Tak Setareh Golpayegan Industrial Group (TG)
Tak Setareh Golpayegan began in 2003 with U-PVC pipe and fitting production. By innovating in extrusion and injection molding, the Group quickly became a leading player in Iran’s piping market. With Negin Setareh Golpayegan (2010) and Alborz Setareh Golpayegan under the Nivan Pipe brand (2013), the portfolio expanded to polyethylene, PP-R, push-fit systems, and multilayer pipes.
Subsidiaries & Product Diversity
| Company | Year | Core Expertise | Brand |
|---|---|---|---|
| Tak Setareh Golpayegan | 2003 | U-PVC pipes & fittings | TG |

Manufacturing Technology & Quality Control
Three pillars drive TG quality: European precision molds, premium-grade resins, and an in-house fluid-mechanics & pressure lab (tests up to 20 bar). Each shift includes online wall-thickness monitoring, impact testing, and ring-stiffness (RS) checks to ensure dimensional consistency and long-term performance.
