Product quality:
Pipe product of this unit meet with required standard.
Process flow:
Uncoiling→pinching& leveling→electric vertical roll→cutting& butt
welding→electric vertical roll→rotary shear→vertical roll→delivery
m/c→guide board→forming unit→inside welding→outside welding→flying
cutting→pulling out
process flow mentioned above is general arrangement of host
machine, which can be revised , such as to add pipe beveling
machine, pipe hydrotester, as well as NDT testing equipment to meet
with relative international standard.
Annual output:
to be designed as per user's requirement
After-sale service:
1 year's guarantee is available, offer technical guidance of
installation& commissioning at home& abroad.
Below is general layout of host machine and reference photos of
spiral pipe machine, including preparation area, pre-bnd guiding&
forming unit, as well as beveling and hydrostatic testing
equipment. Machinery in finishing area, such as pipe beveling
machine, hydrostatic testing machine is opptional.
