With the current tough economic climate and challenging 2010-15 price settlement, water companies and contractors are under increased pressure to find opportunities to lower pipeline costs, which form a major part of their capital expenditure.
As material costs can contribute to a significant part of the pipeline costs, there is an increased temptation for to opt for the cheapest pipe. There are, however, opportunities for designers to reduce costs without compromising on quality.
Choose Polyethylene

The past 40 years have demonstrated that, time and again, polyethylene delivers the best value in comparison with other pipeline materials. The attributes that make مشاهده لینک ها و تصاویر پس از ورود یا عضویت the most cost-effective material have been discussed at length in other articles and can be summarised as follows:
Durability
♦ Lifetime (in excess of 100 years)
♦ Absence of corrosion
♦ No lining to deteriorate
♦ Fewer leaks, cracks and failures
♦ Joint welds stronger than the pipe itself
♦ Pipes absorb stress caused by ground settlement

Installation
♦ Jointing options (without anchor blocks)
♦ Light and flexible for easier handling
♦ Long pipe lengths handled by excavator – fewer joints
♦ Narrower trenches
♦ Trenches closed quicker
♦ Compatibility with no-dig methods

Performance
♦ Smooth bore maximises flow and reduces fouling
♦ Consistent pressure and flow characteristics
♦ Minimal maintenance
