Grooved pipe fittings are a new type of steel pipe connection fittings, usually called clamp connections. They have multiple advantages. The installation speed of this type of product is very fast and reliable, economical and environmentally friendly, and will not be restricted by the site. So what are the requirements for the installation of this type of product? Let's follow the editor to learn about it together. I hope that through the introduction of this article, everyone will have a deep understanding of this type of product.
The installation requirements of grooved pipe fittings are specifically introduced as follows:
1. When ordering products, you need to choose a suitable sealing ring. Different media in the pipeline require sealing rings of different materials. There are currently eight different materials of sealing rings on the market to suit different media.
2. Pipeline grooves (also called rolling grooves) are the key process of pipeline connection and an important part of determining the quality of grooved fittings connection. The width and depth of the groove must meet the requirements.
3. When rolling grooves, the end of the pipe mouth should be flat and free of burrs, and the end should be perpendicular to the pipe axis, so that the rolled groove can be perpendicular to the central axis of the pipe. At the same time, the length from the groove to the pipe end should be equal. If the ovality of the pipe and the wall thickness of the welded galvanized pipe are uneven, they should be corrected as much as possible during the rolling grooves, otherwise the grooves will have uneven depths and their tightness cannot be guaranteed.
4. For the groove connection of seamless steel pipes, products that have been galvanized by regular manufacturers should be selected. If the method of purchasing seamless steel pipes and then galvanizing them outside is adopted, the quality of galvanizing cannot be guaranteed due to oxidation and rust caused by long-term storage of steel pipes. The adhesion of the galvanized layer is poor, and the galvanized layer is easy to crack or even fall off during the rolling grooves, thus affecting the sealing and service life.
5. The use of rigid joints and flexible joints in grooved fittings should be reasonable. Rigid joints are suitable for pipe ends that require rigid connection in low-pressure pipelines, such as sprinkler risers, long-distance straight pipelines, valves, equipment, etc., and are required to be used in situations where the pipeline is not allowed to have displacement, angles, and torsion to obtain good rigidity. Flexible joints are suitable for medium and low pressure pipeline connections. After installation, the pipeline is allowed to have appropriate contraction and deflection to compensate for the slight displacement of the pipeline. It is more suitable for pipeline installation in uneven environments. It can also absorb noise, vibration, and seismic stress. It is generally used in the inlet and outlet pipes of water pumps in fire protection systems.
6. If the fire horizontal pipe is long, when using a hanger, in order to suppress the pipe to prevent the pipe from collapsing, it is recommended to use a flexible joint in the middle part to ensure that the axial pipe is not too large, so as not to affect the bending of the horizontal branch connected to it.
