What Primus Line does

Primus Line (legal entity: Rädlinger primus line GmbH) is a privately-held German specialty manufacturer of trenchless pipe rehabilitation and overland piping systems, founded in 2001 and headquartered in Cham, Upper Palatinate, Germany. The company designs and produces flexible, aramid (Kevlar) fibre-reinforced pipe liners and a proprietary connector family (M-, R-, and Q-Connectors) on a custom circular weaving loom at its Weiding production facility. Its technology enables rehabilitation of pressure pipelines (water, gas, oil) without open-trench excavation through single-piece liner installations up to 2,500 metres, and is the first and only DGUV-recognised low-emission method in Germany for asbestos cement pressure pipe maintenance.

The company serves four primary customer verticals — municipal water utilities, gas utilities, the oil & gas industry, and mining/industrial operators — across more than 60 countries, with three wholly-owned international subsidiaries in the United States (Charlotte, NC), Canada (Toronto), and Australia (Sydney) plus a certified installation partner network. Its business model combines hardware sales of liner and connector products with project engineering support, partner training, and recertification services, priced on a project-by-project basis rather than via public list pricing. Primus Line holds an unusually dense certification stack (DVGW, KTW-BWGL, NSF/ANSI/CAN 61, AS/NZS 4020, BS 6920, ISO 9001/14001/45001/50001) and has contributed to three technical standards governing flexible pipe liners.

The company operates within the family-owned Werner Rädlinger Gruppe and has grown organically over more than two decades to approximately 140 employees across technology development, production, and international sales. Its commercial model is enterprise field sales supported by certified installers, with no public pricing, no venture funding, and no plans for public listing in evidence.

Revenue model

1. Primus Line Pipe Liner and Connector Product Sales: Primus Line generates revenue through the sale of its proprietary flexible pipe liner products (W-Liner for water, O-Liner for oil, G-Liner for gas, F-Liner for flexible applications) and connector components (M-, R-, Q-Connectors). Products are sold internationally through direct sales teams and certified installation partners. The company also sells emergency kits and provides project planning and engineering support as part of solution delivery.
2. Project Engineering and Support Services: Primus Line provides project planning, engineering support, and installation supervision as part of its solution-oriented approach. Two in-house engineering teams support clients and partners through the project lifecycle. Training and recertification of installation partners is also provided, typically as part of the product-service package.

Core offering

Primus Line manufactures and sells flexible, aramid (Kevlar) fibre-reinforced pipe liners and proprietary connectors used for trenchless rehabilitation of pressure pipelines in water, gas, and oil applications, as well as reusable above-ground piping. Its two main systems are Primus Line® Rehab (no-dig rehabilitation of aging pressure pipelines) and Primus Line® Overland Piping (rapidly deployable, reusable surface pipelines). The product range includes four application-specific liners (W-Liner, O-Liner, G-Liner, F-Liner) and three connector types (M-, R-, Q-Connector), sold globally to utilities, municipalities, and industrial operators.

Product overview

Primus Line offers a unified pipe rehabilitation and overland piping system built around two core product lines: Primus Line® Rehab for trenchless pressure pipe rehabilitation and Primus Line® Overland Piping for above-ground pipeline solutions. The system is comprised of flexible pipe liners (W-Liner for water, O-Liner for oil, G-Liner for gas, and F-Liner for flexible applications) and specialized connectors (M-Connector mechanical, R-Connector resin, and Q-Connector quick/ Victaulic-compatible). These components work together as a complete rehabilitation solution where the aramid fibre-reinforced liner (Schlauchliner) is inserted into existing pipes and connected via purpose-designed connectors to form a new pressure-bearing pipe within the old pipe, without requiring excavation.
