Abstract
The utility model relates to a transport pipeline. The corrosion-resisting property of the inner wall of a common steel pipe is mainly improved. The structure is characterized in that a glass fiber reinforced plastic pipe is firmly and evenly adhered on the inner wall of the common steel pipe in a whole. The utility model has the advantages of corrosion prevention, low cost, and long service life. The transport pipeline can replace a stainless steel pipeline for transporting corrosive steam and liquid and can be applied to other pipelines by means of the advantages of low price and long service life. The service life of the pipeline can be prolonged.
Description
The utility model relates to a kind of conveyance conduit.Mainly be that corrosion resistance to the common steel tube inwall improves, make it can replace stainless steel pipeline to carry corrosivity vapour, liquid.
At present, being used to carry the pipeline of corrosivity vapour, liquid generally all is to adopt Stainless Steel Tube.But because cost is very high, application difficult.For reducing cost, some " lining pipes " have been developed in succession promptly: the certain thickness anticorrosive material of lining system one deck on the inwall of common steel tube.Replace Stainless Steel Tube with these lining pipes.As: glass lining pipeline, enamel lining pipeline, rubber lining pipeline or the like.Also useful high strength glass steel pipeline replaces stainless steel pipeline.Though, also all exist the some shortcomings part by the stainless steel pipeline cost cost of having compared all to a certain degree reduction.Easily burst as glass and enamel lining, be difficult for installing.The rubber lining life-span is short or the like.And these lining pipe manufacturer technologies are also all very complicated; Adopt the high strength glass steel pipe that certain deficiency is also arranged.As: because of the restriction of the releasing process of high strength glass steel pipe, the length of individual tubes is the longest also only to be 4 meters, causes pipe coupling too many thus, not only installs complicatedly, also easily forms evaporating, emitting, dripping or leaking of liquid or gas.
The purpose of this utility model provides that a kind of all price and performance are better than " the glass reinforced plastic lining pipeline " of other lining pipeline near stainless steel in intensity and rotproofness.
The purpose of this utility model reaches by following measures: a frp lining pipe is set, to improve rotproofness in common steel tube.
The drawing explanation of accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Do to describe in detail in conjunction with Fig. 1: " glass fiber reinforced plastics lining pipe " is mainly by common steel tube (1) with evenly be bonded as one glass reinforced plastic pipe (2) with the common steel tube inwall securely and form. (3) be connecting flange and copy the frp layer that becomes one with lining that pipeline docks with it. (4) be sealing gasket. Bolt (5) is fastening. (6) be the outer wall of steel pipe anticorrosive coat. (7) be elbow or other pipe fitting of lining.
The utility model is described further by accompanying drawing embodiment: the various lining pipes of prior art, manufacturing process generally all are to make bushing pipe earlier, then or adopt hot charging bonding; Or rotating centrifugal; Or high-temperature calcination etc.Complex process, the cost height.In addition steel pipe is also had certain requirement, and the length of every pipe only limits to also in 4 meters.Adopt above art methods, then can not make cheap practical glass fibre reinforced plastic liner tube.The utility model has then been created the technological method of one-step shaping lining, has finished simply, and cheap manufactures.
1, the reinforcing material of glass fibre reinforced plastics adopts the glass fibre zero twisted yarn, press after the caliber specification calculates consumption, is arranged in the tubulose introducing steel pipe with yarn boundling impregnation and with the glass bundle of impregnation and to the other end of steel pipe.
2, on the metal flange that common steel tube one end has welded, manufacture frp layer, and heat 70-90 ℃.
3, introduce subsequently to have heated to 70-90 ℃ corresponding die head in pipe and clamp-on into the pressurization attitude, die head moves to the other end of steel pipe with certain speed, promptly once finishes the forming process of the bonding and Glass Steel Tube of lined steel pipe inwall.
4, manufacture the frp layer of the other end flange by this method " 2 ".
Above manufacture process is finished by special device.
The utility model compared with prior art advantage is as follows:
1, cost is low: manufacture fiberglass because adopting glass fiber yarn, be down to 7 yuan/Kg so fiberglass part fee of material is minimum. Such as the fiberglass of 3 millimeters thickness of Dg108 common steel tube liner, only 10 yuan/meter of fee of materials. Adopt in addition once moulding method, the efficient height, expense is low, replaces stainless steel pipes with it, approximately only has to be equivalent to former cost about 30%, compares with other Lined Pipeline, approximately reduces cost 50%.
2, intensity height, life-span are long, and single tube length can reach 6～8 meters, are easy to install, and be practical.
3, the utility model can be widely used in other pipeline owing to have above-mentioned advantage, prolongs pipeline life, and from urban construction and construction, aspects such as consumptive material are that country saves appreciable fund.
Claims (1)
1, a kind of " glass reinforced plastic lining pipeline " is to be made of common steel tube (1) liner glass steel pipe (2) and the flange (3) that duplicates frp layer.It is characterized in that: the glass fibre reinforced plastics part firmly sticks to one equably with common steel tube, flange.
