fluid pipe in power
station |
| c) Ship with pressure pipe |
| d) Exhaust purification device |
| e) Construction and ornament |
| f) solar industry , military , semiconductor etc |
