Abstract

The high-strength plastic pipe is mainly made up of thermoplastic or thermosetting resin (55-80 Wt.%), filler (3-18 Wt.%) and natural or synthetic fibre (15-35 Wt.%) by moulding and is suitable for high- or middle-pressure pipeline. Its advantages include very highloading capability, better anticorrosion nature and firm adhesion.

Description

High pressure resistant highstrenghtpiston's tubing and pipe fitting and connecting means

The invention belongs to a kind of high pressure pipe line, particularly in a kind of high pressure resistant highstrenghtpiston's pipeline.

The existing pipeline that is widely used in building and the municipal engineering mainly is steel, iron pipe conduit and concrete duct.Such pipeline, not only investment is big, and transportation and install very difficult.The long-term use of steel, iron pipe conduit also exists the hidden danger of corrosion failure.At present, underground water pipe in many cities and gas pipe line etc. are because the long-term corrosion failure that causes that uses not only causes very big economic loss, but also causes bigger personal injury.

In some industry, though adopt plastic pipe as existing in the chemical engineering industry, because the thoroughly solution as yet of its connecting means or link, thereby can not effectively utilize, often leave hidden danger to keeping the safety in production.

The objective of the invention is to solve problems of the prior art, propose a kind of high pressure resistant highstrenghtpiston's tubing, it both had been applicable to the process pipe of various pressure, was applicable to the pipeline in building and the municipal engineering again.

Another object of the present invention is to match, propose a kind of high pressure resistant highstrenghtpiston's pipe fitting with high voltage bearing highstrenghtpiston's tubing.

A further object of the present invention is to propose the connecting means of a kind of high voltage bearing highstrenghtpiston's pipe and its pipe fitting.

High voltage bearing highstrenghtpiston's tubing of the present invention, it is mainly by thermoplastic resin or thermosetting resin, filler and natural fibre or synthetic fiber are compound or molded forms, and part by weight wherein is respectively 55-80%, 3-18% and 15-30%.The chemical component of described tubing is respectively the 60-80% PVC by its weight, 5-15% graphite and 15-25% glass fibre.The chemical component of described tubing is respectively the 55-75% polypropylene by its weight, 4-16% red soil or industrial residu and 20-30% carbon fiber or glass fibre.The chemical component of described tubing is respectively the 60-75% polystyrene by its weight, white carbon black of 3-10% or French chalk and 20-30% glass fibre and carbon fiber.It is alive or 40-70% is ceramic that the chemical component of described tubing is respectively the 30-60% carbon fiber by its weight.

High pressure resistant highstrenghtpiston's pipe fitting of the present invention, it mainly comprises adapter sleeve, elbow, threeway, four-way, return bend, end socket, CONCENTRIC REDUCER, elbow ozzle and mitered ozzle, there is straightway at the two ends that it is characterized in that described pipe fitting, and be provided with joint socket therein, its internal diameter is slightly larger than the external diameter of the pipe that two ends are attached thereto, accompany layer of adhesive between the inwall of tube outer wall in this joint socket and pipe fitting joint socket, described pipe fitting is to connect with one heart or eccentric the connection.Described elbow is the major diameter elbow, minor axis elbow or reducing elbow.Described threeway is three-dimensional threeway, double sweep tee or skew T.

The connecting means of the pipe at high pressure resistant highstrenghtpiston's pipe fitting of the present invention and its two ends is to be provided with joint socket at the two ends of connection pipe fitting, its internal diameter is slightly larger than the external diameter of the pipe that two ends are attached thereto, and tube end is inserted in the pipe fitting joint socket after the brushing layer of adhesive on the inwall of pipe fitting joint socket and pipe end outer wall respectively again.

High pressure resistant highstrenghtpiston's pipeline of the present invention, not only can be used in height, the middle compression technology pipeline, also be applicable to the upper and lower conduit road in industry and the civil building, gas pipe line, caliduct, and air-conditioning duct, and the underground water pipe in the municipal engineering, gas pipe line, oil-piping, hot duct and blow-off line etc.And removed fundamentally that the steel, iron pipe conduit of existing use and concrete duct exist from great, transportation and install very difficult, the corrosion failure that chemical mordants such as underground water, acid, alkali, salt, oil, dirt cause.Thereby not only reduced construction investment, but also improved the long-term safety use of tubing greatly.

The major advantage of the high pressure resistant highstrenghtpiston's pipeline of the present invention is that it has high bearing capacity, has good Corrosion Protection again, and is bonding firm, and aboundresources is with low cost, easy to manufacture, easy to use, and neat and artistic.

For the structure that further specifies high pressure resistant highstrenghtpiston's pipe fitting of the present invention and profile and with being connected of high pressure resistant High strength plastic pipe, be described with embodiment with reference to the accompanying drawings, its accompanying drawing has:

Fig. 1,2 is respectively the perspective and the sectional view of the adapter sleeve in the pipe fitting of the present invention;
