Description
Technical field
The present invention relates to a kind of tubing, especially one kind covering modeling band enhancing hollow spiral tube and its manufacturing method.
Background technology
Hollow spiral tube be it is a kind of with high density polyethylene (HDPE) (HDPE) for raw material, be made of hot winding shaping process
Structure-wall pipe material, a kind of novel acidproof, anti-corrosion of the tubing, resistance to compression, nontoxic environmentally protective tubing belong to environment-friendly and energy-efficient height
New Product is the optimal regeneration products such as pipe of cement, cast iron pipe, glass tube, PVC-U bellowss.HDPE is macromolecule
Polymer makes hollow spiral tube material have good flexibility and whole critical external compressive resistance ability, is used in the case where there is overweight load road surface
When, it is ensured that current safety.Since the flexibility of tubing can be by pipe when the geological activities such as earthquake, Earth cave occur
Road failure loss is reduced to minimum, improves the ability of public utility quake evaluation.Pipeline is molded using winding process, is saving material
Under the premise of material, the ring stiffness of tubing is improved.There is high density polyethylene (HDPE) extremely strong corrosion-resistant and chemically resistant material to corrode
Ability is significantly better than when conveying corrosive fluids or being laid in the extremely strong soil of corrosivity without any preservative treatment, performance
Other tubing.It due to its excellent ageing-resistant performance, is used as buried pipeline, it can be ensured that 50 years service life.High density
Polyethylene winding structure wall pipe is not added with any auxiliary agent in process, 100% using high density polyethylene (HDPE) without any toxicity,
Non-scaling does not breed microorganism.Cooling water circulation uses product in process of production, and environmentally safe object generates, the same to trade mark
Waste and old pipeline can 100% recycling.Hollow spiral tube material inner wall roughness N is about 0.010, therefore ratio when trandfer fluid
Frictional resistance is small, and carrying capacity can be increased substantially compared with pipe of cement under same use condition.Therefore the smaller hollow wall of available internal diameter twines
The larger pipe of cement of internal diameter is substituted around pipe, reduces project cost.Inside pipe wall roughness is low, and carrying capacity is big, in the application, same item
It will all be improved compared with traditional piping material using the reliability of hollow spiral tube engineering under part, comprehensive benefit is apparent, especially exists
Construction site is narrow, building dense, underground utilities are complicated and heavy traffic section and when acid-base property soil is laid with, more excellent
More property.
Since there are hollow wound pipe many excellent performances, the tubing to be suitable for conveying coolant-temperature gage in 45 DEG C of municipal administrations below
Draining, building outdoor drainage, the defeated draining in buried farmland, discharge of industrial wastes, road drainage, sewage treatment plant, sports ground Plaza Project

A kind of HDPE, PVC plastic plastic composite winding pipe, including rectangle hollow band and HDPE plastic obturator are constituted, the rectangle
The tube wall of hollow belt is the PVC plastic bed of material, composite tack coat and HDPE plastic layer respectively from inside to outside, uses multilayer complexity
Structure, it is perhaps with good performance, but production and processing technology difficulty necessarily increases, and multilayer labyrinth is unfavorable for ensureing
The quality of production.For another example application No. is 201210192872.3 Chinese patents to disclose a kind of fiberglass reinforced HDPE Dual-wall windings
Pipe, the hollow square tube squeezed out after being mixed with long glass fibres by HDPE raw materials are wound, and mainly squeeze out the improvement of raw material, but
The mixing of glass fibre and plastics, uniformity are difficult to ensure, and tube wall smoothness is necessarily affected when extrusion.For another example apply
Number a kind of fiberglass reinforced hollow wall polyethylene wound pipe is disclosed for the Chinese patent of 201310001048.X, is twined by hollow square tube
Around formation, but is synchronized when hot melt adhesive is welded and be wound with an at least PP/PE compound coating roving glass fiber beam；By reinforcing glass fiber
