1. All seamless tubing shall be produced from type 316/L. Tubing shall be manufactured and tested to ASME SA213, ASTM A213/A269, and/or A270.
2. Seamless tubing 1/2″ and under shall be manufactured and tested to ASTM A-632.
3. All welded tubing shall be produced from type 316/L. Tubing shall be manufactured and tested to ASME SA249, ASTM A249/A269, and/or A270.
4. All 316/L material shall have a sulfur range of 0.005 to 0.012 for seamless and 0.005 to 0.017 for welded.
5. Tubing and fittings shall be seamless or welded as specified by the customer.
6. 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, BPE, SF designation (where applicable) and the heat number. Finished products shall be mill and heat traceable to the original mill test report.
7. All bar stock shall conform to the requirements of ASTM A479.

1. The ID of the tubing and fittings shall be as drawn and/or mechanically polished and electropolished to 15 uin Ra max.
2. The OD of the tubing and fittings shall be bright annealed or 32 uin Ra as specified by customer.

1. WinTech does not use mercury or ozone depleting chemicals in the process of our products.
2. After electropolishing, all material is nitric passivated and flushed clean with DI water.
3. All tubing and fittings will be cleaned per CGA G-4.1 and ASTM G93 Level A, capped, and bagged in an ISO class 5 cleanroom. Tubing is cleaned with 18 megohm-cm deionized water, heated to 140 degrees F (60 degrees C).
4. Final drying will be UHP grade nitrogen, filtered at point of use.
5. All tubing and fittings shall be individually bagged or sleeved with 4-6 mil polyethylene tubing.

1. 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. Testing may include SEM, XPS, or AES to ensure conformance to the specification.
2. WinTech will supply Material Test Reports and Certificates of Conformance with all WinTech 15 material.
