Butt Fusion Fittings

Butt fusion fittings or hot melt pipe fittings are HDPE pipe fittings that adopting imported high-quality PE100 materials that have high resistance and long service life. They are regarded as ideal materials for the gas industry. They can also be used to convey fluid as well. Songjiang Smart Joint Company offers a wide range of butt fusion fittings for customers, such as butt fusion elbows, butt fusion tees, butt fusion reducers, butt fusion plugs and butt fusion flange stub.

Hot melt pipe fitting is extensively used in petroleum, chemical, pharmaceutical, electric power, shipbuilding, construction, paper making, aerospace, military industry, fire protection, metallurgy, gas, nuclear power, urban construction, food, water and environmental protection industries.

Advantages of Butt Fusion Fittings
1. Hot melt pipe fitting is well suited for connecting different specifications of SDR series pipes using the same material.
2. It is also applicable to connect pipes adopting material in same grade but different grades.
3. Our butt fusion fittings possess reliable connection performance, high interface strength, good airtight performance and stable welding performance.
4. Hot melt pipe fitting is not easy to be affected by environmental temperature variation and human factors.
5. Welding process is simple, thus this type of HDPE pipe fitting is easy to operate and convenient to use.
6. Embedded hidden spiral heating wire can effectively resist oxidation and corrosion, guaranteeing the stability of welding performance.
7. Smart Joint butt fusion fittings are of low production cost and maintenance cost.
8. Hot melt pipe fitting can withstand harsh chemicals without corrosion and leak. They offer leak-free connections which outperform other competing materials. Large fabricated pipe fittings can be special ordered.

1. Butt fusion fittings only use carbon and hydrogen elements as the material molecules. There is no toxic element. Our hot melt pipe fittings are reliable and healthy. They are not only used for hot and cold water pipes, but also used in pure water system.
2. It also has heat preservation and energy saving function. The thermal conductivity is 0.21w/mk, about 1/200 of that of the steel pipe. The vicat softening point of butt fusion fitting is 131.5℃. The highest working temperature is 95℃. Hot melt pipe fittings can meet the use requirements in the specification for hot water system in building water supply and drainage. Under the working temperature of 70℃ and pressure (P.N) of 1.0 MPa conditions, the service life of butt fusion fitting can reach more than 50 years (The pipes must be S3.2 S2.5 series or better series). Under room temperature (20℃), its service life can reach more than 100 years.
3. Hot melt pipe fitting has good welding performance. It is convenient for installation. The strength of connection parts is bigger than the strength of the pipe itself.

Installation Attentions
1. Installation personnel should be familiar with the general performance of butt fusion fitting connection and master the basic operation procedures.
2. They should be familiar with design drawing and know the building structure arrangement.
3. Before construction, check the material and accessories. It is forbidden to make hot melt pipe fittings exposed in the sun for a long time.
4. We need to set casings where the pipeline goes through wall or board. The inside diameter of casing should be 20 mm more than that of the pipe that goes through. Flexible non-combustible material is filled in the casing.
5. If butt fusion fitting is buried underground or in the wall or board, we must do hydrostatic test. When they pass the test, they can be buried.
