Introduction

Low dens i ty po lye thy lene p ipe is

manufactured in South Africa traditionally

using scrap material from recycling plants . A

SABS approved pipe using virgin material is

also available for discerning end users but

this is not the norm.

Areas of application

LDPE pipes can be used in a wide range of applications

including sprinkler and drip irrigation systems, drainage

systems, , agricultural piping and irrigation systems .

The pipe is used with Full flow and nylon insert fittings like

couplings , elbows tees and adaptors .

The pipe is measured internally as opposed to HDPE which is

normally measured by the outside diameter

Installation

Low density pipe and fittings can be installed using very simple

equipment . As all the fittings are fitted internally pipe should be

warmed up before insertion of a fitting to assist with swelling

the pipe over the fitting . Pipe is then secured by clamping it

down onto the pipe with a worm screw type clamp .

Low density pipe can be buried or secured above ground . The

pipe is normally UV resistant and is also resistant to most

chemicals like fertilizers etc. The worm screw clamps should

be protected if the product is being used in a area of high

humidity or if exposed to chemicals .

Working pressures

Low density polyethylene pipes are manufactured in two

pressure ranges namely PN 3 and PN 6.
