Frequently Asked Questions
What coiled tubing formats can TeCarve supply for automotive lines?
We supply seamless and welded continuous coiled tubing without joints, wrapped with protective film and packed into seaworthy wooden cases for decoiling and automotive fuel and hydraulic line fabrication.
How does TeCarve prevent cracking during tube bending and fabrication?
Tubing undergoes bright annealing to ensure ductility. Production lots receive flattening, flaring, and reverse flattening mechanical tests verifying formability under severe bending and expansion operations.
Can you provide precision cut tubes with burr-free ends for sensor housings?
Yes. We supply precision cut tubes free of burrs, prepared for automated assembly, end-forming, and sensor housing fabrication.
What are the MOQ, sample policy, and test documentation for automotive tubing?
Standard tubing orders start from 100–300 kg to assist prototype development. In-stock standard samples dispatch within 48 hours; custom samples take 5–7 working days. Every shipment includes an EN 10204 3.1 MTC.
