Description
Technical field
The present invention relates generally to a kind of tubing, relates in particular to a kind of double wall corrugated high-density polyethylene pipes.
Background technology
Pvc pipe (UPVC pipe) hard polvinyl choride pipe, is to use pressure sintering extrusion molding after being coordinated with stablizer, lubricant etc. by polyvinyl chloride (PVC) RESINS, is the plastic pipe being developed and applied the earliest.UPVC pipe resistance to corrosion is strong, it is bonding to be easy to, price is low, quality is hard, but owing to having UPVC monomer and additive exudation, is only applicable in water feeding system that delivery temperature is no more than 45 ℃.Plastic conduit is for delivery of tap water, waste water, chemical, heating fluid and cooling fluid, food, ultrarapture liquid, mud, gas, the application of pressurized air and vacuum system.
PE pipe has medium-density polyethylene pipe and high density polyethylene pipe.The former is applicable to carry artificial coal gas, Sweet natural gas, the liquefied petroleum gas (LPG) of gaseous state, and the latter is mainly for delivery of Sweet natural gas.With steel pipe comparison, construction technology is simple, has certain snappiness, and main is to be not used as rotproofing, will save a large amount of operations.Shortcoming is with regard to apparatus not as steel pipe, and the special safe spacing of noting heating power heating in construction, and can not being exposed in air under sunlight, and responsive to chemical substance, prevents that the leakage of sewer line from damaging.
