Brazing, Silver For Small Pressurized Fittings
Description / Abstract:
Purpose
This specification covers requirements for producing brazed joints in parts fabricated from corrosion and heat resistant steels, carbon or low-alloy steels, or copper alloys, and the properties of such joints.
Application
This process has been used typically for producing joints brazed between flexible metal hose, pressure fillings, pipe and tube joints, and similar parts, such as bellows and rigid end fittings where one end of the joint is not accessible for inspection, but usage is not limited to such applications.
Classification
The brazing procedure is classified by the maximum service temperature as follows:
Type 1 600 °F (316 °C) service temperature
Type 2 400 °F (204 °C) service temperature
Type 3 800 °F (427 °C) service temperature
If a type is not specified, Type 1 shall be supplied.
Maximum operating pressures will vary with part geometry and should be specified by purchaser.
Safety - Hazardous Materials
While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
Warning
Numerous scientific studies have determined that cadmium, which is used in some brazing alloys, presents a health hazard to persons who are exposed to it.
