1.1 General information
This equipment is specially used for producingΦ19-Φ76mm,δ0.7-3.0 mm
high-frequency straight seam welded pipe and corresponding square
pipe and special-shaped pipe. The composition of equipment is from
decoiler to fixed length cutting saw. Rolling speed can be adjusted
correspondingly within suitable range of pipe diameter and wall
thickness.
1.2 Applicable material
(1) Hot, cold-rolled steel strip and galvanized (As per GB700-88 or
GB1591-88)
(2) Material: Low-carbon steel, low alloy steelδs≤345Mpa,δb≤610Mpa

1.4 General process
Raw material (steel coil) → decoiling→ shearing and welding→
accumulator → non-power leveling →forming milling →high frequency
welding →de-burr frame→ cooling unit→ sizing unit →rough
straightening → fixed length cutting →run out table

Quality Assurance
we Shall be responsilbe for quality problem resulted from design
and manufacture with one year after successfull installation and
debugging and all the expenses for replacing parts and components(
exclude human factors and vulerable components ) shall be born by
us !
Debugging
1) Factory will send 1-2technical engineers for installation and
testing operation
2) The site, the equipment foundation, cool constructions etc.
responsible by buyer according to equipment material which provides
by supplier, the equipment for installation (lift equipment, tool
etc.), the installation accessory material (wire, drive pipe, water
pipe and so on), the labor force arranged by the buyer.
3) The buyer is responsible for power supply, water supply and gas
supply to the equipment interface connector
4) Buyer Preparation Notes
(a)Machinery device takes the location (length* width)
(b)Power supply: Main power to equipment control bench, unit
position
(c) Air feed: Air compressor (1.5 cubic meters/minutes
(d) Water supply: Water source to machine station
