Abstract

The invention makes public a kind of compression joint tool for pipeline joint. The invention consists of compression joint hand grip and compression joint clipper. In the head of the clipper, two correspondent semicircular compression joint caps are fixed on the two semicircular clipper gates. Two raised bars are on the two side of the clipper gate, and wedge slots that are on ektexines of the gate of the compression joint cap. The compression joint cap can be change so the invention can be used for pipeline joint with different size, material or norm.

Description

technical field [0001] The invention relates to a pipeline joint crimping tool. Background technique [0002] Aluminum-plastic composite pipe is an ideal product to replace traditional galvanized iron pipe and plastic pipe. In 1998, it was designated by the Ministry of Construction as a key product for promotion and application, and was designated by the State Science and Technology Commission as a promotion project for the high-tech industry of Torch. Aluminum-plastic composite pipes and PEX pipes have become the leading products in the domestic water market. Most cities in China have banned traditional galvanized iron pipes for newly-built commercial buildings. The urban construction authorities in various places have formulated regulations for using aluminum-plastic composite pipes or PEX pipes to realize direct drinking water in newly-built commercial buildings. Strategic objectives. [0003] The advantages of aluminum-plastic composite pipe are: easy to bend, no reboun...
