Marking:  Bright annealed tubing is line-stenciled with OD, wall, ASTM specification, manufacturer, grade, heat number, or per ASME-BPE.

Mechanical Tests:  To ensure the highest quality in all of our sanitary products, WinTech meets or exceeds the requirements of ASTM and/or ASME A213 EAW, A269 and/or A270 S2, per order. 

Surface Finish:  All ID surface finishes are u-in Ra maximum, with an optional 32 u-in OD maximum measured per ASME/ANSI B46.1.

Cleaning:  As an option any WinTech product can be TC&C (thermocouple cleaned and capped) or CFOS (cleaned for oxygen service).  Class 10 cleanroom processing and packaging is available for final cleaning.

Inspection:  100% of all WinTech tubing shall be inspected for conformance to most recent ASME BPE or SEMI acceptance criteria for interior surface finishes of tubing.

Winter Technologies will supply the following reports and certificates of analysis with all

WinTech orders when applicable:

•           Material Test Reports
