High-precision tubes Smal l diameter PTFE coated nitinol tube for PTCA guide wires, catheters and needles

Precision welded steel tubes Tubos de Precisión Delmas SL is a manufacturer of precision welded steel tubes of very small diameters. The company’s technology allows it to adapt production to customers’ requirements, such as tight diameter tolerances, tubes cut in fixed lengths, and deburred and annealed tubes with very bright surface. Delmas offers a precise outside calibrated tube and a precise outside and inside calibrated tube. Products range from 3 to 15mm OD and from 0.5 to 2mm wall-thickness. Tight tolerance parts from China Tubetech, China, is an ISO certified supplier of small diameter metal tubular products. The company’s focus is on fabricating small diameter, tight tolerance metal tubular parts to exact customer specifications. The company provides a combination of desired characteristics: dimensional accuracy, clean and smooth surface quality, high corrosion and heat resistance, and good machinability. The main production techniques include argon welding and cold drawing, using TP 304/304L, 321 and 316/316L. Outside diameter range is 0.1 to 10mm, wall thickness range is 0.03 to 1mm, and lengths start from 0.5mm. Tubetech’s standard tolerance for cutting is ±0.5mm, but the company can meet required precisions as tight as ±0.02mm.
