If you are building a house, managing a construction project, or specifying materials for a high-rise development, the pipes you choose matter more than most people realize. Bad pipes leak, corrode, or fail under pressure. Replacing them mid-project or post-construction costs far more than getting it right the first time. This is where experience, quality, and proven reliability make a difference.

CROWN Pipes, manufactured by CROWN Asia Chemicals Corporation, has been producing pipes and fittings in the Philippines since 1989. With more than three decades of manufacturing excellence, CROWN has continuously advanced product development and delivered reliable solutions across residential, commercial, industrial, and infrastructure sectors.

CROWN Asia Chemicals Corporation is an ISO 9001:2015 certified Philippine manufacturer listed on the Philippine Stock Exchange (PSE). It produces PVC compounds, uPVC pipes and fittings, PP-R piping systems, HDPE solutions, electrical and telecom conduits, thermal roofing systems, grease management solutions, and advanced wastewater treatment systems.

Here's a closer look at what sets CROWN Pipes apart and the comprehensive range of piping and infrastructure solutions it offers for residential, commercial, industrial, and infrastructure applications.

The CROWN Pipes Product Line

  • Crown Supreme Thick Wall — for installations that need heavy protection
  • Crown Hi-Tech Thin Wall — for standard electrical conduit work

Both variants are highly flame-retardant and self-extinguishing, meaning they stop burning when the ignition source is removed. They comply with PNS-14, the Philippine National Standard for electrical conduit pipes. Electricians and electrical engineers specify these for residential, commercial, and industrial wiring installations.

9. CROWN Telecom (ASTM F512 / NEMA TC-6/TC-8)
