Embodiment Construction

[0022] The method for measuring pipe compressive strength and blast resistance of the present invention comprises the steps:

[0023] a. Prepare the pipe sample and four top plates, measure the inner hole diameter D and length B of the pipe sample, and determine the outer arc surface radius of each top plate according to the inner hole radius of the pipe sample, so that the outer arc surface of each top plate The radius is the same as the radius of the inner hole of the pipe sample, so that the length of each top plate is greater than or equal to the length of the pipe sample, and the outer circular surfaces of all the top plates can be spliced ​​into a ring;

[0024] b. Splice all the top plates into a circle and place them in the inner hole of the pipe sample, so that the inner wall of the pipe sample is in contact with the outer arc surface of each top plate;

[0025] c. Simultaneously apply a force T to each top plate in the radial direction from the inside to the outside ...

Abstract

The invention relates to a method for measuring compressive strength and anti-explosion capability of tubing. The method comprises the following steps of: preparing a tubing sample and more than three top plates; measuring the diameter D and length B of the inner hole of the tubing sample; selecting and determining the radius of the outer arc surface of each top plate according to the radius of the inner hole of the tubing sample; making the radius of the outer arc surface of each top plate is identical to the radius of the inner hole of the tubing sample, and making the length of each top plate greater than or equal to the length of tubing sample, and splicing the outer circular surfaces of all the top plates into a ring. The equipment comprises a bracket, wherein the bracket is fixedly connected with the rear end of a guide sleeve barrel; a plunger can be glidingly arranged in the guide sleeve barrel; the rear end of the plunger is connected with a piston rod of an oil cylinder; the body of the oil cylinder is arranged and fixed on the bracket; the front end of the plunger is provided with a regular polygonal cone or a regular polygonal prismoid or a cone or a cylinder. The method and equipment have the advantages of compact structure, simple operation, high working efficiency and convenient use.

Description

technical field [0001] The invention relates to a method and device for general measurement of force or stress through mechanical operation, in particular to a method and equipment for measuring the compressive strength of pipes. Background technique [0002] The existing pipeline internal pressure test is to intercept a certain length of pipeline, seal both ends with plug fixtures, then fill the pipeline with liquid, and then use a pressure pump to pressurize to a specified pressure and maintain it for a certain period of time. In the first process, the pressure resistance capacity is determined by observing the condition of the pipeline; while the anti-burst pressure test is the same as the water pressure test in terms of the installation method of the pipeline plug, except that the pipeline is required to be pressed to damage within a certain period of time during the test. However, for some plastic pipes with large diameters used for water delivery, such as polymer compo...
