Description
Technical field
The utility model relates to a kind of heat-resistant glass steel tube.
Background technique
Glass fibre reinforced plastics is a kind of plastics that strengthen with glass fibre, and Glass Steel Tube promptly is the pipe that adopts glass fibre reinforced plastics to make.By twining or multi-lay winding is made, its mechanical property can be considerably beyond plastics by glass fibre and plastics for traditional Glass Steel Tube, even the tensile strength of the Glass Steel Tube that has will surpass carbon steel, and its intensity can be compared with high-grade alloy steel.Yet, because glass fibre and plastics all have very high thermal expansion coefficient, when the fluid temperature (F.T.) of being carried is higher, Glass Steel Tube meeting deliquescing on the one hand, its intensity can reduce, on the other hand, because of making pipeline impaired after the pipeline expansion.
For this reason, Chinese patent 1326064A number disclosed name is called " high-strength composite glass steel pipe " and provides a solution.It is sandwich layer that this kind composite pipe adopts steel pipe, is compounded with frp layer on inside and outside two faces of this steel pipe.Its meaning is to want to utilize steel pipe to dwindle expansion coefficient at high temperature, and can improve its intensity.But,, when the fluid temperature variations of being carried is big, both is separated, thereby cause pipeline integral body impaired because frp layer is different with the thermal expansion coefficient of steel pipe; In addition, the composite pipe of this kind structure connects and also has certain problem, if the structure that the end of steel pipe and inside and outside frp layer is adopted parts such as flange plate be connected simultaneously, the structure that perhaps adopts parts such as flange plate only pipe end to be connected or only frp layer connected, when carrying high temperature fluid, because frp layer extends axially the length that extends axially that length is greater than steel pipe after being heated, thereby frp layer and link damage in easily causing, so, even if the composite pipe of this kind structure is corrosion-resistant, also be not suitable for carrying high temperature fluid.
The name of Chinese patent 236781Y bulletin is called " compound glass steel pipe " and provides another kind of solution.This Glass Steel Tube adopts the fabric of overlapping winding as sandwich layer, is provided with the inside liner that is made of epoxy resin at the internal surface of sandwich layer, and outer surface is provided with the wire reinforced layer.Its meaning is to want to utilize inside liner to improve heat-resisting withstand voltage properties, utilizes the wire reinforced layer to improve intensity.As epoxy resin, the epoxy resin that epoxide number is higher, though intensity is also better during high temperature, its material is more crisp, cost improves relatively, and the low epoxy resin intensity when high temperature of epoxide number is relatively poor; Though and metal shielding axially can stretch arbitrarily, can solve steel and the fiber fabric layer expansion coefficient differs to problem, because wire is oxidized easily in the erosion that is subjected to wet gas or liquid, and then the working life that can reduce pipe.
In addition, Chinese patent 1614288A number disclosed name is called a kind of scheme that " connecting means of fiber reinforced plastic pipe " provides the connection Glass Steel Tube.That one end of this Glass Steel Tube is provided with taper and have internal thread accept head, the other end is provided with outside thread and can be screwed in a connection-peg of accepting in the head, and seal ring is installed accepting an inner end, and is excessive from joint area with the fluid that prevents to be transferred.But, when line transportation has the fluid of uniform temperature, the joint socket position that can directly act on by thermogenetic expansive force to be threaded, even and if the connection between the screw thread is very firm, also be difficult for bearing this active force, thereby cause pipeline to damage.
Summary of the invention
Task of the present utility model provide a kind of utilize when increasing the inside liner thermal distortion barrier performance and automatically the mode that expands of compensating axial solve the heat-resistant glass steel tube that causes problems such as reduction in working life because of thermal expansion.
Another task of the present utility model provides a kind of method that is used to make above-mentioned heat-resistant glass steel tube.
The tube wall of the heat-resistant glass steel tube that the utility model proposed comprises inside liner and mesosphere, inside liner is to be made of unsaturated polyester resin layer and the glass surface felt, glass fibre loop bonding felt, the chemical fibre grid cloth that are wrapped in this unsaturated polyester resin layer outer surface successively, described glass surface felt is double-deck, and also is compounded with thermal insulation layer at the mesosphere outer surface; The tube wall of one end of this Glass Steel Tube is provided with the socket of radial protrusion, and its other end is provided with the bellmouth that is used to accept the socket insertion of inwall radially outward expansion, and makes the axial length of the axial length of bellmouth greater than socket.The barrier performance of this Glass Steel Tube depends primarily on the ability of the thickness and the thermal deformation resistant of unsaturated polyester resin, if the thicker easy appearance be full of cracks of unsaturated polyester resin layer, so, when twining the glass surface felt, be under unsaturated polyester resin thickness state, to twine the glass surface felt, cause the unsaturated polyester resin layer extremely thin or can only form a smooth surface, its thickness is usually less than 0.15mm; Simultaneously, the glass surface felt is to cut glass yarn lay and the felt that forms with Bond bonding at random by the weak point of fixed length, because the glass yarn in the glass surface felt is thin more, its intensity is high more, so adopt double glazing surface felt can increase the intensity of Glass Steel Tube, can prevent effectively that again be full of cracks from appearring in the unsaturated polyester resin layer; Glass fibre loop bonding felt is by the certain thickness short glass fiber of irregularly placing in the plane that has, and constitutes by the direction of warp and weft loop bonding with the chemical fibre line together, and the thickness of this glass fibre loop bonding felt is generally at 380g/m
2, its major function one is the axial and radial strength that increases inside liner, the 2nd, play skeleton function, and destroy the structure of inside liner when preventing to twine the mesosphere; The chemical fibre grid cloth is the cloth that is made into the chemical fibre line, and its effect is to twine by reinforcing, penetrates glass surface felt and the unnecessary unsaturated polyester resin of glass fibre loop bonding felt and interior bubble thereof to extrude.
Described unsaturated polyester resin is to be made of the 199# unsaturated polyester resin.The glass surface felt is selected 30g/m for use
2The glass surface felt.Unsaturated polyester resin is a family macromolecule compound that is generated through condensation reaction by dibasic acid of unsaturated (or saturated) (or acid anhydrides) and dihydroxylic alcohols, and the 199# unsaturated polyester resin is meant a kind of trade mark in this family macromolecule compound.
Described thermal insulation layer is to be made of expandable plastic or polyethylene warming plate.Described expandable plastic is to be made of polyurethane foam material.
Unsaturated polyester resin layer in the heat-resistant glass steel tube that the utility model proposed is a base-material as adopting the 199# unsaturated polyester resin, its heat distortion temperature can reach 95-100 ℃, make this heat-resistant glass steel tube be very suitable for carrying high temperature fluid, long-term serviceability temperature is 90 ℃, can be used for making heating pipeline; Simultaneously, adopt layer glass surface felt can strengthen inside liner intensity and the be full of cracks of unsaturated polyester resin layer or the micro-crack extension that prevent in the inside liner, make this heat-resistant glass steel tube have extraordinary barrier performance.
