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.

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.

Other manufacturers of bending pipe winding 3PE anti-corrosion production lines, some processing range between Φ630-820mm, must have manual assistance on the line, flame secondary baking, PE strip has warped edge, low production efficiency; Although some processing range sheath to Φ630-1220mm between, but need to use bending waste heat for winding operation, the use of rotary center type push head, replacement of pipe diameter is complicated, push head cantilever is too long walking instability; Although some use mechanical electrostatic spraying, a high degree of automation, but the range of machined pipe diameter is really small, can only be between Φ300-800mm. The pros and cons are obvious.

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.
