Weholite Structured Wall HDPE Pipe

weholite-large-diameter-pipe

Marley Pipe Systems is the South African licensee of the Weholite pipework system, a large diameter gravity or low pressure high density polyethylene (HDPE) pipe. Constructed by a unique patented structured wall process, Weholite can be manufactured in a range of ring stiffnesses and large pipe sizes from 280mm up to 3500mm – depending on customer requirements.

New production techniques have been combined with the latest raw materials technology to produce a durable pipe system with superior load-bearing properties, making Weholite the preferred solution for many municipal and industrial applications in both the public and private sector – including stormwater management, sewage treatment systems, culverts, marine pipelines and irrigation water distribution.

Weholite Structured Wall HDPE pipe provides all the technical advantages of equivalent polyethylene Solid-Wall pipes, but with substantial savings in weight, thus combining greater ease of installation with increased cost effectiveness when compared to traditional materials.

Weholite pipes are highly abrasion resistant, tolerant of ground movement and will not corrode or deteriorate in contact with a wide range of substances. These pipes are also characterised by its natural ability to "flex", which enables them to adjust to different loading conditions, vibrations, stress and soil movements without causing damage to the pipe.

Marley manufactures Weholite pipe under licence from Uponor Infra (formerly KWH Pipe) and are manufactured in accordance with Uponor Infra and Marley internal standards which are in accordance with EN 13476 and SANS 21138 and form part of an SABS ISO 9001:2008 quality management system. Regular inspections and audits are carried out by the local inspection authority.

Weholite LP Couplings

The Weholite LP Couplings are designed and manufactured specifically for use with Weholite pipes. Made from a high-quality stainless steel with a vulcanised rubber seal, these couplings are leak-free, corrosion resistant and easy to install, and if installed correctly, can have a design life of over 50 years.

Features & Benefits of Weholite

Virtually Leak Proof

12m lengths offer a greatly reduced joint frequency, which minimises the possibility of leakage or ingress of groundwater (which can lead to excessive loading of downstream treatment plants)

Corrosion Resistant

HDPE pipe is less susceptible to salt water and chemicals associated with sanitary sewage effluent and will not rust, rot or corrode

Flexible

Weholite has a high tolerance for harsh environments and is virtually unbreakable even in freezing conditions

Lightweight

HDPE construction pipes can be transported easily on site, often removing the need for heavy lifting equipment and significantly reducing its carbon footprint

Weld Ability

Weholite is suitable for fabrications of various pipe sheeting and Solid-Wall HDPE pipe, and other combinations. Welded joints render the sewer pipe 100% root ingress resistant.

Ease of Installation

Weholite Ease of InstallationEasier to Transport. Easier to Install. Reliable Joints

Owing to its light weight, Weholite HDPE pipe provides for easy installation, even in complex installations where challenging conditions are presented, often removing the need for heavy lifting equipment and reducing health and safety risks. In addition, the availability of 12m lengths offers a greatly reduced joint frequency, which minimises the possibility of leakage or ingress of groundwater (which can lead to excessive loading of downstream treatment plants).

Applications of Weholite

Irrigation

Weholite Structured Wall HDPE Pipe has proven to be an ideal solution in irrigation and low pressure water conveyance applications. The properties of Weholite, including strength and durability as well as enhanced hydraulic flow, ensure the installation of irrigation systems that will withstand the test of time.

Applications include: river and canal diversion, agricultural irrigation systems, underground irrigation systems, irrigation pipelines, water conservation and safety

Sanitary Sewer

For more than 50 years, polyethylene pipe has proven to be a reliable, long-term solution for sewer and wastewater systems. Weholite offers distinct chemical and physical advantages over other materials such as FRP, concrete and cast or ductile iron pipe. High flexibility and abrasion resistance means that it will not corrode or tuberculate over time, making it a long-lasting solution for municipal projects.

Applications include: sanitary interceptor sewers, sanitary sewer overflow, combined sewer overflow, aeration tank effluent and influent, final settling tank effluent and influent, plant effluent, tertiary filter effluent, and odorous air

Culverts

Deteriorating culverts come quickly become a problem when roadway damage caused by corroded, rusted and washed-out culverts occurs. Traditional culvert replacement methods are an expensive, time-consuming and labour-intensive process.

For years, Weholite has been considered the ideal choice for slip lining corroded culverts, since the slip lining process prevents traffic delays and road closures normally associated with traditional ‘dig and replace’ techniques. Weholite’s high axial stiffness and high resistance to the hydrostatic collapse pressurecaused by grouting, simplifies the installation and grouting procedures when using this pipe to reline deteriorated highway culvert pipe.

Drainage & Stormwater

Marley manufactures and supplies Weholite drainage systems for virtually any requirement in civil construction. In addition to enhanced hydraulic flow and unparalleled chemical and abrasion resistance compared with other materials – Weholite is unbeatable when it comes to flexibility in unstable ground conditions. In fact, research has shown that the service life of Weholite is 50% greater than concreate in stormwater applications.

Applications include: culverts, culvert relining, drainage pipe for building developments, drainage pipe for roadways and railways, stormwater drains, stormwater detention/retention

More applications include:

  • Cooling water intakes
  • Manholes
  • Pumping chambers
  • Marine outfall
  • Ventilation pipes
  • Surface drainage
  • Inter-process pipework
  • Tanks, floats, ventilation ducts
