The FLOLINE 3-W pipe, manufactured from premium engineering-grade HDPE material, is ideal for road culverts across roads and highways. They are widely used as road crossings in plantations, as well as alternative to concrete culverts on rural and urban roads.

In soft ground conditions, they can be designed to be used without piling foundation, unlike concrete culvert systems. In such application, FLOLINE 3-W provides a very cost effective road construction solution.

FLOLINE 3-W culverts can also be used to rehabilitate and slipline damaged concrete culverts without the need to excavate and divert traffic.

Product Features

> SIRIM CERTIFIED & SPAN APPROVED – FLOLINE 3-W pipes are certified to DIN 16961 Part 1 & 2 by SIRIM with Product Certification Listing by SPAN (Suruhanjaya Perkhidmatan Air Negara)

> EXCEPTIONALLY STRONG & TOUGH – Due to its profile wall design, FLOLINE 3-W pipes has exceptionally high strength in ring and bending stiffness with excellent long term load bearing capabilities. Able to withstand 40-tonne vehicle loads and burial depths of 20m depending on soil backfill conditions

> FLEXIBLE – Able to bend and conform to soil conditions without fracture failure

> CORROSION RESISTANT – HDPE requires no protective painting maintenance against rusting

> UV RESISTANT – the HDPE material for FLOLINE 3-W pipes contains carbon black additives which are excellent UV retardants for outdoor exposure

> LIGHTWEIGHT – HDPE products are inherently light and eases transportation, handling and installation

> CHEMICAL RESISTANT – HDPE, being an inert material, can resist the extremes of pH in soil, sewage and wastewater without degrading

> ABRASION RESISTANT – HDPE resists abrasion better than conventional material like concrete and steel which can pit and rust. As a result, FLOLINE 3-W pipes can ensure good, long-term flow characteristics

> REDUCED RISK OF LEAKAGE – FLOLINE 3-W pipes are available in long lengths and requires fewer joints
