HDPE gas pipe fittings are popularized with the wide application of HDPE gas pipes. The Middle East has the most abundant and high-quality oil resources in the world. There are many oil-producing countries such as Saudi Arabia, Kuwait, and Iraq. HDPE gas pipes are used in the field of gas transportation. It completely solves the corrosion of steel pipes and cast iron pipes and the leakage of joints, thereby ensuring the safe operation of the gas pipeline network system.
Advantages of HDPE gas pipe
The HDPE gas pipe is made of inert PE material, which can resist the erosion of various chemical media. The friction coefficient of the pipe wall is low, the flow resistance is small, and the conveying capacity is strong. The elongation rate generally exceeds 500%. PE gas pipe has good shock resistance, slow crack growth (SCG), rapid crack growth (RCP) ability, flexibility and scratch resistance. HDPE gas pipe has very strong adaptability to the uneven settlement of the pipe foundation and strong wear resistance. It can adopt a variety of non-excavation methods, which greatly facilitates the construction and installation of work. The system cost is low, and the maintenance cost can be greatly reduced. engineering cost. It is because of the many excellent properties of HDPE gas pipes that it was quickly promoted and used in the Middle East market, which led to the popularity of gas pipe fittings.
Specifications and models of HDPE gas pipe fittings
In terms of types, there are straight-through, different-diameter straight-through, positive tee, variable-diameter tee, 90° elbow, threaded joint, plug, etc.
In terms of size, there are basically Φ20, Φ25, Φ32, Φ40, Φ50, Φ63 specifications
HAILI PIPE can produce HDPE gas pipe fittings of various specifications and models according to customer needs to meet the needs of Middle East customers for various applications of pipe fittings. If the quantity is large, corresponding special specifications can be customized according to needs.
HDPE gas pipe fittings connection points
A key factor for PE gas pipeline laying experts to achieve long-term service life is the quality of laying. The annual gas transmission volume in the Middle East is also huge, so the safety of pipeline laying is extremely important. The HDPE pipe fittings have a variety of unique properties to make the laying of the pipeline safer and faster. At the same time, correct construction design and installation procedures will enable these superior properties of the pipeline to be brought into play to a greater extent.
Hot-melt installation of pipes and fittings Buried polyethylene PE pipes and fittings for gas use hot-melt socket connection below D90 mm, and hot-melt butt joint for pipe fittings above D90 mm. In order to correctly install the pipeline system and ensure the safety of users and project quality, we It is recommended that customers in the Middle East use the multi-angle welding machine and hot-melt butt joint machine provided by our company.
The welding steps are as follows:
1. Fix the pipes and pipe fittings to be welded on the butt joint machine, use fixtures according to the size of the pipes, and plan the end faces with milling cutters to make the butt end faces smooth, clean and vertical.
2. Adjust the height of the pipes and fittings so that the end faces of the pipes and fittings to be welded are completely matched, and connect the heating plate.
3. After the heating plate is automatically heated to the rated temperature, the pipes and fittings to be welded are combined to heat the end faces. After the heating time is reached, the pipes and fittings are separated from the heating plate, and then the two heating end faces are merged and docked to form a joint. Uniform flange, leave to cool. The technical requirements for hot-melt butt joints are met.
HAILI PIPE is a professional manufacturer of HDPE pipes and pipe fittings.
