ASTM A254 Standard for Copper Brazed Steel Tubing
ASTM A254 Standard Specification for Copper-Brazed Steel Tubing. Covers double-wall, copper brazed steel tubing suitable for general engineering uses, particularly in the automotive, refrigeration, and stove industries for fuel lines, brake lines, oil lines, heating and cooling units, and the like. The tubing shall be made by rolling steel strip into the form of tubing and subsequently copper brazing in a reducing atmosphere. The steel shall conform to the prescribed chemical composition and shall be subjected to heat analysis and product analysis. Tension Tensile Strength , flattening, expansion, bending, and pressure proof tests shall be made in accordance with the specification.
This specification covers double-wall, copper-brazed steel tubing suitable for general engineering uses, particularly in the automotive, refrigeration, and stove industries for fuel lines, brake lines, oil lines, heating and cooling units, and the like. The values stated in inch-pound units are to be regarded as the standard.
