TRANSCRIPT
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.
