Description
Technical field
The thermoplastic pipe that the present invention relates to strengthen, the particularly thermoplastic composite plastic tube of fast demountable.
Background technique
Thermoplastic composite plastic tube since the nineties in last century abroad oil gas field progressively use, begin at home oil gas field the beginning of this century on probation, be mainly used in oil-gas gathering and transportation, water filling and notes alcohol.Now, the thermoplastic composite plastic tube application comprises ocean flexible pipe, hot spring delivery pipe; Oil, product oil, natural gas transport; Municipal administration plumbing, oily water, desalination of sea water; Mine water supply, air feed, draining, coal washing water, coal dust are carried; Chemical plant, steel mill's corrosive liquids are carried.
Composite pipe generally comprises three-decker: the inside liner of internal layer, middle enhancement layer, and outer field external protection.As the enhancement layer in mesosphere, can be formed by inorfil, organic fiber or steel fiber as required.As inside liner or the outer field external protection of internal layer, generally formed by elastomer (such as vulcanized rubber, thermoplastic elastomer (TPE)) or plastics (such as thermosetting plastics, thermoplastic).If the internal layer of composite pipe and skin all are thermoplastics, then this composite pipe is called as thermoplastic composite plastic tube.
Particularly, as the inside liner of internal layer, can be formed by high density polyethylene (HDPE) (HDPE), crosslinked polyethylene (PEX), ultra-high molecular weight polyethylene (UHMWPE), nylon (PA) and polyvinylidene fluoride (PVDF) etc.
As the enhancement layer in mesosphere, can mention such as organic fiber (such as aramid fiber, polyester fibre), inorfil (such as glass fibre, carbon fiber, basalt fibre) and steel fiber (such as steel wire) etc.
For the thermoplastic pipe of emergent delivering fuel etc., particularly importantly it has high on-the-spot dismounting performance, namely can connect fast and dismantle at the construction field (site).For with the thermoplastic pipe quick mounting, for the joint that is used for connecting and the Placement of joint and pipeline requirement is arranged.
At present, the common mode that is used for the thermoplastic pipe connection comprises following three kinds: (1) welding, for example hot melt connection, electric smelting connection or electric smelting-hot melt connect, and use the melting joint between two thermoplastic pipes, and it is lower that the joint that this Placement forms bears pressure; (2) withhold connection, the socket end of a metal pipe element is inserted the reinforced thermoplastics pipe, at metallic sheath of reinforced thermoplastics pipe overcoat, with mechanical means metallic sheath-reinforced thermoplastics pipe pipe end-tube spigot side pressure is tightly become joint, this Placement often can cause the connecting part internal diameter less than the thermoplastic pipe internal diameter at other positions, thereby the liquid resistance that causes carrying increases, and how to guarantee to seal and bear higher axial and radial load simultaneously also different; (3) clip directly is socketed, and outside, two connecting parts is provided with draw-in groove, directly is sheathed on the draw-in groove place by clip and connects, and shortcoming is that the clamp band type connector construction is long, weight is large, connecting bolt is many, can not the mechanization laying etc., relatively is fit to low pressure line and uses.
In addition, for above-mentioned Placement, also exist joint to connect the problems such as solidness is not high enough, installation rate is not fast.
