Reliable Connection Solution for Modern Liquid Cooling Systems

As data center and energy storage industries rapidly expand, liquid cooling technology has become the core solution to resolve high heat dissipation challenges for high-density servers and energy storage modules. Among the key connecting components, the custom extended neck liquid cooling flange plays an irreplaceable role for sealed coolant pipeline and immersion tank connections.

Our factory specializes in CNC machining of non-standard extended neck liquid cooling flanges. Different from standard ASME forged flanges, this series features an integrated long straight neck design, which is specially engineered for immersion cooling tanks, cooling manifolds and liquid cooling module interfaces. The whole part is one-piece CNC turned to guarantee excellent concentricity, smooth inner flow channel and high-precision sealing surface, effectively preventing coolant leakage under continuous operating conditions.

Core Product Features

Premium Raw Material: Available in stainless steel 304 / 316L. Materials can be customized according to customer’s coolant and working environment requirements.
High Precision Machining: Strict CNC turning process. The sealing face is finely machined to ensure stable sealing performance for long-term liquid circulation.
Custom Drawing Machining: Non-standard sizes, bolt hole quantity, neck length and outer diameter can be fully customized based on clients’ drawings. OEM & ODM services are supported.
Strict Quality Inspection: Every finished flange undergoes dimension and surface inspection before shipment. Third-party inspection including TUV, SGS, BV is acceptable. Non-destructive testing such as PT, UT and PMI can be provided upon request.
Flexible MOQ: Minimum order quantity is 1 piece. We support prototype sample production and mass batch manufacturing.

Application Scenarios

This extended neck liquid cooling flange is widely applied for:

✅ Data center server immersion cooling tank

✅ Energy storage cabinet liquid cooling manifold system

✅ High-power equipment liquid cooling module connection

✅ Semiconductor equipment cooling loop

We have over 20 years of metal forging & precision machining experience, with ISO and CE certifications. We can provide laser marking for customer logos, and offer multiple packaging options including plywood cases for safe sea or air shipment. Our lead time is normally 7–15 working days after drawing confirmation.

We export customized flanges and pipe fittings to Spain, Italy, USA, Brazil, Turkey, Southeast Asia and other regions worldwide. Our engineering team can provide technical support and design consultation for your liquid cooling projects.

Pipe fittings are crucial components in the piping system, used for connection, redirection, diversion, size change, sealing or controlling the flow of fluids. They are widely applied in fields such as construction, industry, energy and municipal services.

Key Functions: It can perform functions such as connecting pipes, changing flow direction, dividing and merging flows, adjusting pipe diameters, sealing pipes, controlling and regulating.

Application Scope:

Building water supply and drainage: PVC elbows and PPR tris are used for water pipe networks.
Industrial pipelines: Stainless steel flanges and alloy steel elbows are used to transport chemical media.
Energy transportation: High-pressure steel pipe fittings are used in oil and gas pipelines.
HVAC (Heating, Ventilation, and Air Conditioning): Copper pipe fittings are used to connect refrigerant pipelines, and flexible joints are used for vibration reduction.
Agricultural irrigation: Quick connectors facilitate the assembly and disassembly of sprinkler irrigation systems.
