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 gaining prominent recognition in the global market with its cutting-edge seamless copper branch pipes. As the core component of HVAC refrigerant transmission systems, these branch pipes—also known as refrigerant distribution pipes—are pivotal to the efficiency, energy consumption, and operational stability of VRF (Variable Refrigerant Flow) systems, household split air conditioners, and commercial/industrial central air conditioning units. Amid the global shift toward energy efficiency and environmental sustainability, Xinxiang Zhisheng’s seamless branch pipes stand out as a game-changing solution, perfectly adapting to the evolving demands of R410A and R32 refrigerants and setting new benchmarks for quality and reliability in the industry.
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. Backed by a 50,000-square-meter modern production base and a team of 170 professional and technical talents, the company has established itself as a trusted partner for HVAC manufacturers worldwide, with its branch pipes becoming the preferred choice for major international brands including Mitsubishi, Daikin, Hitachi, Gree, Hisense, Samsung, Panasonic, LG, and Haier. The company’s core mission is to deliver high-reliability, energy-efficient, and technologically advanced copper branch pipes that meet the upgrading needs of commercial, industrial, and residential HVAC sectors.
Against the backdrop of increasingly stringent energy conservation policies and the global push toward carbon neutrality, R410A and R32 have become the two most in-demand refrigerants for branch pipes, especially in VRF systems and household split air conditioners. Notably, R32 is rapidly replacing R410A as the first choice in the new installation market, driven by strong policy support in key regions such as China, Japan, India, and Europe. With a global warming potential (GWP) of approximately 675—only one-third of R410A’s 2088—R32 is more aligned with international carbon reduction goals and environmental regulations like the Kigali Amendment. Xinxiang Zhisheng has proactively adapted to this trend, developing high-performance branch pipes fully compatible with both refrigerants, providing customers with future-proof solutions and a seamless transition.
The company’s seamless branch pipes are distinguished by innovative technology, superior materials, and meticulous craftsmanship. Manufactured using high-grade C12200 (TP2) deoxidized phosphorus copper and C11000 red copper, these pipes boast a copper purity of ≥99.95% and a thermal conductivity of ≥401 W/(m·K), ensuring excellent heat transfer efficiency and corrosion resistance. What sets them apart is the seamless forming technology, which completely eliminates welding points— a common weak spot in traditional welded branch pipes that often leads to leakage and corrosion. This technology not only ensures long-term reliability but also creates an ultra-smooth inner wall, reducing refrigerant friction loss by 15% and significantly improving HVAC system efficiency and energy savings, especially for R32 systems.
Pressure resistance is a core advantage of Xinxiang Zhisheng’s branch pipes, a critical requirement for safe operation with R410A and R32 refrigerants. Industry standards mandate that branch pipes for these refrigerants must pass a high-pressure test of at least 4.15MPa, but Xinxiang Zhisheng’s seamless branch pipes far exceed this requirement, easily withstanding pressures ranging from 10MPa to 18MPa. Each pipe undergoes a rigorous 16MPa pressure test during production, with an ultimate pressure resistance of 25MPa—capable of holding pressure for 30 minutes without leakage or rupture. For R32 systems, which require higher safety standards due to the refrigerant’s A2L mildly flammable classification, all necessary welding points undergo 100% helium inspection, detecting micro-leaks as small as 1×10^-9 mbar·L/s to ensure absolute safety.
To ensure uncompromising quality, Xinxiang Zhisheng adheres to the highest international standards, holding ISO 9001:2015 quality management system certification. The company has established a full-process quality control system from raw material procurement to finished product delivery, equipped with advanced testing equipment such as spectral analyzers, pressure testing machines, and environmental test chambers. All raw materials meet international standards including ASTM B280, EN 1254, and GB/T 19228, with complete material certificates for full traceability. Additionally, the branch pipes comply with EU RoHS 2011/65/EU and REACH (1907/2006/EC) regulations, free from restricted substances and tested for 234 high-concern substances, ensuring environmental safety for global markets.
Technological innovation is the driving force behind Xinxiang Zhisheng’s success, with the company holding 20 invention patents covering core technologies such as seamless branch pipe manufacturing, reducing three-bend shaping and clamping mechanisms, and claw-type three-way stamping devices. These patents address key industry pain points including leakage, low energy efficiency, and complex installation. The patented seamless branch pipe technology, in particular, not only prevents leakage but also optimizes refrigerant flow, while the Y-type three-way stamping technology reduces turbulence and pressure loss, ensuring uniform refrigerant distribution in VRF systems. The company also collaborates with top domestic research institutions to develop innovative products like intelligent electronic expansion valve (EEV) branch pipes, which feature real-time flow control with ±5% accuracy and Modbus communication to further enhance energy efficiency.
Xinxiang Zhisheng offers a comprehensive range of branch pipe solutions, including seamless branch pipes, Y-type, T-type, and reducing branch pipes, as well as brand-specific options tailored for Daikin, Mitsubishi, and other leading HVAC brands. These brand-specific branch pipes are engineered to meet the exact specifications of each brand’s VRF systems, ensuring seamless integration and optimal performance. The company’s flexible OEM/ODM customization service further caters to personalized needs, including size, material, refrigerant compatibility, brand-specific structures, and private label customization, with a streamlined process from demand docking to mass production.
With a monthly production capacity of 500,000 standard components, Xinxiang Zhisheng’s production base features automated production lines and advanced processes such as seamless forming, precision CNC machining, and automatic assembly, ensuring high efficiency and consistent quality. The company offers flexible minimum order quantities (MOQ)—1,000 units for standard branch pipes and negotiable MOQ for customized products—along with small-batch trial orders to facilitate customer testing. Supported by international first-class logistics partners, the company delivers standard products in 15–25 working days and customized products in 15–30 working days, with air, sea, and land transportation options to over 60 countries and regions worldwide.
Customer-centric service is a core value of Xinxiang Zhisheng, with a pre-sales team of HVAC technical experts providing professional consultation, detailed product information, and technical support. The company offers up to 10 free samples for standard products (customers bear shipping costs) and deducts customized sample fees from mass orders, with a sample delivery time of approximately 7 working days. Post-sales support includes installation guidance, troubleshooting, and maintenance suggestions, with a strict quality guarantee policy to ensure customer satisfaction.
