Underground HDPE (High-Density Polyethylene) Pipe

Overview:

Underground HDPE pipes are widely used for water supply, sewage, drainage, gas distribution, and cable protection. They are made from high-density polyethylene, a strong, flexible, and corrosion-resistant material ideal for underground installations.

Key Uses:

1. Water Supply Lines – For both potable and non-potable water.

2. Sewage & Drainage Systems – For carrying wastewater and stormwater.

3. Irrigation Pipelines – Used in agricultural fields for water distribution.

4. Cable Ducting – To protect electrical and telecommunication cables.

5. Gas Distribution – Safe for carrying natural gas and LPG.

6. Industrial Applications – For chemical transport and process lines.

Advantages:

• Corrosion & Chemical Resistant: Does not rust or react with soil chemicals.

• Leak-Free Joints: Fusion welding provides a 100% leak-proof system.

• Flexible & Strong: Can bend easily around obstacles, reducing joint count.

• Lightweight: Easy to handle and install, lowering labor costs.

• Long Service Life: Can last over 50 years underground.

• UV & Abrasion Resistant: Suitable for tough environmental conditions.

Features:

• Smooth inner surface for high flow efficiency.

• Available in coils and straight lengths.

• Resistant to impact and ground movement.

• Suitable for trenchless installation (HDD, pipe bursting, etc.).

Material of Construction (MOC):

• Base Material: High-Density Polyethylene (PE-63, PE-80, or PE-100 grades)

• Standard: IS 4984 / ISO 4427 / ASTM D3035

Working Pressure:

• Ranges from 2.5 kg/cm² to 16 kg/cm², depending on pipe class (PN) and diameter.

Working Temperature:

• Can withstand from -40°C to +60°C, suitable for most underground environments.

Jointing Methods:

1. Butt Fusion Welding

2. Electrofusion Welding

3. Compression Fittings

4. Flange Jointing

End Fittings:

• HDPE Flanges

• Tail Pieces

• Electrofusion Couplers

• Bends, Tees, Reducers, End Caps

SANDHYAFLEX PVC HANDRAIL
size:32mm Widthx4 to 5mm Thickness
40mm Widht x 4 to 5mm Thickness
50mm Widht x 4 to 5mm Thickness

• Railing handrail profiles are made of soft PVC, which is a thermoplastic, hence its features depend on the temperature (immersion in hot water facilitates the laying process).
• Alternating heating and cooling allows installation in tight arches of stair balustrades 
• Rail profiles give an attractive appearance to communication routes in residential buildings, office buildings or single-family houses.
• The use of PVC railing cladding not only improves functionality and safety, but also enlivens the interior and adds aesthetics.

 

Benefits

• aesthetic finish
• pleasant to the touch
• no maintenance required,
• handrail made of soft PVC

 

 Color Palette

We produce a handrail in various colors:

• beige
• brown
• gray
• black
• dark gray

 

Installation

• applied on heat (after heating, eg in hot water) for a flat bar, width 40 mm, thickness 5-8mm
• they are made of soft Pvc,
• rail bar should be mounted on a previously prepared flat bar, whose surface should be clean and smooth, without any unevenness that arise during welding
• the profile should be warmed up so that it is soft and flexible, the safest way is to bath the skirt in hot water, which will heat the profile
• the installation of the profile takes place in the following direction: from top to bottom,
• the profile can not be stretched over the length, because its excessive stretching at the moment of cooling will result in a return to its original shape
• installation in curves requires a stronger heating of the profile from the inside, which will facilitate its assembly
• due to the shrinkage of the material from which the product is made, it is recommended to leave a longer section of about 3-5cm until it is completely cooled and then cut to the correct length

When you’re looking for a 200 mm (≈ DN200) diameter HDPE pipe with a flange, here are the key considerations, followed by recommended product options and specs. If you want India-specific suppliers or pricing, I can dig deeper for you.

✅ What to check

1. Material & grade

   • HDPE pipe grades: PE 80, PE 100 are common. For example: a DN200 pipe of PE80 with collar flange is listed. 

   • Flanges / flange adapters: must suit HDPE’s thermal and mechanical characteristics (e.g., thickness, fusion etc.).

2. Standards & dimensions

   • Pipe standard: e.g., ISO 4427 for HDPE water supply pipes. (Landee)

3. End connection / flange details

   • Flange might be integral to the pipe (factory fitted) or via adapter/backing flange. For example: “HDPE Pipe with Flanges – flange connections at each end”. 

   • Ensure compatibility of bolt pattern, gasket etc. The flange must match the intended mating flange.

4. Application & service conditions

   • Are you using for potable water, sewage, industrial fluids? The environment affects material, corrosion resistance, temperature.

   • Temperature range: e.g., some HDPE pipes are rated from –40 °C to 40 °C. (Landee)

   • Installation concerns: handling, storage, jointing methods. (MyBMC)

5. Length / logistics / local availability

   • Many Indian suppliers list 6-12 m lengths for DN200 with flanges. 

   • Lead time, shipping, on-site jointing, cost of flanges/adapters.

🛒 Product options to explore

Here are some products you can review. Note: not all may exactly match “200 mm + flange” – you may need to ask the supplier for flange-end variant for DN200.

Highlights:

• 2 Meters Round 200 mm HDPE Sewage Pipe: This is 200 mm size, good starting point – check whether it has factory-fitted flanges or plain ends.

• 315 mm SDR11 PE100 HDPE Pipe: Larger diameter. Useful as a benchmark for large sizes with flange ends.

• The others are smaller sizes – useful if you’re considering options or scaling.

• You’ll want to ask supplier specifically: “HDPE pipe DN200 with flanged ends (either integrated flange or flange adapter)”, material grade (PE100/PE80), pressure rating (PN10/PN16 etc.), and confirm the flange standard (ANSI, IS, etc).
