Polyethylene fittings in the polyethylene pipeline are of great importance and are of great variety, each of which is suitable for specific use and size. All polyethylene fittings are manufactured according to the DIN 16963 standard. The DIN 1693 standard has 15 parts. Injectable fittings are one of the most pervasive types of polyethylene pipe fittings. There is a lot of talk about the best type of fittings and a lot of confirmation can be written, but it is suggested not to use injectable fittings for sensitive and high -pressure lines, as well as for irrigation projects, sizes below 90 Use millimeters of this type of connections. Polyethylene injectable fittings are used as connectors of Carogite double -walled pipes (knee, divisive types) and do not have any problems because of the internal pressure on them, but in fire and fluid transfer systems at pressure and transmission systems. High temperature is not recommended to use injectable connections and use custom and customized fittings.
Injectable fittings have many major drawbacks due to their nature and production process that make these connections as multi -grade and inferior fittings, and the main disadvantage is the raw material of injectable fittings. (Recall that the best polyethylene pipeline is a pipeline whose pipe and fittings are integrated from one material and the fittings are produced and manufactured from the same pipe.) The most important point of not homogeneous and different polyethylene materials And the materials are pipelines that may be heterogeneous and the molecular texture and soot distribution and other factors vary. The second grade is the raw material of the production of injectable fittings used to produce injectable molding materials, but in the production of polyethylene pipes, Pipe Grade Extrusion materials are used. The third point in the process of producing injectable fittings is based on mold and pressure that may not be properly discharged and the air will remain in the mold and in the tissue of the connection, which is very observed and may cause difficulty when operating the line. Slow. Finally, it is lighter than other connections because of the use of inferior materials.
Injectable fittings are very comprehensive and are easily accessible in opposite sizes, very high variety, cheap, very fast production, lighter than other types of polyethylene joints and is therefore easier to install and execute.

Market construction is a database and network manufacturers and suppliers of construction products that introduce companies and specialize in building products. The overall goal of building the market is to communicate directly with the manufacturer. Dear buyers, they can refer to the market construction system for information on the price of polyethylene injection connections and buy from reputable sellers to buy polyethylene injectable fittings.
Manufacturers and suppliers can be on the market construction system Register And by putting construction products and inserting the bid price, inSpecial Sales Festival Participate and increase sales of their products.
