What Inline Services does

Inline Services, LLC is a Tomball, Texas-based manufacturer and service provider of pipeline pigging equipment, founded in 1992 and operating as a division of Critical Infrastructure Holdings. The company designs and produces a portfolio of pipeline pigs — including Speed Control Pigs (SCP) with onboard IMU and 1.5D short-radius bend capability, steel mandrel pigs, cast urethane pigs, polyurethane foam pigs, pipeline spheres, and custom-built cleaning pigs — complemented by pig parts and accessories (discs, cups, brushes), tracking and detection equipment (transmitters, receivers, sensors, geophones, IK non-intrusive pig signallers), and the VIPRS product recovery system for sanitary and industrial applications. Inline Services is the exclusive U.S. distributor for the Apache pigPRO intrusive pig passage indicator and offers related services spanning budgeting/planning/design, pipeline integrity and cleanliness assessment, intelligent pipeline cleaning, and operational support.

The company's business model combines hardware sales (pipeline pigs, parts, tracking equipment, product recovery systems) with professional services and equipment rental, distributed primarily through a direct sales model supported by a toll-free line, website quote requests, and a sales team that exhibits at industry conferences such as PPIM and ADIPEC. Pricing is quote-based and not publicly disclosed; a Pigging ROI Calculator is provided to support customer evaluation. Customer segments span Oil and Gas (primary), Food and Beverage, Refining and Chemical, Offshore, Water Treatment, Process Manufacturing, Wineries, Petroleum Distribution, and Pharmaceutical — with oil and gas pipeline operators and pigging contractors as the principal buyers. Growth has been pursued through organic product launches (SCP, Custom Urethane Products division), acquisitions (First Call Enterprises in 2020; Sun Pipeline Solutions and Winterhawk Pipeline Services in 2022), and strategic partnerships (EV Cam collaboration announced in late 2025 for combined visual-analytics inspection services).
