Applicants of HDPE pipes & fittings
HDPE pipes & fittings are most suitable for agriculture (column pipes for submersible pumps, suction and delivery of water, sprinkler systems, drip/lift irrigation systems etc.), portable water supply, Industrial (Chemicals, corrosive effluents, under water pipes, sewerage handling, radio active waste etc.) and utilities (underground cable ducting) purpose.
HDPE pipes & fittings are a safe, long lasting and cost effective solution for various application like portable water supply, water distribution, irrigation, drainage, sewerage, industrial applicants like coal slurry, coal ash, sand, chemicals, hazardous fluid waste bore-well application and infrastructure projects.
Butt-fusion procedure For HDPE pipes & Fittings
Butt Fusion is the most important and widely used method of connection for HDPE pipes larger than 110 mm. It is a method of jointing pipe ends by way of heating and cooling under pressure, resulting in pipe joints as strong as the pipe itself.
The principle of butt fusion is to heat the pipe ends to a designated temperature (200-220 C) under pressure for a specified amount of time, then the pipe ends are fused together under pressure for a period of time.
A preparation before welding is necessary. Get ready of the pipes & fittings, and correct butt welding machine as per pipe dimension. Insert two pipes ends on both side of the machine clamps, adjust the alignment of pipe line by tightening or losing bronze nuts on the top aluminum clamps, and clean outside and inside pipe surface.
The major procedure of butt welding including 4 steps:
a). milling process
Insert the facing tool or trimmer between the two pipe ends into the lock position on the welding machine，Start the facing tool or trimmer by turning on the control switch. Slowly approach the pipe ends towards the facing tool or trimmer by controlling the directional valve on hydraulic control unit while keeping control pressure a little higher. The cutter will cut the surface of both pipe ends making them clean, plane and parallel.
b). Effect after milling
Remove the facing tool or trimmer from welding machine to the support frame and clear the facing scraps
from pipe ends. Inspect the ends, they must be clean and plane; otherwise repeat the step 3 – 5 again. During the clearing and inspection, avoid any contact with the surface of pipe ends
c). Heating Process
Check the heating plate temperature on the setting range; cleaning both heating plate side with cleaning agent and insert its back to support while waiting for welding operation to start.
To start with the welding process, begin with the alignment stage by inserting the heating plate between the two pipe ends, moving both pipe ends close together until contact with the heating plate. Start the build up pressure to the alignment pressure level (P1 + drag pressure), maintain the pressure until there are welding seam appear. In this stage, the uniform bead should had been created between the heating plate throughout the whole circumference of both pipe ends. Continue to the heating-up stage by reducing pressure and maintaining the heating-up pressure level (P2) along heating-up time (T2)
d). Cooling Process
Open both pipe ends, carefully remove the heating plate without touching the melted area and see to it that the removing time should not be longer than the changeover time (T3), insert heating plate to the support. Immediately increase pressure up to the joining pressure level (P3 + drag pressure) within the joining pressure built-up time (T4). Uniform beads must be created throughout the whole circumference of the pipe joints. Maintain or Keep the joining pressure constant throughout the cooling time (T5) or until the welding joint cools down. Avoid forced cooling down by applying water.
* What’s the difference between HDPE elbows & HDPE bends?
A: They are referring to the same products.
* How many types of HDPE elbows can SUNPLAST provide?
A: SUNPLAST can provide three types of elbows, which are: HDPE 90 degree elbow, HDPE 45 degree elbow & HDPE 22.5 degree elbow. All HDPE elbow fittings are injection molded type, and be made by virgin PE100 material.
* Can HDPE fittings connect to PVC pipe? Or can HDPE fittings connect to PPR pipe?
A: For thermal plastic fittings, they can be connect to the pipes with same material grade only. So, for HDPE fittings, they can be connected to HDPE pipe only, but can’t connect to PVC pipe or PPR pipe.
* How can we connect HDPE pipes to PVC pipes?
A: Since HDPE pipe & PVC pipe are made of different material grade, they are unable to connect together by “heat-fusion”.
The possible way to connect them together is by flanged connection. To use HDPE flange adaptor & HDPE backup flanges to make it possible to connect to PVC flanges.
* What’s the warranty can SUNPLAST provide?
A: All our HDPE fittings are made of virgin PE100 material, and are designed for 50 years lifetime. SUNPLAST will provide a warranty time in quality of 10 years for regular use.
* What’s the packing method for the fittings?
A: For small diameter poly fittings dn50~250mm, our packing method is carton. The big diameter fittings dn280~dn800mm, they will be wrapped by PP bags. Big diameter fittings can also be packed by pallets or wooden cases.
SUNPLAST can do the packing as per customers request.
