Custom CNC - Machined Stainless Steel Welding Tubes For Air Detection Components

Our precision-engineered stainless steel tubes are specifically designed and manufactured for integration into critical air detection systems. Through advanced CNC machining processes, we deliver custom tubular components that meet exact specifications for dimensional tolerances, surface finish, and weldability. These tubes are the essential foundation for building reliable, leak-proof, and durable air sampling, pneumatic conveyance, and sensor housing assemblies.

• Ultra-Precision CNC Machining: Each tube is machined to exacting tolerances (±0.01mm or as specified), ensuring perfect fitment and alignment within your assembly. This eliminates flow turbulence, preserves sample integrity, and prevents leaks in critical air paths.
• Superior Material Properties: Fabricated from high-grade stainless steel (304, 316, or 316L upon request), our tubes offer outstanding corrosion resistance, able to withstand moisture, aggressive chemicals, and varying environmental conditions without contaminating the air sample.
• Optimized for Welding & Fabrication: The ends and connection points are precision-machined to facilitate clean, strong, and consistent welds. This ensures structural integrity and a perfect hermetic seal, which is paramount for maintaining system pressure and preventing false readings in detection equipment.

A: Our tubes are precision CNC-machined from high-grade stainless steel (typically 316L) to hold extremely tight tolerances (±0.01mm). This ensures a perfect fit, eliminates internal turbulence that could trap samples, and provides an ideal surface for achieving a hermetic weld. The corrosion-resistant material prevents contamination of sensitive air samples, which is paramount for accurate detection and analysis.

A: We highly recommend 316L stainless steel for most air detection applications. Its superior corrosion resistance, particularly against chlorides and acids, makes it ideal for harsh environments. It also has excellent weldability and low carbon content, minimizing the risk of carbide precipitation in the heat-affected zone (HAZ), which can lead to corrosion. Grades 304 and 303 are available for less demanding applications.

A: The internal bore is meticulously reamed and polished to a standard surface finish of Ra ≤ 1.6 µm or better. This ultra-smooth finish minimizes surface area, preventing particulate adhesion and moisture retention, which ensures the sample air stream remains uncontaminated and flow characteristics are consistent and predictable.

A: We accept 2D drawings (PDF, DWG, DXF) and 3D models (STEP, IGS, SLDPRT, X_T) for quoting. Please ensure that all critical dimensions, tolerances, and material specifications are clearly indicated on your drawings.

A: Lead time depends on the order quantity and complexity. For prototype and small-batch orders, standard lead time is typically 30-45 business days after final design confirmation. For larger production runs, we will provide a specific timeline upon order confirmation.

A: We cater to both R&D and production needs. Our MOQ for custom prototypes is as low as 5000 pieces. For production runs, we offer competitive pricing scaled with volume.
