Capillary Tubes constitute one of the most very important elements of the fluid transfer, as well as instrumentation systems that require accuracy and precision in the processes. Hindco Steel And Alloys is one of the leading Suppliers Manufacturers of very good quality high Capillary Tubes to applied international specifications, i.e. ASTM A213 TP316L and UNS S31603.

These tubes are carefully stipulated and designed using high quality stainless steel to guarantee optimum performance, corrosion resistance, and long life time in severe applications. Our stainless steel Capillary Tubes exceed other tubing products by being carefully drawn to a smooth inner surface and uniform diameter because of such a drawing, there is better control of the flow within sensitive measurement equipment, medical devices, thermocouples, and analytical instruments.
The scope of Boiler/Steam Tubes Capillary Tubes supplied by us at Hindco Steel And Alloys adheres to the international standard ASTM A213, an outline of the seamless tubes of ferritic and austenitic alloy-steel of boiler, superheater and heat-exchanger services. The grade TP316L, with UNS number S31603, belongs to the austenitic stainless steel grades that have a great corrosion resistance, especially in chloride environment, due to the extremely low carbon level. This gives it a perfect selection in industries like petrochemical, marine, pharmaceuticals, and food processing industry which requires high purity and chemical resistance.
Hindco Steel And Alloys takes care to perform stringent quality control on every Capillary Tube, in terms of dimensional measurement, surface finish testing as well as hydrostatic pressure testing of the same. We have an adequate manufacturing resource that can manufacture capillary tubes of different sizes, different wall thickness and lengths as per the requirement of the client. These tube can be purchased in coiled and straight, and have an outer diameter of 0.3 mm to 4.0 mm and as thin as 0.1 mm. The continuously interchanging surface reduces the friction of a fluid passing over its surface and surpasses properties of flow, which plays an important role in instrument system high-according precision.
