Description
Technical field
The invention belongs to the steel band reinforced polyethylene spiral ripple pipe technical field, particularly relate to a kind of steel band reinforced polyethylene spiral ripple pipe, and connection fittings and connecting means.
Technical background
Steel band reinforced polyethylene spiral ripple pipe is a kind of by Wrapping formed composite pipe, advantage such as the high rigidity of its integrated steel band and poly rotproofness, frictional resistance be low, resistance to wear, has very high ring stiffness, and integral forming technique is good, seam tensile strength and anti-corrosive properties height, the life-span is longer; Have multiple reliable, Placement easily.
At present, the connecting means of steel band reinforced polyethylene spiral ripple pipe mainly contains: hot melt is extruded welding, the Electric thermal smelting belt welding is connected with heat-shrinkable tube (band).
It is to adopt special-purpose hot blast to extrude soldering appliance that hot melt is extruded welding, earlier tubing is connected the two ends heating, and welding gun is extruded the polyethylene material of fusion, the polythene material fusion that connects the seam two ends is connected into the connecting means of one.
The Electric thermal smelting belt welding method is to utilize the high temperature connecting means of the electric heating element energising back generation that is embedded in the joint surface of contact, is to be rigidly connected.When Electric thermal smelting belt connects, must carry out in strict accordance with the technical order of Electric thermal smelting belt requirement and the programmed sequence of operations of equipment regulation.The Electric thermal smelting belt that adopts must be provided together by factory.
It is to adopt fiber reinforcement polyethylene shrink belt to do internal layer that heat-shrinkable tube (band) connects, and heat-shrinkable tube is done skin, and the heat-shrinkable tube internal surface scribbles hot melt adhesive, after heating and the connecting means that fuses of lock ring that adjacent pipe end is fitted.
The structures shape of steel band reinforced polyethylene spiral ripple pipe itself its both ends of the surface have dislocation, the structure of dislocation so existing Placement extremely bothers at work progress, mainly embodies as follows as shown in Figure 1:
1, pipe is placed trouble, under the rugged environment of building site, be tubing to good, to flat, the slit is the devil less than 10mm;
2, to be extremely unpractical in the welding of mismatch position with extruding welding gun, extrude welding gun for one and be worth several ten thousand yuan, unit in charge of construction can not be ready to invest to buy, generally can provide by pipe production producer,, producer generally also has tens to be to construction site up to a hundred, extrudes welding gun if each building site is joined one, and that input is to well imagine.
3, the mismatch position is artificial manual welding, if only weld the mismatch position, just very can seepage, and that is got only one week of tubing and all will weld, and is like this bothersome, trouble.
Summary of the invention
One of purpose of the present invention is to overcome the deficiencies in the prior art, and a kind of connection fittings that steel band reinforced polyethylene spiral ripple pipe connects of being convenient to are provided.
Two of purpose of the present invention is to provide a kind of steel band reinforced polyethylene spiral ripple pipe of being convenient to connect.
