Plate Flanges are among the most versatile and cost-effective connection components used in modern piping systems. At Jiangyin Zhonghai Precision Machinery Co., Ltd., we combine deep forging expertise with advanced machining to deliver high-quality plate flanges that exceed standard performance expectations.

By utilizing our in-house forging process—rather than simple plate cutting—we enhance the grain structure and mechanical integrity of every flange. From standard utility lines to massive 4-meter industrial installations, Zhonghai provides the engineering precision required for leak-free operations.

Core Advantages
·Certified Excellence: ISO 9001 certified with PED (EU) and TS (China) qualifications, ensuring full compliance with international pressure equipment safety standards.
 ·Full Vertical Integration: We manage the entire lifecycle—from raw material forging and heat treatment to CNC machining and lab testing—ensuring total quality consistency.
 ·Heavy-Scale Customization: Capable of handling single components up to 10 tons and diameters up to 4 meters, making us a preferred partner for heavy infrastructure projects.
 ·Multi-Standard Expertise: Seamless manufacturing according to ASME, DIN, JIS, EN, and GB standards to support global project procurement.

Key Features
·Enhanced Material Density: Unlike common plate-cut alternatives, our forged plate flanges offer superior internal structure and higher pressure resilience.
·Efficient Installation: The compact design allows for easier alignment and welding, significantly reducing on-site labor time.
·Superior Surface Finish: Precision CNC machining ensures that sealing faces (FF/RF) meet exact flatness and roughness specifications for zero-leakage performance.
·Versatile Metallurgy: Available in a wide range of carbon steels, stainless steels, and alloys tailored for specific corrosive or temperature environments.

Applications
Zhonghai Plate Flanges are widely deployed in the following sectors:
·Municipal Water Works: Urban water supply networks and wastewater treatment plants.
·HVAC Systems: Industrial cooling water loops and low-pressure steam piping.
·Light Industrial Machinery: Food processing, papermaking, and packaging equipment.
· Power & Energy: Auxiliary pipelines, storage tank interfaces, and non-critical pressure systems.
·Environmental Engineering: Exhaust gas treatment, dust collection, and desulfurization systems.
