What's the difference between a leak patch and a Haf joint
The main differences between a leak repair and a Haf joint lie in definition, use and construction.
Definition and use
Haff is a kind of pipeline leak stopper, mainly used for pipeline repair. It consists of two bodies and two rubber pads, easy to install, just the two bodies at the water leakage to tighten the nut to complete the rush repair of the pipeline. Huff section is suitable for various scenarios, including municipal water supply and drainage pipelines, industrial pipelines, etc. It can quickly seal pipeline leaks, save water shutdown time and reduce emergency repair costs .
leakmender Usually refers to a device for repairing pipes, also known as a clasp. It is composed of symmetrical two-part clasp, sealing ring and fastener, which is suitable for water leakage and leakage accidents caused by trachoma, porosity, transverse and longitudinal fracture of various liquid, gas and pressure pipelines. The leak filler has the advantages of simple structure, convenient use, saving labor, time and cost .
Structural characteristics
Haf joints are usually made of high-quality metal materials such as cast iron and ductile iron to ensure high strength and durability. The sealing part is equipped with rubber rings that are resistant to oil, water and aging, which can effectively fill the gap at the pipe interface and prevent media leakage. When installing, only need to cover the Haff joint in the leakage part, tighten the bolts, so that the upper and lower parts are closely fitted, so as to achieve an efficient sealing effect .
The leak repair device is composed of two symmetrical parts of the clasp, sealing ring and fastener, the clasp cavity, the outside is V-shaped, the upper and lower clasp joints are sealed by sealing strips, and are fastened by bolts and nuts. The utility model has the advantages of simple structure and convenient use, and is suitable for trachoma, porosity and fracture of various pipelines .
