Why Us?
Customer benefits | Implementation Path | Data comparison |
Reduce purchasing cost by 30% | Bulk packaging purchase (pipe + Screw + surface treatment combination discount) | Savings in Logistics/management costs compared to decentralized purchasing |
Lead time reduced by 50% | Stock sharing (200 tons safety stock of common materials) | Urgent order, 72 hours, rush delivery |
Zero risk to quality | Material consistency guarantee (the same batch of bar processing pipe + Screw) | Assembly failure rate reduced from 5 per cent to 0.3 per cent |
Material Matrix
Type | Is for material | Capacity under extreme operating conditions |
High temperature resistant tube | GH4145 | Continuous temperature resistance 750 °C/burst pressure 50 mpa |
Corrosion resistant pipe | Inconel 625 | Resistance to 98% sulfuric acid/seawater flow rate of 5 m/s |
Low expansion pipe; low expansion pipe | 4J29 | Expansion coefficient ≤1.8 × 10-6/°C (20-400 °C) |
Processing capacity:
– thin-walled tube: 0.1 mm wall thickness (for nuclear magnetic resonance helium cycle lines)
– shaped tube: square tube/bellows/capillary one-piece molding
Guaranteed Performance
Material： Kovar alloy (4J29/4J36/4J42) , oxygen-free copper (OFHC C10100) , pure Nickel (Nickel 201)
Technical parameters：Inner diameter
Accuracy： ± 0.01 mm (customizable φ0.1-5 mm)
Special Process： vacuum annealing (ensure 4J29 sealed with glass with zero leakage)
Category：
– tape: thickness 0.05-3 mm (1J22 soft magnetic tape for transformer cores)
