HDPE pipes & PLB ducts for the solar industry
From solar-pump column pipes to DC/AC cable protection ducts — Almax equips solar EPC contractors, MNRE agencies and PM-KUSUM implementers with UV-stable, BIS-certified polymer piping built for a 25+ year plant life.
Every solar project needs polymer pipes — for water & for wires.
India’s solar-energy sector — utility-scale PV parks, rooftop plants, floating solar and solar-pumped irrigation under PM-KUSUM — depends on infrastructure that can survive decades of outdoor exposure. Steel corrodes, PVC embrittles, RCC cracks. HDPE and PPR do not.
Almax Polymers supplies UV-stabilised HDPE water pipes, PLB (Permanently Lubricated) HDPE cable-protection ducts and HDPE DWC drainage pipes to solar EPC contractors, module manufacturers, state nodal agencies and MNRE-funded programs. Every pipe is BIS-licensed, tested in our in-house lab, and available for inspection by CIPET, RITES, SGS, PDIL and Crown Agents.
Whether you’re installing a 5 HP solar submersible pump for a farmer under Component B of PM-KUSUM, laying kilometres of DC combiner-box cabling across a 500 MW park, or draining a transformer yard through the monsoon — Almax has the pipe.
- Built for solar-farm sun exposureBlack HDPE with 2.5% well-dispersed carbon black — UV stable for 25+ years of direct sunlight.
- Non-corrosive, no scalingImmune to acidic soils, salt-laden coastal air and mineralised borewell water. No galvanising to fail.
- Fusion-welded leak-proof jointsButt / socket / electrofusion joints — stronger than the pipe itself. Zero leakage across cable-trench crossings.
- Long coils for fewer jointsUp to 200 m coils for smaller diameters — dramatically reduces joints across long inter-row cable runs.
- BIS-certified & PM-KUSUM compliantIS 4984:2016 water pipes and TEC-approved PLB ducts — matches PM-KUSUM, MNRE and SECI tender specs.
- Third-party inspection readyCIPET, RITES, SGS, PDIL and Crown Agents inspections accepted for large solar EPC packages.
Four proven use-cases in every solar plant
From the borewell riser under a farmer’s solar pump to the underground cable duct running between PV strings and inverters — Almax pipes serve where the sun meets the ground.
Column Pipes for Solar Submersible Pumps
Under PM-KUSUM Component B & C, thousands of solar-powered submersible pumps are installed for farm irrigation and drinking water. Almax HDPE riser / column pipes carry water from the borewell to the surface with zero corrosion, no scaling and a leak-proof fusion-welded connection at every joint — outperforming galvanised iron column pipes that rust and lose pump efficiency within 3–5 years.
- Sizes 32 mm to 200 mm OD
- PN 6 to PN 16 pressure ratings
- PE 80 / PE 100 grades
- IS 4984:2016 compliant
- Trouble-free 25+ year service in borewells
PLB Ducts for Solar Cable Protection (DC & AC)
Solar farms lay kilometres of DC cables from PV strings to combiner boxes and AC cables from inverters to transformers. Almax PLB (Permanently Lubricated) HDPE ducts protect these cables from mechanical damage, rodent attack, UV degradation and moisture ingress. The permanent silicone inner coating (COF < 0.1) enables cable-blowing over 2 km+ — critical for large ground-mount PV parks.
- Outer sizes 32 mm to 63 mm
- Silicone solid-lubricant inner layer
- UV-stabilised HDPE compound
- Ripcord for easy field slitting
- Colour coding available (DC / AC / earth)
HDPE Pipes for Solar Panel Cleaning Water Lines
Utility-scale PV parks lose 5–15% generation to dust and soiling. Cleaning networks — from raw water tanks to robotic or manual cleaning nozzles across panel rows — need long, buried, UV-resistant, potable-grade pipe. Almax HDPE water lines carry DM / raw water across sun-baked sites for decades without cracking or bio-fouling, unlike PVC pipes that embrittle in direct sun.
- Sizes 20 mm to 400 mm OD
- PN 6 to PN 25
- Black PE 100 with 2.5% carbon black
- UV stable in direct sunlight
- Fusion welded — zero leakage joints
HDPE DWC Pipes for Cable Trenches & Site Drainage
Solar-park cable trenches, transformer yard drainage and inverter-station stormwater lines all use HDPE double-wall corrugated (DWC) pipes. High ring stiffness (SN 4 / SN 8), lightweight sections and rubber-gasket joints make site installation fast, and the corrugated structure withstands heavy vehicular loads on internal service roads.
- Sizes 75 mm to 1000 mm ID
- SN 4 and SN 8 classes
- Smooth inner bore for flow
- Rubber gasket & socket joints
- Root-resistant, chemically inert

Common questions from solar EPC teams
Which Almax pipe is used as the column / riser pipe for solar submersible pumps?+
HDPE water pipes to IS 4984:2016 — typically 32 mm to 110 mm OD in PN 10 or PN 12.5 depending on borewell depth and pump discharge. HDPE column pipes are corrosion-free, lightweight (about 1/8th the weight of GI), and last the full life of the solar pump without rust or scaling.
Do you supply PLB ducts for DC solar-cable protection?+
Yes. Our PLB (Permanently Lubricated) HDPE ducts — 32/26, 40/33 and 50/42 mm — are widely used in ground-mount PV parks to protect DC string cables and AC LT cables between inverters and transformers. Cable-blowing distances beyond 2 km are achievable due to the low COF (< 0.1) inner layer.
Are your pipes suitable for PM-KUSUM solar pump projects?+
Yes. Our HDPE column pipes are BIS licensed and match the specifications used by MNRE, state nodal agencies and EESL under PM-KUSUM Component B (standalone solar pumps) and Component C (feeder-level solarisation). Third-party inspection by CIPET / RITES / SGS is supported.
Can HDPE pipes withstand direct sunlight on a solar farm?+
Yes. Almax HDPE pipes contain 2 to 2.5% well-dispersed carbon black which provides UV stabilisation for outdoor exposure. Field data on HDPE water lines shows 30+ years of service in direct sunlight without cracking or degradation.
What size DWC pipes do you supply for solar-park drainage and cable trenches?+
HDPE DWC (Double-Wall Corrugated) pipes from 75 mm to 1000 mm ID, in SN 4 and SN 8 ring-stiffness classes. Common solar-park usage is 200–400 mm SN 8 for internal road cross-drainage and 90–160 mm for concealed cable-duct crossings.
Do you deliver to remote solar-park locations in Rajasthan, Gujarat, Karnataka, Andhra & Tamil Nadu?+
Yes. We supply to solar parks across India via road and rail dispatch from our Sonipat (Haryana) manufacturing facility. LC-backed dispatch and staggered project deliveries are standard for large EPC packages.
