The underground steel strip reinforced polyethylene (PE) spiral corrugated pipe for sewage disposal is supported by a bent and molded steel strip waveform structure which is applied with high-performance adhesive rein on surface, and wound, extruded and compounded into a whole on production line.
This piping system is connected by hot melting welding, heat-shrinkable pipe (band) or electric melting band, etc., adapts to needs of various different works and operating conditions and meets the requirements of reliable sealing and easy connection better. The pipe has a wide application prospect and is the preferred alternative to traditional large-diameter drainage pipe.
Strong corrosion resistance: the pipe is made from anti-corrosive PE material, so it will not be corroded by acid, alkali or oil content, etc. in sewage or waste water.
Strong resistance to external impacts: the product is a flexible pipe and will return to its original shape when it suffers from external impacts. And, its excellent performance ensures that it is not easy to be broken in low degree settlement.
Strong ageing resistance: the pipe, owning to properties of its base material, can be used for 50 years or longer at 20 Celsius system.
Good low temperature resistance: the pipe will not be damaged by freezing or leak water even under minus 60 Celsius system.
Light weight: mass of the pipe is only 1/8 of the concrete pipe of the same specification and 2/3 of traditional spiral plastic structure pipe, so it can be transported and constructed conveniently without any large-scale construction equipment.
Easy connection: the connection has several modes and is simple and can be easily and rapidly executed on site.
Easy construction and low cost: the pipe is characterized by light weight and easy connection and does not have high requirements for excavation works. During urban water drainage engineering construction, it would save a lot of time and cost.
Superior wear resistance: the smooth inner wall and low frictional coefficient of the pipe determine its transport capacity of medium is high.
Good environment-friendly performance: the polyethylene itself is a non-toxic and recyclable material, so the pipe will not pollute the environment.
