Description
Technical field
The present invention relates to a kind of tubing and attaching method thereof, specifically a kind of high anticorrosion antiwear composite pipe and attaching method thereof.
Background technique
Along with the progress of science and technology and the development of economic construction, China has built a lot of emerging industry, particularly there is a lot of industry all relevant to industrial chemicals, the conveying of these chemical mediators just requires that namely tubing possess higher antiseptic power, possesses again certain wear-resisting property simultaneously, how can design and a kind ofly namely to possess higher antiseptic power, the composite pipe simultaneously possessing again high strength and wear resistance has been the problem of pendulum in face of the producer, this is also directly connected to follow-up safety in production and the working life of equipment, particularly be related to the every field such as environmental protection and transport.
The material of current corrosion-resistant field all has monotony, and its intensity of material that antiseptic property is good is not fine, the material that intensity is good, and antiseptic effect is not good again.Scientific and technical personnel take many thoughts in this field for many years, but some composite materials worked out still can not meet the needs of anticorrosion aspect.
Claimant is through in many ways consulting anticorrosion data, research find burn into cost that composite material that polytetrafluoroethylmaterial material and glass fibre reinforced plastics are formed can resist nearly all chemical mediator again low, intensity is high, the life-span is long, using scope is wide, quality is light, be convenient to installation and transport.
In recent years, the connection of some anticorrosion tubing is the problem of puzzlement chemical mediator conveying always, connects bad, easily reveals, cause the pollution of environment and the injury for human body, and also impact is normal simultaneously produces.
Summary of the invention
The object of the invention is to provide a kind of simple and reasonable, connecting means is simple and convenient, and favorable anti-corrosion effect, cost are low, intensity is high, the life-span is long, and using scope is wide, quality is light, be convenient to installation and high anticorrosion antiwear composite pipe of transporting and attaching method thereof.
The object of the present invention is achieved like this, this composite pipe comprises the body be made up of polytetrafluoroethylmaterial material internal layer, middle reinforcement layer and glass fibre reinforced plastics external protection, plug connector, opposite opened fastening piece, described plug connector is made up of spacer flanger and the bayonet end being arranged on spacer flanger both sides, plug connector axially with through hole, with attachment hole on spacer flanger; Described opposite opened fastening piece by four independently fastening piece monomer form, the section of fastening piece monomer is semicircle, one end is with adpting flange, the other end is the fastening end of section semicircular in shape, the inner side of described semicircle fastening end is processed with twice and connects locating slot, and adpting flange is processed with attachment hole.
The connecting means step of described composite pipe is:
1., first the connection locating slot inside each fastening piece monomer is coated glass fibre reinforced plastics clay, wherein every two fastening piece monomers up and down relatively, flange side alignd with body one end and to be fastened and fixed up and down by bolt and nut, the method that the body of opposite side is same connects, stand-by after being solidified into one.
2., by be cured 1. in two bodys relative, insert plug connector respectively, wherein bayonet end and internal diameter of tube body are closely connected, and the attachment hole one_to_one corresponding on attachment hole during grafting on plug connector spacer flanger and opposite opened fastening piece adpting flange is arranged.
3., on corresponding each attachment hole and attachment hole lay screw bolt and nut, fastening whole screw bolt and nut, makes plug connector all enter body endoporus, finally realizes the connection between two bodys simultaneously.
The present invention has following advantage and good effect:
1, Inner tubing layers of the present invention adopts polytetrafluoroethylmaterial material anti-corrosion capacity strong, and almost can resist all chemical mediators (comprising red fuming nitric acid (RFNA) and chloroazotic acid), it can work for a long time at 230-260 DEG C, and its wear resistance is given prominence to especially.The outer frp layer that adopts overcomes the good shortcoming of polytetrafluoroethylmaterial material internal layer insufficient strength, and the problem not only solving anticorrosion difficulty but also the problem solving cost high turn increase working life.
2, composite pipe of the present invention has simple and reasonable, and connecting means is simple and convenient, and favorable anti-corrosion effect, cost are low, intensity is high, the life-span is long, and using scope is wide, quality is light, be convenient to the advantages such as installation and transport.
