Automatic steel pipe bends fittings 3LPE coating line
is an advanced solution to apply 3LPE/FBE external coating on steel
pipe bends, which are widely used in pipeline systems for the transmission of oil,
gas, water and other fluids.They have highly resistance to
corrosive from chemicals, moisture, harmful environment etc.
Winding anticorrosive steel pipe parameters
Diameter of steel pipe: 426, 630, 720, 820
Curvature radius: 4-6 times D
Elbow angle: 15-90 degrees.
Steel tube wall thickness: 8 mm -12 mm
Epoxy powder thickness: greater than 170 um

Russian SPV Steel pipe company, originally a steel pipe only
business, because the Russian market has a large number of
anti-corrosion steel pipe demand, they decided to invest in the
construction of a production line for pipeline anti-corrosion.
After signing the order with Walstad last year, Walstad prepared
its production equipment for shipment according to the schedule
requirements.

Our Services
3LPE coating processing line Quality guarantee period:12 months or 14 months from date of Bill of Lading.
During this period, the seller will provide free service for all
problems caused by quality of equipments, however except the
problems caused by the buyer .because of wrong operation.
Service:The seller would send technician to the buyer's factory to test the
new machine and train people of the buyer. The buyer should pay for
round-trip transportation expense, food, accommodation, insurance
locally and related salary.
The traditional 3pe anti-corrosion production line generally has
three forms, whether it is the double-layer epoxy powder Ownchart
operation method, or the manual heating installation method of
polyethylene heat shrink sleeve, there are obvious defects to a
certain extent. How to avoid all the above defects has become the
direction of technological development, and it is the purpose of
achieving high-quality anticorrosion in the real sense.
