POLYPIPE: THE SINGLE SOURCE FOR TOTAL SYSTEM SOLUTIONS |  |
||||||||||||||
| Typical Applications |
Ease of Handling and Installation Lightweight PolyPipe weighs less than one fourth of comparable steel pipe. Significant savings can be realized in transportation, handling and installation. Pipe diameters up to 4" can be coiled for ease of handling and storing. PolyPipe is quickly and easily joined using the heat fusion method or special polyethylene mechanical fittings. Heat fusion produces a solid, leak proof joint as strong as the pipe itself. |

| Moving fluids through pipe in the oil field demands the utmost in flexibility, reliability and performance. That's why PolyPipe is your best choice for the energy business. Our HDPE (high density polyethylene) piping provides superior flow characteristics, extended life and durability and reduced maintenance than traditional piping materials, anywhere in the oil patch.
We offer a wide selection of pipe, fittings and valves as a single source, to meet your needs for any oil field application. As a leader in the pressure rated pipe industry, PolyPipe features a network of sales offices around the world. Our eight U.S. manufacturing facilities are regionally located to assure timely, accurate delivery to any location you require. |

| POLYPIPE: The Advantage in The Field | |||||||||||||||||
| Cost Effective Significant cost savings should be expected over traditional pipe materials (steel, fiberglass, PVC) within the same design parameter. Savings accrue both on initial product cost and by improved installation efficiency.
Chemical and Abrasion Resistant PolyPipe is extremely resistant to most chemicals and corrosive elements / It's also extremely tough and resistant to abrasive elements and stress cracking. Superior Flow Characteristics With a "C" factor of 150 by the Hazen-Williams equation, our pipe offers exceptionally smooth inner surface, and heat-fused joints offer little drag or resistance within the pipe. In some situations, clients may be able to downsize the pipe and maintain a comparable flow rate of larger traditional piping. Flexibility and Resiliency PolyPipe can bend to a radius of 20 times the pipe diameter allowing pipe to bend around obstructions without splicing or special fittings. Weatherability HDPE 3408 Black PolyPipe is designed to withstand extended outdoor storage and above-ground use in most climates. Black PE pipe has a minimum of 2% finely dispersed carbon black; the most effective additive for protecting polyethylene from the effects of weathering. |

| Liquid Flow For PolyPipe | |||||||||||||||||
| For liquid flow , PolyPipe recommends the Hazen-Williams equation. The constant for the pipe roughness factor is 155. Thus, the equation for liquid flow would be:

| Gas Flow Curves For PolyPipe | |||||||||||||||||
| The flow formula for smooth pipe should be used to compute the gas flow rate through PolyPipe. It has been found that the Mueller formula for smooth wall pipe describes the flow characteristics of PolyPipe.

| Water Hammer and Pressure Surge: PolyPipe Can Take It! | |||||||||||||||||
| The momentum, or inertia, of a moving column of liquid has an inherent characteristics that must be dealt with in a piping system, When liquid flow is stopped suddenly, as by a quick closing valve, the inertia is converted into a shock wave or high pressure surge. The faster the liquid velocity and the longer the line, the greater the shock load. Controlled dissipation of this energy is a design feature and significant advantage of the polyethylene pipe from PolyPipe. | |||||||||||||||||
