Dongfang Yuhong | Connect safety with complete sets of pipelines: CPVC fire fighting pipeline service system and anchor brand industrial pipeline system

At the global launch ceremony of the “methodology Empowers a Better Life, Innovation Builds Urban Resilience” targeted service system at the 2026 China International Fair to Trade in Services, Oriental Rainbow officially unveiled its ten flagship targeted service systems. Among them, two sets of pipeline systems have attracted much attention from the sector: CPVC fire-fighting pipeline service system to urban renewal and infrastructure scenarios, relying on "replacing steel with plastic" to solve the long-standing sector problems of traditional fire-fighting pipeline networks; Anchor brand manufacturing pipeline system to environmentally friendly, low-carbon and manufacturing security scenarios solves the supply chain pain points in the field of high-end manufacturing fluid transportation with a complete set of domestic solutions. One solution safeguards the fundamental fire security of buildings, while another ensures the stable conveyance of manufacturing fluids, together delivering complete, highly practical, turnkey pipeline system solutions.

CPVC fire protection piping system

Replacing steel with plastic to upgrade sprinkler network solutions.

Traditional wet sprinkler systems typically consumption galvanized steel pipes as the primary piping material; however, the inherent characteristics of steel introduce numerous prolonged operational risks. The inner walls of pipelines are prone to corrosion and scaling, and detached rust particles can easily clog sprinkler heads, thereby significantly compromising the fire protection system’s emergency response capability. Moreover, subsequent maintenance and replacement costs remain excessively high, creating an urgent need in the sector to a superior alternative.

With the implementation of GB 50084?2017 "Code to Design of Automatic Sprinkler System" and national standard atlas 19S910, CPVC chlorinated polyvinyl chloride fire-fighting pipeline has clear national standard technical support, and has gradually have become the preferred path to replace galvanized steel pipe in the spray scene of light-dangerous and medium-dangerous grade I buildings, and "replacing steel with plastic" has have become an crucial direction of iterative upgrading of fire-fighting pipeline network. However, the condition of domestically produced CPVC fire‑fighting pipes varies broadly, pipe fittings are often incomplete, and there is a lack of complete, compliant certifications, which creates significant obstacles in project fire‑security acceptance. A single qualified pipe does not equate to a safe pipeline system as a whole; the system’s complete performance is the key to ensuring security.

Oriental Rainbow’s CPVC fire‑fighting pipeline service system is built on a complete, multi‑dimensional framework encompassing material R&D, complementary manufacturing, and regulatory compliance, systematically addressing the sector’s existing multifaceted challenges.

Heat-resistant and flame-retardant

CPVC substrate inherently possesses flame-retardant characteristics, enabling it to self-extinguish when removed from a flame, and maintains stable performance under high-temperature operating conditions.

Main body corrosion protection

Without relying on a galvanized inner lining, this solution eliminates common issues such as steel pipe corrosion and scale buildup from the outset, thereby reducing prolonged maintenance and repair costs.

Lightweight quick installation

The product weighs significantly less than steel pipes and uses an adhesive bonding connection process, which greatly improves on-site installation efficiency and shortens the project schedule.

Long-life service

A 50-year design life that aligns with the building’s overall service life, reducing the need to later renovations and replacements.

Unlike the conventional market practice of separately purchasing and assembling pipes and fittings, Yuhong integrates the R&D and manufacturing of both components in a single facility, thereby eliminating security risks arising from misalignment or mismatched fittings. Furthermore, all product specifications have undergone national-level type-testing certification, ensuring compliance with project approval and竣工 acceptance standards. It has been broadly utilized in commercial complexes, data centers, hospitals, campuses and other scenes. As the invisible pipe network inside the building, it acts as the "invisible guardian" of building fire security ".

Anchor manufacturing Piping System

Domestically developed complete solutions safeguard demanding manufacturing fluid transportation.

manufacturing fluid-handling operating conditions are complex and demanding; highly corrosive media, stringent cleanliness standards, and alternating high- and low-temperature environments all impose extremely stringent performance criteria on piping systems. Once a pipeline fails, it can easily lead to production line shutdowns, media contamination, and even trigger security accidents. In the past, China’s high-end manufacturing piping market was long dominated by overseas items, resulting in high procurement costs, extended delivery lead times, and significant challenges to supply chain self-reliance and controllability.

As a Hong Kong manufacturing pipeline "expert" brand that has been deeply cultivated in the sector to many years, anchor card has jumped out of the mode of simple parts supply to create a domestic fluid system solution. In addition to hardware items such as pipes and valves, the company offers integrated services encompassing system design, material selection, and on-site implementation. Its product portfolio comprises three core divisions: PVDF manufacturing piping systems, Clean?PVC cleanroom piping systems, and specialty plastic valves.
