What is the range of pipe sizes extruded in Peak Pipe Systems?

50 to 450mm

What is the difference between PE80 and PE100?

PE80 and PE100 are both types of polyethylene. Pipe made from PE100 is mechanically stronger and gives a greater pressure rating than PE80 for the same SDR (i.e. 250mm SDR 11 PE100 is 16 bar rated. 250MM SDR11 PE80 is 12.5 bar rated).

What is SDR? Why is it important?

Standard dimension ratio (SDR) is the ratio of the nominal outside diameter of a pipe to its nominal wall thickness. It is important to select the correct SDR as this determines the pressure rating of the pipe.

Can you extrude pipe using recycled polyethylene?

Yes. Recycled polyethylene is used by Peak Pipe Systems to extrude pipe for non-pressure applications. Peak Pipe Systems always uses virgin polymer for PE100 pressure pipe applications.

How does the wall thickness of pipe impact on its pressure rating?

The greater the wall section the higher the pressure rating

I've seen black pipe with a green stripe. What is it used for?

Pipe with green stripes is used for rainwater harvesting

What lengths of pipe am I able to order?

The extrusion process is continuous, so in theory any length of pipe is possible. Transport tends to be the practical limiting factor. 6m lengths are the industry standard, but it is possible to transport 13.5m long pipes on a 40' truck. The longest pipes extruded and delivered by Peak Pipe Systems are 18m long.

Commercial

Do you do next day deliveries?

Yes. We keep a stock of common pipe sizes and standard fabrications. If the order is placed before midday and the product is in stock you will get it next day.

Do you have national coverage?

Yes. We operate a series of 'milk round' deliveries across the country

Can you help me unload my pipe and fabrications?

Yes. Peak Pipe Systems has vehicles with hi-ab attachments to enable heavy items to be unloaded.
