- All seamless tubing shall be produced from type 316/L or 304/L, based on customer requirements. Tubing shall be manufactured and tested to ASTM A213/A269 and ASME SA213. Other alloys are available upon request.
- All welded tubing shall be produced from type 316/L or 304/L. Tubing shall be manufactured and tested to ASTM A249/A269 and ASME SA249.
- Tubing and fittings shall be seamless or welded as specified by the customer.
- Tubing and fittings shall be marked by an approved method per ASTM A1016 specification. The mark can contain; manufacturer’s identification, the size and wall thickness, the alloy, and the heat number. Finished products shall be mill and heat traceable to the original mill test report.
- All bar stock shall conform to the requirements of ASTM A479.
- The ID and OD of the tubing shall be mill finish.
- ID and/or OD polishing is available upon request.
- WinTech does not use mercury or ozone depleting chemicals in the process of our products.
- Cleaning and packaging options are available upon request.
- WinTech will measure tubing and fittings with calipers, micrometers, or other acceptable methods, to certify that the finished products conform to the dimensional requirements to which they were ordered.
- WinTech will supply Material Test Reports with all WinTech for-VAC.
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.
Protective Packaging
Packaging is provided to protect the OD, for polished material, as well as the ID of the products. Protective caps and bagging is available to ensure the products arrive at your site in the same excellent condition they left our facility. For WinTech 10 Polyamide Nylon film is covered then capped.
Tubing can be ordered with ends faced ready for orbital welding.
Winter Technologies will supply the following reports and certificates of analysis with all WinTech orders when applicable:
-
Material Test Reports
-
Certificate of Conformance
-
SEM, ESCA, AUGER when required
