Technologies Infrastructure Solutions The company’s Insituform CIPP process (including Insitupipe and Insitutube) for the rehabilitation of wastewater pipelines and other conduits utilizes a custom-manufactured tube, or liner, made of synthetic fiber. After the tube is saturated (impregnated) with a thermosetting resin mixture, it is installed in the host pipe by various processes. The resin is then cured, by heat (hot water or steam) or ultraviolet light, forming a new rigid pipe within a pipe. The company’s iPlus Infusion pull-in CIPP is a trenchless method for the rehabilitation of small-diameter wastewater pipelines, whereby a felt liner is continuously impregnated with liquid, thermosetting resin through a proprietary process, after which the liner is pulled into the host pipe, inflated with air and cured with steam or ultraviolet light. The company’s iPlus Composite CIPP is used for the trenchless rehabilitation of large-diameter wastewater pipelines, where the felt liner is reinforced with carbon or glass fiber, impregnated with liquid, thermosetting resin, inverted into place and cured with hot water or steam. The company’s InsituMain CIPP system is a solution for pressure pipes, including water mains and force mains approximately 96-inches in diameter. The system could negotiate bends and is pressure-rated approximately 150 psi. The InsituMain system has also been certified as complying with NSF/ANSI Standard 61. The company’s Insituform RPP process is a trenchless technology used for the rehabilitation of wastewater force mains and industrial pressure pipelines. The felt tube is reinforced with glass and impregnated with liquid, thermosetting resin, after which it is inverted with water and cured with hot water to form a structural, jointless pipe within the host pipe. The company’s Insituform PPL process is a trenchless technology certified to NSF/ANSI Standard 61 used for the rehabilitation of drinking water and industrial pressure pipelines. A glass-reinforced liner is impregnated with an epoxy or vinyl ester resin, inverted with water and cured with hot water to form a jointless pipe lining within the host pipe. The company’s Thermopipe system is a non-disruptive pressure pipe rehabilitation system used for potable and non-potable water mains whereby a high tenacity polyester reinforced liner is winched into a host pipe from a reel and inflated with air, forming a close-fit, jointless, leak-free lining system able to independently carry the full system design pressure. The company’s iPlus Glass UV system is a CIPP solution for small- to medium-diameter pipes utilizing a glass fiber tube that is impregnated with a resin sensitive to ultraviolet light. The tube is pulled into place in the host pipe, inflated by air and cured through an ultraviolet light source. The company’s iPlus Felt UV system is a CIPP solution for small- to medium-diameter pipes utilizing a 100% felt tube that is impregnated with a resin sensitive to ultraviolet light. The tube is pulled into place in the host pipe, inflated by air and cured through an ultraviolet light source. Sliplining is a method used to push or pull a new pipeline into an old one. With segmented sliplining, short segments of pipe are joined to form the new pipe. For gravity wastewater rehabilitation, these short segments could be joined in a manhole or access structure, eliminating the need for a large pulling pit. The company’s iTap is an internal service line reinstatement process that includes associated fittings, robotics and control systems for leak free connections in CIPP lined potable water mains. The company’s Fusible PVC technology contains proprietary PVC formulation that, when combined with its patented fusion process, results in a monolithic, fully-restrained, gasket-free, leak-free piping system. Fusible PVC pipe products include Fusible C-900 and FPVC pipes. Fusible C-900 pipes comply with the AWWA C900 standard and are certified to the NSF/ANSI Standard 61. The company’s Tyfo Fibrwrap system is a series of high-strength, light-weight fiber reinforced polymers used to strengthen structures, including columns, walls, slabs, beams and large diameter pressure pipelines. Beyond general strengthening of pipelines and structures, the Tyfo Fibrwrap system also has applications in blast mitigation and seismic retrofits. Corrosion Protection The company’s Tite Liner system is a method of lining new and existing pipe with a corrosion and abrasion resistant thermoplastic pipe. The company’s Safetyliner product is a grooved thermoplastic liner that is installed in an industrial pipeline using the Tite Liner process. The Safetyliner liner is used in natural gas or CO2 pipelines to allow the release of gas that permeates the thermoplastic liner. If gas is allowed to build in the annular space under normal operating conditions, the line could be susceptible to collapse upon sudden changes in operating pressures. The Safetyliner liner also has been used in pipelines as a leak detection system and for dual containment in mine water pipelines. The company’s rotational lining process bonds a uniform polymer layer to the interior of any metallic structure, regardless of shape and complexity. This result is achieved by placing granular resin inside the structure to be lined and all openings are covered. The structure is then