Description
Technical field
The present invention relates to steel pipe coating equipment technical field, particularly relate to a kind of pipe plastic coating air stove.
Background technology
Inside and outside plastic-coated steel, inside and outside plastic-coated steel is at steel pipe walls melt and dissolved layer of polyethylene (PE) resin, ethylene-propylene
The Organic substances such as acid copolymer (EAA), epoxy (EP) powder, nonpoisonous polypropylene (PP) or non-toxic polyvinyl chloride (PVC) and constitute
Composite steel-plastic tubing.Plastic-coated steel not only has the advantages such as the high intensity of steel pipe, easily connection, flow impact resistant, also overcomes
The shortcomings such as steel pipe is met that water is perishable, polluted, fouling and plastic tube intensity is the highest, fire-fighting poor performance.
Large-diameter steel pipe generally refers to the nozzle diameter steel pipe at 300mm～2400mm, can need coating according to different
The plastic coating of the various different performances such as polrvinyl chloride (PVC), polyethylene (PE), epoxy resin (EPOZY).To large-diameter steel pipe
Carry out plastic-coated, the transporting resistance of steel pipe can be reduced, improve flow and transfer efficiency, reduce discharge pressure loss.Heavy caliber applies
Steel pipe is widely used in the engineering fields such as tap water, natural gas, oil, chemical industry, medicine, communication, electric power, ocean.
Before steel pipe is carried out inside and outside plastic-coated, needing placing steel tubes to preheat in preheating furnace, China's utility model is special
Profit 202667106U discloses " a kind of epoxy resin plastic-coated steel heating furnace ".This kind of heating furnace include melt pit, hot blast drying tunnel and
Hot blast drying tunnel support that hot blast drying tunnel connects as one, plastic-coated steel conveyer device, and it is arranged on the flue on hot blast drying tunnel.
Although steel pipe can be heated to predetermined temperature by this kind of heating furnace, but owing to after fuel combustion heating steel pipe, easily makes steel pipe produce
Raw uneven temperature, even if the heat conduction velocity of steel pipe is very fast, it is also necessary to steel pipe to be heated to above temperature during plastic-coated, when
It drops to be only possible to during plastic-coated temperature form uniform temperature, so, this kind of mode of heating waste energy, also to steel tube surface simultaneously
Dirt can be produced.Topmost problem is, after utilizing this kind of heating furnace to heat steel pipe, it is necessary to taken after oven door opening by steel pipe
Go out, because taking out and place into the operation relative difficulty of steel pipe in high temperature furnace, be also required to longer even with plant equipment operation
Time, a large amount of losses of furnace heat can be caused.
Summary of the invention
The technical problem to be solved is: provide a kind of pipe plastic coating air stove, the programming rate of this air stove
