Nippon Pipeline Service Co., Ltd. (NPS)

What Nippon Pipeline Service Co., Ltd. (NPS) does

Nippon Pipeline Service Co., Ltd. (NPS), founded in December 1969 in Tokyo, is Japan's oldest specialized pipeline pigging contractor and exclusive Japanese distributor for three principal Western manufacturers: Knapp Polly-Pig (since 1969), Inline Services (since 1993), and Maloney Technical Products (since 1990). The company's core capability is polyurethane-foam-pig-based cleaning, flushing, decoking, and product-switching of industrial pipelines for oil refineries, petrochemical plants, food factories, oil terminals, and municipal water systems, both domestically and across Vietnam, the Philippines, Papua New Guinea, Indonesia, and Thailand. Technical assets include the in-house-developed K20 special decoking pig (for hard carbon and iron sulfide removal in furnace tubes), a pig locator tracking system, and records including a 34km single-run pipeline flush and 1,400mm pipe diameter work. NPS holds Quest Integrity Group's "APPROVED CONTRACTOR FOR PIGGING CLEANING" designation, food-grade pigs compliant with Ministry of Health and Welfare Notification No. 370, and Tokyo Metropolitan Construction License No. 135769.

The company generates revenue through four streams: (1) construction services — pipeline pigging, new-pipe pre-commissioning flushing, existing-pipe maintenance, oil removal/product switching/degreasing, and furnace decoking, performed by its own staff plus partner subcontractors; (2) one-time product sales of POLLY-PIG variants, city-water poly pigs, closures, and detectors sourced from Knapp, Inline Services, Maloney, GD Engineering, MODOCO, Tube Turns, and Apache; (3) equipment leasing of launchers, pig tracking systems, and dust bags; and (4) pigging system design and consultation, including DCS/PLC signal specifications, launcher/receiver engineering, and pig selection.

NPS is privately held, founder/management-controlled (CEO Taketomo Sagawa, 佐川岳丈, since founding), with registered paid-in capital of ¥10 million (~$67K USD), approximately 10 employees, no disclosed external funding, no subsidiaries, and no parent company. Go-to-market is enterprise field sales via direct engagement with engineering companies and plant operators; pricing is quote-based on pipe specifications, fluid type, and pushing medium, and is not publicly disclosed. Marketing relies on the bilingual website (pigging.jp), downloadable catalogs, and project-quality referrals rather than broad digital channels.
