ASME B31.5:2016 pdf download.Refrigeration Piping and Heat Transfer Components.

reinforcement of weld: weld metal in excess of the specified weld size.

root opening: the separation between the members to be joined, at the root of the joint.

root penetration: the depth a groove weld extends into the root of a joint measured on the centerline of the root cross section.

seal weld: any weld used primarily to provide a specific degree of tightness against leakage.

secondary coolant: any liquid used for the transmission of heat without a change in its state.

self-contained system: a complete factory-made and factory-tested system in a suitable frame or enclosure that is fabricated and

shipped in one or more sections and in which no refrigerant-containing parts are connected in the field other than by companion

flanges or block valves.

semiautomatic arc welding: arc welding with equipment that controls only the filler metal feed. The advance of the welding is

manually controlled.

shall: where “shall” or “shall not” is used for a provision specified, that provision is intended to be a Code requirement.

shielded metal-arc welding (SMAW): an arc welding process wherein coalescence is produced by heating with an electric arc between a covered metal electrode and the work. Shielding is obtained from decomposition of the electrode covering. Pressure is not used, and filler metal is obtained from the electrode.

should: “should” or “it is recommended” is used to indicate provisions that are not mandatory hut recommended good practice.

size of weld

equal leg fillet weld: the leg lengths of the largest isosceles right triangle that can be inscribed within the fillet weld

cross-section.

groove weld: the joint penetration (depth of chamfering plus the root penetration when specified). The size of the groove weld and its effective throat are one and the same.
