Problems solved by technology

[0003] Although the peel strength reflects the stability of the bonding of the composite layers to a certain extent, the results of the peel strength test are average values, which only reflect the firmness of the bonding between the composite layers macroscopically.
The industry standard has other regulations on the stability of the composite layer, that is, CJT / 189-2007 has a separate requirement for the hydrostatic stability of the composite layer, and the test method is given in the industry standard, but if it is tested according to the industry standard The method needs to waste a lot of electric melting pipe fittings, and the cost is too high. At present, there are related fixtures on the market to replace electric melting pipe fittings, but there are two disadvantages. First, the sealing performance is unstable. Second, it cannot be better. Better to stress test the composite layer, the effect is not ideal
[0004] The pipe is damaged during use, always starting from the weakest point or an area, and then slowly expanding to the overall damage, finally causing the pipe to burst

Abstract

The invention discloses a test method and clamp for a steel mesh frame plastic composite tube. The method comprises the following steps of: preparing test clamps; and mounting the prepared test clamps at the two ends of a pressure test tube to be tested, wherein a fastening jaw of each test clamp is sleeved and clamped on the periphery of the pressure test tube end; a clamp pedestal is sleeved on the tube end of the pressure test tube through the fastening jaw, a rubber seal and a seal pressing plate; the rubber seal is arranged between the clamp pedestal and the pressure test tube; the seal pressing plate is arranged between the clamp pedestal and the fastening jaw; the rubber seal is squeezed among the clamp pedestal, the pressure test tube and the seal pressing plate; and the fastening jaw is fixedly connected with the clamp pedestal through a fastening bolt. Stripping strength and compressive strength of the pressure test tube are tested by taking water as a medium for the pressure test tube provided with the test clamp. The method is simple and convenient; the device has a simple structure and is easy to operate. The entire set of equipment is low in manufacturing cost and can be easily accepted by many enterprises.

Description

technical field [0001] The invention relates to a method and a fixture for testing the adhesive strength of an outer adhesive resin layer of a plastic composite pipe with a steel mesh skeleton. Background technique [0002] Steel mesh skeleton polyethylene composite pipe is a new type of high-tech and environmentally friendly chemical pipe that has emerged in China in the past ten years. It is a network structure formed by high-strength copper-plated steel wire winding and weaving left and right as the skeleton, high-density polyethylene as the base material (polyethylene is a special material for PE100 pipelines), and modified polyethylene---adhesive resin, It is a new generation of chemical building materials with pressure resistance, internal and external anti-corrosion formed by continuous and step-by-step extrusion compounding on the production line. The product specification is φ63~φ630mm, widely used in municipal water supply and drainage, petrochemical, electric pow...
