Understanding Pe Fittings and Their Applications

Among the many materials used for manufacturing pipes and fittings, one of the newer materials is polyethylene, or PE, as it is commonly known. PE is a plastic material and as such has many advantageous properties such as higher strength, high temperature resistance, corrosion resistance, non-toxicity and resistance to rusting. While PE pipes have widespread applications, PE fittings, which are available in the form of pipe connector, mitering fittings, twisting fittings and more at leading PVC distributors and hardware suppliers, also have specific applications. These applications are as follows:

1.Electrofusion fittings made from PE are used in natural gas transmission and distribution. These fittings are extremely costly as they have the highest safety factor owing to the sensitive nature of the area of their application. Electrofusion PE fittings are joined through the heating method, which allows for making different types of joints such as pipe to pipe, knee and pipe, and pipe couplings, among others.

2.Screw type PE fittings are, as the name suggests, equipped with screw mechanism. They are largely used in agricultural sector, limited to the irrigation systems. They are ideal for fittings where low and small pressure are in operation. These fittings are easily installed without needing any additional skill, time, or effort and can also be replaced with equal ease.

3.Welded PE fittings are perhaps the most popular type of PE fittings because the method of manufacture and quality of these fittings enables the fitting of any type of PE pipes, including those with the smallest size and the largest. These fittings are connected by boot fusion method as well as by electrofusion, which gives flexibility to the entire process.

4.Injection fittings are a type of PE fitting which are connected through the use of a butt welding machine. The method of their construction makes them unsuitable for use in high pressure applications and as such, they are generally suitable for use in agricultural domain. However, these fittings have many advantages as compared to other types of PE fittings, which includes their fast production, diversity, cost effectiveness, light weight and ready availability.

5.Twisting PE fittings also find limited use due to their smaller sizes and lack of ability to withstand higher pressures. Their application is generally for projects which are short-term or temporary in nature.
