Production technology of wear-resistant composite pipe filled with adhesive cement

Abstract

The invention relates to a production technology of a wear-resistant composite pipe filled with adhesive cement. The technology comprises the following steps that a pipe is horizontally fed, horizontal filling of the adhesive cement is performed, an outer sleeve steel pipe is horizontally fixed to a support, one end of the outer sleeve steel pipe is tightly connected with a grouting sealing hoop, a plurality of fixing blocks are arranged on the outer walls of wear-resistant pipes, every two adjacent wear-resistant pipes are sealed and bonded, a pressure propelling device sequentially pushes all the wear-resistant pipes into the outer sleeve steel pipe through a propelling rod, a grouting cavity is formed among the outer sleeve steel pipe and the wear-resistant pipes through supporting of the fixing blocks, the grouting cavity is filled with the adhesive cement through a pressure grouting device, the outer sleeve steel pipe and the wear-resistant pipes form the wear-resistant composite pipe, the grouted wear-resistant composite pipe is maintained, the end, without the adhesive cement, of the wear-resistant composite pipe is repaired and is flush, and the outer surface of the wear-resistant composite pipe is treated. According to the technology, horizontal pipe feeding and horizontal adhesive cement filling are adopted, additional steps are reduced, the production period is shortened, the production efficiency can be improved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of wear-resistant composite pipe production, more specifically, it relates to a production process of wear-resistant composite pipe filled with bonding glue. Background technique [0002] In modern industrial production systems, the safe and reliable operation of the piping system connecting various equipment or systems is an important part of ensuring the safe operation of equipment or systems. Wear-resistant composite pipes are widely used due to their superior performance. The wear-resistant composite pipe includes the outer steel pipe and the wear-resistant material in the inner layer, so it is necessary to use adhesive glue to tightly combine the steel pipe and the wear-resistant material. The current wear-resistant composite pipe adopts horizontal type and vertical type of adhesive The method of slurry is to push the wear-resistant material into the steel pipe horizontally, then lift the semi-finished ...

Problems solved by technology

However, this process has obvious defects. In the process of hoisting and moving semi-finished products, the wear-resistant material of the inner lining is easy to shift or even fall off, causing injury. Moreover, because the filling process is divided into two stages, it is time-consuming, laborious and inefficient. The production cycle of wear-resistant composite pipe is long, and the quality cannot continuously reach the same standard, and there are uncertain quality hidden dangers. Therefore, it is necessary to propose a new wear-resistant composite pipe production process to solve the above problems
