Product Focus: Piping installation and repair

 

 

 

 

Resin  

 

Kynar® ADX resin is designed to bond together Kynar polyvinylidene fluoride and polyolefin resins in potable-water piping. The resin enables manufacturers to produce multilayer pipe, which utilizes the barrier properties of Kynar PVDF for other polymer structures. The polymer offers high chemical resistance, purity, abrasion resistance, and thermal resistance. Products can be melt-processed into pipe, fittings, valves, nozzles, and pumps, and can be cast into flat-sheet and hollow-fiber membranes or drawn into monofilament or multifilament fiber for wovens and nonwovens. The resin resists such cleaning and disinfection agents as bromine, chlorine, chlorine dioxide, ozone, peroxide, acids, and alcohols. Arkema Inc. (King of Prussia, Pa.). 

Gaskets 

The 3505 Gylon ® Stress Saver ® gaskets seal lightweight metallic, plastic, and fiberglass flanges that cannot provide the proper loads to compress conventional fiber or polytetrafluoroethylene gaskets. The molded, raised ribs enable a more concentrated gasket load, creating a tighter seal with less torque on both flat and raised-face flanges. In ongoing laboratory testing under controlled conditions, the gasket installed in fiberglass flanges has logged more than 3000 thermal cycles without leaking or having to be retorqued. Garlock Sealing Technologies (Palmyra, N.Y.). 

Rigid coupling  

SlideLOK™ rigid coupling is designed to enable fast, easy, and safe pipe installation. The installer simply lubricates the exposed gasket surfaces and slides the coupling completely over the pipe end, where it securely remains until the installer adds the adjacent component and slides the coupling into place. Other features include a patented coupling and pressure-responsive gasket with four separate sealing contacts that engage the groove all the way around the pipe. A specially developed leading edge eliminates gasket pinching, and the gasket lips facilitate easy slide-over. Anvil ® International (Atlanta). 

Press system  

The Victaulic PFT510 hand-held pressing tool is used to press couplings, fittings, or valves onto a pipe end, providing a positive mechanical interlock and creating a rigid, permanent, leak-tight joint. Patent-pending press-detection technology enables the installer to identify unpressed joints as the system is filled. The system requires 70% fewer man hours than welding to install. Unlike welding, no flame or arc is required for installation. Compared to flanges, couplings weigh less and feature a lower, boltless profile, enabling the system to be installed in tight spaces. Victaulic (Easton, Pa.). 

Pressure-reducing valves  

SRD pressure-reducing valves are designed to provide smooth, steady, and precise pressure control from maximum to virtually zero flow without the need for low-flow bypass valves. The effective area of a single rolling diaphragm remains constant, so the bonnet is much smaller and lighter than a flat-diaphragm version. A measured quantity into the bonnet control chamber gives the same smooth movement of the inner valve through the entire stroke. A smaller bonnet makes the valve lighter and safer for maintenance, while the smaller control chamber enables it to respond faster to changing pressures. By eliminating the seat chatter at low flows, the valve avoids injecting small pressure pulses, which, over time, may increase leakage, losses, or pipe bursts. Singer Valve Inc. (Surrey, British Columbia). 

Ball valves  

The PTP Series three-way PVC ball valve protects piping systems and reduces cost when diverting flow. Rather than use two two-way automated valves to control the flow of liquids, a single three-way valve does the job with fewer components. The valves are used for irrigation, wastewater, pool, water, filtration, and light-duty chemical applications. Assured Automation (Clark, N.J.). 

Secondary containment system  

The Contain-It Plus double-pipe system offers users a unique method of joining pipes to make installation easy. The inner pipe is joined first and subsequently pressure-tested. In a second step, the protective outer pipe is closed. The outer and inner pipelines can be joined and tested individually. Georg Fischer Piping Systems Ltd. (Schaffhausen, Switzerland). 

Valve  

The Series 300 Plunger Valve is designed with a valve-actuator mechanism that provides nonlinear closure with precise surge resistance and control ranges as high as 96%. The plunger’s O-ring seal, which is located outside of the cavitations zone, and four hard-faced cylinder support guides work together to help minimize wear and provide the valve with a longer operational life span. The valve’s input shaft features a dual inboard seal that helps protect the shaft and the shaft bore from corrosion. Henry Pratt Co. (Aurora, Ill.). 

Fusion machine  

The TracStar 500 Series 3 is capable of fusing thermoplastic pipes from 6-in. (iron pipe size) to 20-in. outer diameter (180 mm to 500 mm). The fusion carriage can be removed and lowered into a ditch for fusions in tight spaces. Power for the heater is supplied by an onboard generator, while a hydraulic-pump system driven by the engine provides the power for the facer, dual-speed track system, and more. Dual hydraulic pipe lifts help load and unload the pipe into the carriage. McElroy Manufacturing Inc. (Tulsa, Okla.). 

Pipe fittings  

ARC™ seamless high-density polyethylene (HDPE) bends are now available in 16-, 18- and 20-in. sizes. Fully pressure-rated and manufactured for angles ranging from 5 to 90 degrees, each bend is one continuous piece of HDPE with no mitered fusion joints and a seamless interior that creates virtually no flow restriction. Other features include increased wearability in slurry lines, as well as suitability for butt-welding, electrofusion, or flanging and no reversion. Pipestar International Inc. (Winnipeg, Manitoba). 

Restrained-joint PVC pipe  

The Certa-Lok™ C900 restrained-joint polyvinyl chloride pipe product line now includes an integral bell design option as well as a 14-in. size for larger diameter pipes for projects involving underground drinking water mains, reclaimed water, and force main sewers. Available in 4-, 6- and 8-in.-diameters, the Certa-Lok C900 RJIB (restrained joint integral bell) features a time- and field-proven mechanical pipe joining system, which utilizes a combination of precision-machined grooves and a nylon spline to provide exceptional tensile strength in pulling or pushing operations. Rounding out the design is a flexible elastomeric gasket within the integral bell to provide a solid pressure-certified hydraulic seal. The pipe does not require costly fusion or solvent welding and can be assembled in real-time as pullback continues, eliminating the need to string out several hundred feet of pipe within or beyond the work zone. CertainTeed (Valley Forge, Pa.) 

Turbine meter  

The FTB-630 series features nonresettable mechanical totalizers in 2-, 3-, 4-, 6-, and 8-in. pipe sizes. The turbine meters are manufactured of cast iron and epoxy-coated for protection. The durable, accurate, and cost-effective turbine meters have an optional pulse output and can be equipped with magnetic-pulse reed sensors for remote totalizing, pacing of electronic metering pumps, and water treatment applications. Omega (Stamford, Conn.). 

Composite fabric  

Agent-Q (patent pending) is a nonwoven composite fabric structure embedded with C.I.Agent solidifier. Specially developed for its high hydrocarbon binding and filtration capability, the fabric has no water flow restriction and is not dependent on water pressure. It offers businesses and industries a way to filter hydrocarbons, such as crude oil, gasoline, diesel fuel, solvents, or peanut and vegetable oils. The agent is an environmentally friendly blend of seven polymers, and it encapsulates and solidifies hydrocarbons on contact, turning them into a nontoxic, nonleaching rubberlike mass. C.I.Agent Solutions (Louisville, Ky.).
