ASME AG-1a:2009 pdf download.Code on Nuclear Air and Gas Treatment.

HA.3100 GENERAL

Materials for fan components and acccssones shall be in conformance with the ASME or ASTM materials listed in

Table AA.3l00.

BA-3110 MATERIAL STRESS VALUES The ASME or ASTM designation in Table AA1 1(k) spccilics a chemical composition and a material thickness limit. A grade designation is usually required to dctermme the minimum strength 01’ the

material. If the specilk grade material has an assigned minimum yield and tensile strength. these talues shall be used for design pwjsises II values base not been established and assigned, then tests in accordance with the

proce dures outlined in ASTM A 370 and Article AA-5000 shall be performed to obtain these values. Results of mill cenilied tests performed as above designating these salues ina he used. Masimum allowable design stress values

shall he calculated by the procedures in Article AA-4fkX). These procedures require the use of an allowable stress for normal structural requirements, and correction of allowable stress for conditions where buckling can take

place and for the several service lcvels. When the minimum yield values have been established by test or by ASTM

minimums, then the allowable stress S or S,, used iii Article AA-4(k)0 shall he 64Y4 of yield.

IIA.3200 SPECIAL IIMITATIOS O% MATERIALS

Aluminum and Line shall not be used in the presence of corrosive s’apors. All materials shall be compatible with operating environmental conditions.

The ASME or ASTM material numbent and grade for the fan components selected tro,n HA-34l0 and lA-3420 shall be

identified.