heated while simultaneously being rotated approximately two axis. The resin melts and flows evening over the entire inner surface of the structure, bonding to the metal substrate. Once cooled, the result is a monolithic corrosion and chemical resistant lining that conforms to complex shapes and is free of stresses. The company’s WeldTite family of products allows for the connection of individual lined pipe sections through the use of welding rather than the industry standard of bolted flange connections. This provides a level of assurance against leaks and allows United Pipeline Systems to utilize its liner systems in customer locations, such as environmentally sensitive areas or offshore where flanges are generally not allowed. The company’s PreFIT product line offers customers thermoplastic lined steel pipe in sections short enough to be manufactured, transported, and then inventoried at a customer’s location. This allows customers control of their pipeline production schedules when compared with standard on-site liner installation processes. The company’s fusion bonded epoxy pipeline coating utilizes heat to melt a dry powder FBE coating material into liquid form. The liquid material flows onto the steel pipe and solidifies through a process called cross-linking. Once cooled, this ‘fusion-bonded’ epoxy cannot return to its original state and forms a corrosion protection barrier on the interior or exterior surface of the pipe. The company’s 3-layer polyethylene coating is an external coating for buried or submerged oil or gas pipelines and offers adhesion, cathodic disbondment resistance and mechanical protection. The company’s deepwater coating and insulation capabilities answer the challenge of subsea wet insulation requirements for high-pressure and high-temperature environments. Applications include subsea equipment and field joints for coating the girth welds where the pipe coating has been cutback to allow for welding joints of pipe. The company’s internal field joint coating technology consists of self-contained robots that travel inside the pipe, find the weld and then clean, vacuum and coat the area. Utilizing various cameras, these field joint coating robots transmit a real-time video image back to the operator, which is then used for control and inspection. The technology allows for the field application of FBE and plural component liquid materials to the weld area. The company’s liquid coating services offer an array of plural component and multi-layer corrosion coatings. These coatings could be applied to protect metallic substrates of geometry, including pipeline equipment and manifolds. Cathodic protection is an electrochemical process that prevents corrosion of new structures and stops corrosion on existing structures. Metal loss is prevented by the passing of a direct current from a cathodic protection electrode (anode), through the electrolyte (soil, water, concrete, etc.) on to the structure to be protected (cathode). In this process, the anode corrodes, sacrificing itself to protect the integrity of the cathode. Structures commonly protected by this process include oil and gas pipelines, offshore platforms, above and underground storage tanks, ships, electric power plants, bridges, parking garages, transit systems and water and wastewater facilities. The company’s CorrFlex system is a linear anode system installed parallel to pipelines, oftentimes to prevent stress corrosion cracking that could lead to ruptures on high pressure gas transmission pipelines. The company’s CorrSpray product provides a solution for preventing corrosion of steel reinforcements in concrete structures. The company’s Corrpower DC power supplies include designs, as well as remote monitoring and control capabilities. The company’s Green Rectifier system is an ecologically friendly method of cathodic protection using solar panels and a wind generator to power the cathodic protection process. The company’s Permanode product is a submerged anode system and it is the industry standard for internal water tank cathodic protection designs. The company’s Grid system has set the global standard for preventing releases from external corrosion of at-grade storage tanks containing oil and petroleum products, thereby ensuring operations and protection of the environment. The company’s AC interference mitigation solution protects pipeline operators and the public from electrical hazards when pipelines share space on rights-of-way with overhead electric transmission lines. Beginning with advanced predictive modeling, the company then designs mitigation schemes and provides systems to protect people and the pipeline. The company’s asset integrity management (AIM) platform allows for the collection, communication and storage of data in the cloud using a geospatial information system-based, centralized, integrated repository that provides it and its customers information and improved data analytics. Data collection applications include LiveLine and CISView, data delivery applications include AssetView and FieldLine, and data analytical tools include ScanLine and ChargeLine. The company’s Correlator data collection system electronically records corrosion protection data on its customer’s assets, then transmits and stores the data in its AIM platform for compliance reporting and advanced analytics.
