The HDPE pipe welding is basically of two types: 1 Butt Welding Butt Fusion Welding involves simultaneous heating of both the pipes’ ends to be joined, to a specific temperature until a melting state is reached. Then the two ends are brought together in parallel Puhui Pipe manufacturer in China

Poly HDPE pipe lengths vary according to size, however, generally sizes up to 110mm are available in 6 metre straight lengths or 50m, 100m or 150m pipe coils. Sizes 125mm and above are generally available in 12 metre lengths, which offers huge cost savings by reducing nuers of onsite joins.
JUNNUO HDPE fabried pipe and fitting is means to solve installation situations where common fitting fail, meet more complex and cost efficient pipeline designs. 1. Size: DN20mm- 1600mm
Vinidex engineers can provide guidance in these parameters. The final weld beads should be fully rolled over, free from pitting and voids, correctly sized, and free from discolouration. When correctly performed, the minimum long-term strength of the butt fusion joint should be 90% of the strength of the parent PE pipe.
adapting welding parameters to suit a particular site situation: • The temperature around the heater plate where it touches the pipe is important. If it is too low then insufficient heat will be taken up by the pipe, if it is too high then potential degradation of the

Welding HDPE, or high-density polyethylene, is a normal procedure for joining lengths of pipe together, whether it be for industrial or home use. One of the benefits of welding HDPE plastics in smaller appliions such as you might find in home pluing systems is that no weld filler rod is necessary.
23/3/2021· Abstract. The standard method of joining plastic pipe in the field is the butt fusion process. As in any pipeline appliion, joint quality greatly affects overall operational safety of the system. Currently no simple, reliable, cost-effective method exists for assessing the quality of fusion joints in the field.
• The w elding team to prepare the welding parameter by calculating using the recommended values according to Table 1, Table 3 or machine data for the welding operation control. • Check the heating plate temperature on the setting range according to step 1; cleaning both heating plate side with cleaning agent and insert its back to support while waiting for welding operation to start.
The typical temperature range when welding high-density polyethylene HDPE is 220 to 400 C 428 to 752 F; the travel speed is typically 0.7 to 4 metres per second 2.3 to 13.1 ft/s. [5] Parameters [ edit ]

When fused according to the pipe and/or fitting manufacturers procedures, the joint area becomes as strong as, or strongAer than, the pipe itself in both tensile and pressure properties. As soon as the joint cools to near aient temperature, it is ready for handling.
2. Face the pipe ends to establish clean, parallel surfaces, perpendicular to the center line 3. Align the pipe ends 4. Melt the pipe interfaces 5. Join the two pipe ends together by applying the proper fusion force 6. Hold under pressure until the joint is cool 327-357
1/12/· HDPE pipe joining, plastic pipes and fittings produced from HDPE – PP – PVDF material is joined by butt welding, electrofusion welding or extrusion welding. Joining parameters differ according to DVS 2207-1, DVS2207-11, ISO 21307 PE100

HDPE pipe is extremely durable, and relatively expensive compared to other pipe, such as PVC. HDPE pipe is generally used underground and with a high rate of flow of whatever is being transported. It would not typically be used in a small scale system, like a home or a school or other general building.

HDPE fittings are widgets that reinforce both water and gas pipelines. While sizes can vary quite a bit, any fittings with a threaded portion greater than 32mm should ideally be reinforced externally. Placing a stainless HDPE ring around such a fitting, for example, will allow for maximum durability.
The details of the welding profile, that is, a plot of pressure versus time during the butt fusion welding of HDPE pipes, are shown in Figure 1. During butt fusion welding, the sum of the heater plate removal time and the time to achieve fusion joining pressure was varied from 10 to PE100
Tap welding guideline_english 1. 2009 THAI-ASIA P.E. PIPE CO., LTD. BUTT-FUSION WELDING GUIDELINE Butt-fusion technology is classified as a heat pressure related process by which the pipe end material of two different pipes are melted together Puhui Pipe manufacturer in China
Step 1: General Information on HDPE Pipe Welding. High Density Polyethylene, or HDPE, pipe is a heavy-duty style piping used in physically demanding environments to transport things from water to natural gas on landfills. HDPE pipe is extremely durable, and relatively expensive compared to other pipe, such as PVC.
Production of the heavy wall PE 100 pipe in OD 1200 mm SDR 11: AGRU has achieved to supply extruded pipes with a wall thickness of 109 mm in a pipe length of 11,8 m to reduce welds at site. In total 25 lengths were supplied and 24 pieces had been installed, as 1 pipe piece was kept as a spare for contingency purposes.
