sales. “Our extensive experience with the power generation and chemical processing industries has led us to the realisation that many situations require the strength and durability that only titanium can provide.” RathGibson, a PCC Energy Group Company, is a manufacturer of precision engineered straight lengths, coil and U-bend tubing for diverse industries such as power generation, renewable, oil and gas, petrochemical, chemical, food and dairy, beverage, pharmaceutical, and general commercial. Its US manufacturing locations include Janesville, Wisconsin; North Branch, New Jersey; and Clarksville, Arkansas (Greenville Tube). within each plug. Produced using layers of rubber reinforced with high quality aramid, the material can be applied more tightly so less fabric is required, resulting in a lighter and more flexible product. With new side handles incorporated into the design, the plugs are easier to handle and manoeuvre into position. The top plates are smaller in diameter, making transportation through tight manholes and difficult 90º pipe turns easier and quicker. The refined material application used within the new range will provide the plugs with an advanced ability to withstand high back pressures, reducing any concerns of plug failures. The multi-size, inflatable flow stopper range is available for underground pipe diameters ranging from 40 to 2,400mm, and can be specified with or without a bypass. The improved designs are expected to decrease the time taken to install and remove the plugs, as well as improve flexibility and safety. RathGibson – USA www.rathgibson.com

RathGibson, a manufacturer of welded, welded and drawn, and seamless stainless steel, nickel, titanium, and speciality alloy tubing, is connecting with the power generation and chemical processing industries by offering titanium tubing for heat exchangers, condensers and chemical processing applications. The tubing has the corrosion resistance and strength-to-weight ratio that make it suitable for operations in harsh environments, including seawater. RathGibson offers titanium grade 2 in wall thicknesses from 0.51 to 2.11mm (0.02" to 0.083"), with outer diameter sizes ranging from 12.7 to 38.1mm (0.5" to 1.5"). The light-walled tubing not only optimises heat exchange, but also reduces the overall operating costs.

A thin oxide film over the tube’s surface maximises corrosion resistance. All tubes are ASTM B338 and ASME SB338 certified, with excellent weldability for more flexible designs. “RathGibson has always and will continue to produce high-calibre tubing thatmeets our customers’ ever-changing needs,” said Greg Jones, director, CPI

New range of pipe plugs Trelleborg Offshore and Construction’s Infrastructure business, a global supplier of polymer-based critical solutions for deployment in highly demanding infrastructure environments, has launched a new range of pipe plugs that are lighter, safer and more flexible to install.

Trelleborg’s new production process means that the plugs are no longer fully manufactured by hand, resulting in a higher consistency of quality control and the ability to ensure finite detail

Jacco Vonk, business development manager within Trelleborg Offshore and Construction, commented, “Pipe closures for maintenance or construction work are a common occurrence in sewage systems, so it is important that they’re done quickly and efficiently to reduce delays or potential problems. In some instances, the pipe must be completely blocked off or the flow reduced. In these cases an inflatable stopper or pipe plug is ideal for the job. “In increasingly more challenging environments with even tighter budgets, it is important that working pipes are stopped for as little time as possible and concerns over difficult or unsafe installations are diminished. This is why we’ve invested heavily into the design and manufacturing processes of our pipe plugs, to create a product which is simpler for installers to fit and is safer once in situ.”
