Investment in increasing its stocks of stainless steel instrumentation tubes has enabled TW Metals to claim the widest range available from stock in the UK. The core of the range consists of approximately 140 items in grades AISI 304L and AISI 316L. All are fully certified to ASTM A269, dual certified to ASTM A213 but with average wall and NACE MRO175. Metric sizes are also certified to NFA 49117. All 316L items have a minimum molybdenum content of 2.5% for improved corrosion resistance.
As well as the instrumentation standard sizes, TW Metals carries a comprehensive range of complementary and non-standard sizes between 1/32â? (0.79mm) and 6â? (152mm) outside diameter in both AISI 304L and AISI 316L grades.
TW Metals offers a full range of stainless steel and nickel alloy fittings through co-operation with instrumentation tube system supplier, Parker Hannifin.
TW Metals has just issued a new 6-page technical guide on “Tubes for Instrumentation and Measurement, Hydraulics and Actuation.” It contains a full listing of available tube sizes with weights, and details physical properties, chemical analysis and bursting pressure calculations.
