The finished Stainless Steel Liquid Cooling Tube features mirror inner and outer surfaces, ultra-tight dimensional tolerance and zero leakage airtight performance. A complete range of seamless and welded standard specifications is available, with flexible customization on tube length, wall thickness, inner surface roughness and anti-corrosion surface finish. All buyers can send inquiries for real-time quotation of Stainless Steel Liquid Cooling Tube, apply for free sample testing and obtain professional engineering matching technical plans, and we fully support large-volume international procurement and global export delivery.

Core Advantages and Selling Points

Outstanding Coolant Anti-Corrosion Performance Made of low-carbon stainless steel substrate, this Stainless Steel Liquid Cooling Tube effectively resists erosion from deionized water, ethylene glycol mixed coolant, fluorinated liquid and other heat transfer media, preventing pipeline scaling, rusting and medium leakage. It maintains stable working performance during years of cyclic fluid circulation, greatly extending the overall service life of the liquid cooling system and lowering long-term procurement replacement costs.

Uniform Stress Distribution & Wide Temperature-Pressure Adaptability The standard circular cross-section evenly disperses hydraulic impact stress with excellent burst pressure resistance. The pipe can operate stably under a working temperature range of -40℃ to 150℃, perfectly matching low, medium and partial high-pressure liquid cooling circulation working conditions for different new energy and IT cooling projects.

Superior Comprehensive Machinability for On-Site Assembly The material supports cutting, cold bending, laser welding, internal threading, flange processing and other secondary machining operations without cracking or deformation. It can be seamlessly connected with cold plates, quick connectors, manifold assemblies and cooling modules, greatly simplifying pipeline layout construction and shortening the project procurement and installation cycle.

Dual-Type Supply for Diverse Procurement Scenarios Both seamless and laser welded versions of Stainless Steel Liquid Cooling Tube are in stock to satisfy different working conditions. Seamless pipes apply to ultra-high precision chip direct cooling systems with strict leak-proof standards; welded pipes feature high production efficiency and competitive prices, ideal for large-scale bulk procurement of medium-pressure energy storage and server cluster cooling main pipelines.

Production Process and Quality Assurance

We operate fully automatic numerical control cold drawing production lines, precision laser welding equipment and multi-process strict flaw detection including helium mass spectrometer leak testing, hydrostatic pressure bursting test and metallographic microstructure inspection. The entire manufacturing process strictly complies with international precision pipe standards and holds complete ISO9001 quality management system certification. Every batch of Stainless Steel Liquid Cooling Tube can provide complete material test certificates, dimensional tolerance inspection reports, airtight leak test records and surface roughness detection documents for purchasers, realizing full life-cycle traceability and verifiable quality for all bulk procurement orders.

Frequently Asked Questions

Q1: What are the core performance differences between seamless and laser welded Stainless Steel Liquid Cooling Tube?

A: Seamless Stainless Steel Liquid Cooling Tube is integrally cold-drawn from solid stainless steel billets without any welding seam, featuring ultra-high airtightness and pressure resistance. It is suitable for high-pressure, high-precision chip direct cooling systems with strict zero-leakage standards. Laser welded Stainless Steel Liquid Cooling Tube is formed by automatic laser splicing of stainless steel strips, with high production efficiency and favorable unit price, making it the preferred choice for large-batch procurement of medium-pressure energy storage cabinet and server rack main cooling pipelines.

Q2: How to select suitable surface treatment processes for Stainless Steel Liquid Cooling Tube based on procurement environments? 

A: For conventional indoor data center closed cooling circulation, bright annealing plus passivation treatment is cost-effective and meets daily anti-rust requirements. For coastal projects with high humidity and chloride ion corrosion risks, electrolytic mirror polishing is recommended to enhance pitting corrosion resistance. For ultra-clean electronic cooling systems, ultra-fine inner surface polishing can be customized. Our technical team provides free professional process selection suggestions based on your project procurement environment and cooling medium type.

Q3: How to calculate the required quantity of Stainless Steel Liquid Cooling Tube for cooling system construction?

A: The calculation depends on the project’s cooling rack span, single-loop heat load, pipeline installation spacing and overall thermal system design parameters. Our professional technical team can provide free quantitative calculation reports and specification matching tables after receiving your engineering drawings, helping you accurately control procurement quantity and avoid overstock or insufficient supply.

Q4: Does Shunchen support deep secondary processing of Stainless Steel Liquid Cooling Tube before delivery for bulk procurement orders?

A: Yes. We build a dedicated independent secondary processing workshop equipped with CNC bending machines, automatic threading machines, flange welding equipment and precision drilling machines. We can complete pre-drilling, cold bending, internal threading, flanging and integrated manifold welding according to customer drawings, delivering finished pipe assemblies to lower the construction workload and auxiliary material procurement costs for purchasers.
