Without fittings, today it is impossible to equip a water supply system or a heating system, sewerage system. Given the variety of modern pipelines, manufacturers offer a huge variety of fittings, distinguished by shape and material of manufacture. Modern steel flanges malaysia is a sanitary element designed to connect into one system of pipelines and various equipment: heating boilers, boilers, mixers, plumbing fixtures, etc. Fittings help to make a turn, reversal of the pipeline, or its transition to a smaller (larger) diameter. When choosing connecting or transition elements, it is necessary, in addition to the diameter, to take into account the material of manufacture of the pipeline and equipment receiving pipes.
Steel and copper piping
To connect them, manufacturers offer threaded, welded or flanged fittings. When buying such hardware, you need to pay attention to the perpendicularity of the ends and their flatness. The quality of the joint seal depends on these parameters. The role of the sealant is played by tow or a special FUM tape. For better fixing of the seal, lock nuts made of steel, brass, bronze or cast iron are used.
Copper elements are well connected exclusively using fittings made of copper or brass. Connecting parts can be made split or capillary brazed. Copper fittings are widely used in heating and plumbing systems, as well as in the installation of air conditioners and refrigeration units.
These products are the most common in everyday life today. Through such fittings, you can completely mount the water supply, heating network inside the house, apartment. The connecting element for a metal-plastic pipe consists of an annular, a spacer gasket, a pair of nuts (sometimes 3-4), and a fitting. When purchasing a connecting piece for metal-plastic pipes, pay attention to the weight; a good fitting is noticeably heavier because it is made of brass or bronze.
Polypropylene and PVC pipelines
Fittings for connecting PP or PVC pipes are made of the same material. This allows you to connect the necessary parts by soldering using a special soldering iron with a heating element in the form of a ring. All installation work after a simple preparation can be done independently – some companies rent a soldering iron. Polypropylene fittings are inexpensive – manufacturers offer parts of all kinds of configurations; you can always choose an element of the required diameter, bend. Since plastic fittings are not faked due to their low cost, you can safely go to the store to buy.
Types by material of manufacture
Fittings are made from steel, cast iron, brass and polypropylene. Steel fasteners are versatile, as they are used to connect both metal and polypropylene pipes. Cast iron ones are ubiquitous in Soviet-built houses – they are mounted together with batteries made of the material of the same name. Brass and polypropylene fittings are characterized by increased heat resistance.
There is a wide variety of fittings on the market now, so you need to choose them very carefully. Each species has a specific purpose. If the battery is securely attached to the wall, then the fittings will last long enough.
Installation requires special skills and equipment, as well as coordination with the management company and neighbors.…
