Founded in 2012 and headquartered in Xinxiang City, Henan Province, China, Zhisheng Metal has built a comprehensive operational system integrating R&D, manufacturing, quality control, and global sales, supported by a 50,000-square-meter modern production base and 170 professional and technical talents. The company’s core mission is to provide the global HVAC industry with high-reliability, energy-efficient, and technologically advanced copper components, and its air conditioning branch pipes stand out as a flagship product embodying this commitment.
As a critical component in VRF systems, the air conditioning branch pipe is responsible for precisely distributing refrigerant from the outdoor unit to multiple indoor units, playing a vital role in ensuring the stable and efficient operation of the entire HVAC system. Unlike ordinary tees that often cause uneven refrigerant distribution and system failures, Zhisheng’s branch pipes are specially designed with optimized internal flow channels based on fluid mechanics principles, effectively avoiding "flow deviation" and ensuring proportional distribution of gas-liquid two-phase refrigerant to each indoor unit .
Zhisheng’s seamless branch pipes, a core product of the company, boast outstanding technological advantages backed by multiple invention patents. The key innovation lies in the elimination of welding points, achieving an ultra-smooth inner wall that reduces refrigerant friction loss by 15%, significantly improving HVAC system efficiency and reducing energy consumption. Crafted from high-grade copper materials including C12200 (TP2) deoxidized copper and C11000 pure copper with a copper purity of ≥99.95% and a thermal conductivity of ≥401 W/(m·K), these branch pipes exhibit excellent corrosion resistance and mechanical properties, capable of withstanding harsh working conditions such as high pressure, high temperature, and corrosion.
Safety and compliance are at the forefront of Zhisheng’s branch pipe production. The company adheres to the highest international standards, holding ISO 9001:2015 quality management system certification, and its branch pipes meet the requirements of global standards such as ASME, JIS, ASTM B280, EN 1254, and GB/T 19228 . Notably, the branch pipes for R410A and R32 refrigerants, which require a high-pressure test of at least 4.15MPa, can easily withstand 10MPa to 18MPa. Each unit undergoes a rigorous 16MPa pressure test, with an ultimate pressure resistance of 25MPa (holding pressure for 30 minutes without leakage or rupture). For R32 refrigerant systems, all welding points undergo 100% helium leak testing to ensure the safe operation of A2L refrigerants.
In terms of compatibility and customization, Zhisheng’s branch pipes are fully compatible with major international HVAC brands, including Mitsubishi, Daikin, Hitachi, Gree, Hisense, Samsung, Panasonic, LG, and Haier. The company offers brand-specific branch pipes, such as those meeting Daikin’s ASHRAE 15 standard and Mitsubishi’s M-series requirements. Additionally, flexible OEM/ODM customization services are available, covering personalized needs such as size, material, refrigerant adaptation, brand-specific structures, and private label customization. The standardized customization process – from demand docking and feasibility analysis to design optimization, sample confirmation, and mass production – ensures efficient and accurate delivery of customized products.
Supported by advanced manufacturing capabilities, Zhisheng’s 50,000-square-meter production base is equipped with high-end automated production lines and advanced processes such as seamless forming, precision CNC machining, stamping, extrusion, and polishing, ensuring consistent quality and large-scale production. The monthly output of standard components can reach 500,000 pieces, with flexible production capacity expansion to meet peak demand. The company’s efficient logistics network enables timely delivery via air, sea, and land transportation to more than 60 countries and regions across North America, Europe, Asia, Australia, and South America.
“Our air conditioning branch pipes are the result of years of technological innovation and strict quality control,” said a spokesperson for Zhisheng Metal. “We are committed to solving key industry pain points such as leakage, low energy efficiency, and complex installation through patented technologies, providing global HVAC manufacturers, construction enterprises, and distributors with reliable, efficient, and safe components that drive industry upgrading.”
With 20 invention patents covering core technologies such as seamless branch pipe manufacturing and precision forming, Zhisheng Metal continues to cooperate with top domestic research institutions and universities to integrate cutting-edge academic achievements into product development. The company’s focus on technological innovation, strict quality management, and customer-centric services has solidified its position as a trusted partner in the global HVAC industry, with its high-performance branch pipes leading the way in component innovation.
