Abstract
A high-strength composite glass-steel pipe for delivering corrosive medium is composed of central steel pipe, external glass fibre reinforced plastic layer made up by winding glass fibres around the steel pipe in same direction, and internal glass fibre reinforced plastic layer formed by centrifugal method with chopping fibres. It features high strength and antiexplosion and antileakage performance.
Description
The present invention relates to a kind of high strength glass steel tubing applicable to various bores, the middle and high pressure that is particularly useful for aggressive medium is carried tubing.
Advantages such as fiber reinforced plastic pipe has light-high-strength, corrosion protection, non-scaling, the mill resistance is little, conveying capacity big, long service life, engineering comprehensive cost are low are the indispensable functional materials of industry such as municipal water conservancy, petrochemical industry, mine metallurgy.Existing Glass Steel Tube says it all is pure Glass Steel Tube on material structure, main Wrapping formed technology or the centrifugal forming technology of adopting on method.Wrapping formed Glass Steel Tube adopts continuous fiber to strengthen, has higher mechanical strength, but because its intensity layer does not have sealing, the sealing of pipe relies on inside liner to realize, and inside liner has the characteristics of low stress cracking, make Wrapping formed Glass Steel Tube the seepage phenomenon often occur, academicly be called as ' inefficacy ', failure pressure is low to be the major defect of Wrapping formed Glass Steel Tube.The Glass Steel Tube of centrifuge method moulding, at action of centrifugal force subglass steel pipe walls compact structure, has good anti-leakage characteristic, but cut because the glass fibre that it adopts is short, thereby weakened the mechanical strength of pipe, caused the Glass Steel Tube of centrifuge method moulding often to produce the booster phenomenon in practice.Relatively poor by construction and installation technical quality and controlling level thereof in the pipework of China, above-mentioned phenomenon is more outstanding.
The high-strength composite glass steel pipe that the purpose of this invention is to provide a kind of antiseepage, the support of explosion-proof steel.
The object of the present invention is achieved like this, and tube wall is made of frp layer and steel pipe, and the inside and outside layer of steel pipe is respectively interior frp layer and outer frp layer.Adopt the directed winding shaping process of continuous glass fibre to be processed into outer frp layer, adopt chopped strand centrifuge method moulding process to be processed into interior frp layer.
Advantage of the present invention is: the anticorrosion tubing of a kind of novel high-strength that adopts resin base fibrous composite Glass Steel Tube and steel pipe to strengthen mutually, it had both overcome steel pipe Heavy Weight, installation difficulty, the big and corrosion-prone shortcoming of internal resistance coefficient, had overcome again in the lower and practice of simple glass steel pipeline reliability serious unsafe factors such as booster, seepage take place easily.Adopt rational moulding process, fundamentally guarantee the safe operation of fiber reinforced plastic pipe engineering.
Below in conjunction with drawings and Examples invention is elaborated.
Figure is a cross section structure schematic representation of the present invention.
This high-strength composite glass steel pipe with the stock of glass fibre reinforced plastics as the inside and outside layer of pipeline, sandwiches a surface treated steel pipe 2 at interior frp layer 1 and outer frp layer 3 centres as shown in the figure.The outer frp layer of steel pipe adopts winding shaping process, and strengthens so that continuous glass fibre is directed, brings into play the humidification of fiber to greatest extent; Frp layer adopts the centrifuge method moulding in the steel pipe, and changes material category and structure thereof according to different purposes, gives full play to its characteristics anticorrosion, wear-resistant, that the mill resistance is little; The use of steel pipe can improve the integral rigidity and the axial strength of pipe, reduce circumferential deformation, fundamentally prevent the phenomenon of inner layer glass steel generation low stress cracking, guarantee the reliability of pipe intensity, thereby satisfy the conveying requirement of different medium under different condition.
