Because it facilitates multiple disassembly of pipeline elements, a detachable threaded connection on fittings is always better for performing maintenance or repairs. Pipeline sections that are soldered or welded together, as well as press fittings, provide a monolithic structure that improves operating reliability. Compression fittings should not be used in a heating system. How to choose fittings for metal-plastic, polypropylene, plastic, and copper pipes is a frequently asked question by purchasers. Consider the thickness of the pipe walls to the thickness of the fittings when making your selection. Fittings and pipes should be the same size. Consider the normal size of steel flanges in Malaysia while making your selection.
Pipes and fittings are installed.
We’ll make a few minor suggestions for installing polymer and metal-plastic pipelines. It is required to prepare the pipes before beginning the pipeline installation. Pipes are offered in separate lengths or wrapped into a coil, depending on the material of construction. We recommend pre-measuring the required installation lengths on-site. Measurements are taken between the planned connection nodes, according to the piping architecture. The workpieces should be cut after the measurements have been taken.
The sliced pieces are perfectly aligned throughout their length. The mounting joints must then be prepared. The pipes are cut with specialised instruments for this, following which the ends are cleaned and the chamfer removed. The allowed bending radius is taken into account while bending pipes. When installing fittings, make sure the device is not skewed in relation to the pipeline. Soldering or welding fittings involves a certain set of tools and equipment, as well as the requisite abilities.
Selection suggestions in general
Following these guidelines, you can select fittings for metal, polypropylene, and other types of pipelines: Make sure to consider the thickness of the pipe walls in relation to the fittings; while selecting press fittings, consider their standard size; select devices manufactured of the same material. Seek the guidance of a seasoned professional.
Fittings are made from a variety of materials. Steel, brass, and polypropylene fittings are the most commonly used. Anti-corrosion protection must be applied to metal fittings. Metal threaded or crimp fittings are used to join metal pipes for heating. Threaded, compression, capillary, self-locking, and press fittings are the various types of fittings used to install copper heating pipes. Solder fittings are used to join polypropylene pipes for water supply or sewerage. The use of integrated fittings guarantees that a portion of propylene pipeline is securely connected to a metal pipeline. Polyethylene pipes are fitted using either compression fittings or welding with polyethylene fittings.
