Cherne Introduces World’s Largest Test Ball
Cherne Industries, part of the Oatey Co. family of companies, introduced the world’s largest Test-Ball Plug.
The 72- to 120-inch Test-Ball was carefully developed with an optimized design that offers improved performance and safety for blocking flow in the biggest pipes in sanitary and storm sewer systems.
Accommodating a back pressure of up to 6 psi, the plug weighs 850 pounds and is 152 inches long. It is made from tough, tear-resistant natural rubber and features ¾ inch eyebolts that provide superior holding strength. A field-replaceable pressure relief valve prevents over-inflation, and an aluminum end plate minimizes rust and corrosion.
“When job-site conditions call for a test plug of this size, we know safety and performance are of the utmost importance,” said Cassandra Alverson, product manager at Cherne. “That’s why we’ve engineered the world’s largest test plug with the same quality control and manufacturing standards that Cherne is known for around the world.”

Vortex Enhances, Expands UV CIPP Solutions
The Vortex Companies, a leading provider of advanced trenchless water and sewer technologies and infrastructure renewal services, introduces its new, comprehensive UV CIPP Systems solutions portfolio. Vortex’s UV CIPP curing equipment systems, liners, and custom truck builds backed by expert training and support, enable the company to be a valuable partner in the rehabilitation of aging infrastructure.
Commonly used in Europe, UV CIPP provides contractors, engineers, and asset owners with a proven approach to expand their existing use of CIPP technology in a way that allows additional installation flexibility and environmental advantages. Vortex offers the most advanced UV curing equipment options available through its strategic partnership with IMS Robotics. Accommodating pipe diameters 6 inches to 80 inches.
Vortex’s new EnviroCure UV Liner, developed in partnership with Applied Felts, is pre-impregnated with resin and constructed using a corrosion-resistant, styrene barrier sleeve, non-wicking fiberglass to enhance physical strength while delivering a thinner pipe wall design. Its unique construction enables reinstatements to be performed quickly and correctly the first time with reliable dimpling that clearly identifies junctions between laterals and the main line, saving several minutes per lateral to return assets to service faster.
Additionally, the liner is cold and hot weather-friendly, ideal for environmentally-sensitive locations, manufactured in the
USA and readily available – as quickly as two weeks–to speed project completion.
Small Diameter UV
Vortex has also announced the addition of the small diameter IMS MICROcure LED CIPP Curing System (MICROcure) to its portfolio of UV CIPP solutions. Source One Environmental (S1E) is Vortex’s exclusive distribution partner in the United States for the technology.
MICROcure is specifically engineered to reline sewer mains, laterals, and interior plumbing systems ranging from 3- to 10-inch diameter, and works with both inversion and CIPP methods. Designed for portability, MICROcure is built on a two-wheel carriage and weighs only 176 pounds.
The system comes with two light sources for optimum curing: a 2x400-watt unit that easily navigates multiple bends up to 90 degrees for three to 6-inch pipe, and an 8x100-watt unit that accommodates six to 10-inch pipes.

SAERTEX Achieves Liner Installation Milestone
At the end of 2022, SAERTEX multiCom GmbH, successfully delivered and installed its100,000th pipe liner, in cooperation with Spanish sewer rehabilitation specialist STLIMA.
The project, in downtown Valladolid, a major city in northern Spain, was to rehabilitate a dilapidated section of sewer with an egg-shaped profile. It is part of a comprehensive rehabilitation of the Valladolid sewer network for local network operator Aquavall.
Since the start of construction work in 2019, 49 kilometers of wastewater and stormwater pipes have been rehabilitated using the trenchless method, which was carried out using the existing manholes of the sewer system. By eliminating earthwork and tree felling, this method reduces the environmental and everyday life impacts of other methods, such as noise, dust and traffic disruption.
A 1,200-by-800-millimeter, 98-meter-long liner made of glass fiber reinforcements, pre-impregnated with resin, was pulled into the host pipe, set up with compressed air and cured by means of a UV light chain.
An advantage of rehabilitating with glass-fiber-reinforced pipe liners is the technical service life of a pipeline is designed for 50 years.
Based in Saerbeck, Germany, and
founded in 1996, family owned SAERTEX multiCom develops and produces numerous products for the trenchless rehabilitation
of municipal and industrial sewers, as well as drinking water pipes.
“We are particularly pleased with the successful installation of this anniversary liner,” said Kai Diecks, Global Managing Director at SAERTEX multiCom. “Because even though this SAERTEX-LINER was tailor-made for the project in Valladolid, over the past 27 years we have managed to make trenchless rehabilitation already state-of-the art in many countries around the world – and thus part of everyday life in many rehabilitation projects.”
