This kind of development speed has aroused people's strong curiosity, and its installation technology has gradually attracted attention. During the processing of grooved pipe fittings, the first thing is to have reliable support. General construction personnel will install directly on the bottom of the clamp as a platform to reduce the damage to the pipe fittings during the groove pressing process and avoid affecting the later use. The most basic of the groove pressing process is to install in accordance with the requirements of the instructions, so that the accuracy of the process can be guaranteed. In the selection of the grooving mold, it must be selected correctly. For example, the mold that has been used for a long time or is damaged should not be used, otherwise it will affect the quality of the grooving process. After pressing the groove, clean up the scum remaining on the spot in time, apply anti-corrosion paint at the pressure groove, handle it gently, and ensure the safety of the pipe fittings. At present, pipelines adopting grooved pipe joint connection methods are gradually promoted in various types of building installations, and their fast and reliable characteristics are being recognized by colleagues in the installation industry, and they are also widely used in the construction of fire protection projects. However, what problems should be paid attention to when connecting rigid clamps and flexible clamps with different connection methods have not been introduced in more detail in the existing design and construction specifications. The clamp industry has been published in the existing product standards of our country. Many provisions of the standard only involve manufacturing standards and related test content. In actual construction, the problems encountered when pipes are connected by clamps and their solutions are put forward. The installation of rigid clamps on DN≤250 pipelines is carried out according to the product manual provided by the manufacturer, and generally satisfactory results can be obtained.
