It can be divided into two kinds of natural pressure type and pressure-bearing type. The natural pressure type is usually made of single-sided rubber white canvas, no shape regulations, manufacturing technology is easier; while bearing pressure type must choose double frame raw materials, the appearance of more stringent regulations, so the production and manufacturing process is more complicated. At this stage, most manufacturers of pressure-bearing pipeline compensators are using the molded method of manufacturing with a split die core, and their semi-finished products are processed by hand to meet the rubber cylinder. Soft joint this processing process manual production stage, quality is not easy to obtain manipulation.
Clamp type is chosen to replace the flange and bolt, when applied, it is convenient to put the two sides of the clamp type soft joint each set of clothes on the official road to be connected, according to the stainless steel plate clamps to fix the soft joint with the pipe without moving the connection; when disassembled loosen the clamps can be. In order to achieve the purpose of compensating for the offset of the pipeline formed by heat and cold shrinkage and water circulation. It has the following advantages over general flexible joints: Clamp type flexible joints save flanges and bolts, which saves the project expenses. Clamp type flexible joints do not need reverse side at the branch pipe, simplifying the working efficiency. Soft joints simplify the installation and maintenance work, which enhances the work efficiency.
