Xinxiang Zhisheng Leads the Global HVAC Industry with High-Precision Copper Branch Pipes
XINXIANG, CHINA – April 7, 2026 – Xinxiang Zhisheng Metal Products Co., Ltd., a globally leading professional manufacturer of high-precision copper components for heating, ventilation, and air conditioning (HVAC) systems, is making remarkable strides in the global market with its cutting-edge copper branch pipes, catering to the evolving needs of VRF (Variable Refrigerant Flow) systems and household split air conditioners worldwide.
Founded in 2012 and headquartered in Xinxiang City, Henan Province, China, Xinxiang Zhisheng 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. With a core mission to provide high-reliability, energy-efficient, and technologically advanced copper components for the global HVAC industry, the company has focused on innovating copper branch pipes, a critical component that serves as the "blood vessel" of HVAC refrigerant transmission systems, directly affecting system efficiency, energy consumption, and operational stability.
As the demand for environmentally friendly and high-efficiency HVAC systems surges globally, R410A and R32 have become the two most in-demand refrigerants for branch pipes, particularly in VRF systems and household split air conditioners. Notably, R32 is rapidly replacing R410A as the preferred choice in the new installation market, driven by strong promotion in China, Japan, India, and Europe. Xinxiang Zhisheng has proactively adapted to this market trend, developing high-performance branch pipes that excel in both refrigerant compatibility and pressure resistance – a key requirement for modern HVAC systems.
The company’s seamless branch pipes stand out with their innovative technology and superior performance. Manufactured using C12200 (TP2) deoxidized phosphorus copper and C11000 red copper with a copper purity of ≥99.95% and a thermal conductivity of ≥401 W/(m·K), these branch pipes boast excellent corrosion resistance and mechanical properties. The seamless forming technology eliminates welding points, fundamentally avoiding leakage and corrosion risks, while the ultra-smooth inner wall reduces refrigerant friction loss by 15%, significantly improving HVAC system efficiency and reducing energy consumption.
Pressure resistance is a core advantage of Xinxiang Zhisheng’s branch pipes. As R410A and R32 refrigerants require branch pipes to pass high-pressure tests of at least 4.15MPa, the company’s seamless branch pipes can easily withstand 10MPa to 18MPa, far exceeding industry standards. Each branch pipe undergoes a rigorous 16MPa pressure test, with an ultimate pressure resistance of 25MPa (holding pressure for 30 minutes without leakage or rupture), ensuring stable operation even under harsh working conditions such as high pressure, high temperature, and corrosion. For R32 refrigerant systems, all welding points undergo 100% helium inspection to ensure the safe operation of A2L refrigerants.
To meet the diverse needs of global customers, Xinxiang Zhisheng offers tailored branch pipe solutions, including brand-specific products such as Daikin Branch Pipes and Mitsubishi Branch Pipes – specially designed and adapted for VRF systems of leading international HVAC brands. These brand-specific branch pipes achieve seamless integration with Daikin, Mitsubishi, Hitachi, Gree, Hisense, Samsung, Panasonic, LG, Haier, and other mainstream brands, delivering optimal system performance.
Backed by 20 invention patents, including core technologies for seamless branch pipe manufacturing, the company’s R&D team is committed to breaking technical bottlenecks in the industry. The patented reducing three-bend shaping and clamping mechanism ensures precise dimension control and uniform wall thickness, enhancing the structural strength and service life of branch pipes. Additionally, the company collaborates with top domestic research institutions and universities to integrate cutting-edge academic achievements into product development, keeping pace with market trends such as intelligent electronic expansion valve components and noise reduction designs.
Quality control is a cornerstone of Xinxiang Zhisheng’s operations. The company has obtained ISO 9001:2015 quality management system certification, establishing a full-process quality control system from raw material procurement to finished product delivery. All branch pipes comply with international standards such as ASME, JIS, ASTM B280, EN 1254, and GB/T 19228, and have passed EU RoHS 2011/65/EU and REACH 1907/2006/EC certifications, with 234 high-concern substances tested to ensure environmental and user safety.
With flexible OEM/ODM customization capabilities, Xinxiang Zhisheng can develop branch pipes according to customer drawings, technical parameters, or samples, covering personalized needs such as size, material, refrigerant adaptation, and private label customization. The company supports flexible minimum order quantities (MOQ) – 1,000 pieces for standard branch pipes and negotiable MOQ for customized products – and offers sample services to facilitate customer verification.
With an annual production capacity of 500,000 standard components per month and a global logistics network, Xinxiang Zhisheng delivers its high-precision branch pipes to more than 60 countries and regions across North America, Europe, Asia, Australia, and South America. The company’s multilingual sales team and professional after-sales support ensure efficient communication and timely service for global customers.
"As the global HVAC industry shifts toward energy efficiency and environmental protection, high-quality copper branch pipes play an increasingly critical role," said a spokesperson for Xinxiang Zhisheng. "We are committed to continuous innovation, adhering to strict quality standards, and providing customized solutions to help global customers achieve more efficient, safe, and reliable HVAC operations. Our seamless branch pipes, with their superior pressure resistance, refrigerant compatibility, and brand adaptability, are poised to lead the global market transformation."
Xinxiang Zhisheng’s commitment to technological innovation, product quality, and customer-centric service has established it as a trusted partner for global HVAC manufacturers, construction enterprises, engineering companies, and distributors, solidifying its position as a leader in the global high-precision copper HVAC component industry.
