Described straight length afterbody outer wall is provided with a circle stop ring.
Described joint socket section comprises connection straight length, flared section, socket joint straight length and the loudspeaker inducer that order fuses, and the gradient of flared section is the 3-5 degree.
Described plastic winding structural wall tube is to twine the I-steel shape structured wall plastic tubing of making by plastics square tube spiral.
Described plastic winding structural wall tube is to mould compound T type band spiral by steel to twine the steel plastic composite structure wall plastic tube of making.
The utility model socket type plastic tube makes it compared with prior art owing to adopted above technological scheme, have following advantage and and characteristics:
1, socket type plastic tube of the present utility model can field fabrication, promptly plastic winding structural wall tube and the flared pipe fitting fusion weld of plastic material of the same race is integral the formation socket type plastic tube before the construction at the scene.Directly adopt socket type plastic tube to interconnect during construction, make tubing that preparatory work is installed in earlier stage and significantly reduce, dispensed behind the tube manufacture and the supporting process of tubing.
2, straight length adopts I-steel shape structured wall plastic tubing or steel plastic composite structure wall plastic tube to make, not only has good structural advantage, also can realize the same convenience of other moulding patterns mounting type easily, in tubing connection work progress, only the tubing socket joint need be coupled together and get final product, not only make things convenient for but also saved a large amount of installation times.
3, the flared part of joint socket section has the gradient of 3-5 degree, cooperates bimodal hydro-expansive rubber circle, can reach good sealing effect, also plays the effect of slip joint, remedies the longitudinal extension that uneven settlement and big load impact cause.
4, because average per two tubing have only an interface when connecting, so just significantly reduced the risk that seepage appears in the tubing joint.
5, solved the problem that the winding structure pipe can't online enlarging.
6, solved the not inconsistent problem of creep ratio rate simultaneously of tubing and pipe fitting material.
