Standard Specification for Wrought Carbon Steel Sleeve-Type Pipe Couplings

ABSTRACT
This specification covers wrought carbon steel sleeve type pipe couplings suitable for joining carbon steel pipes. Couplings are furnished in two types as follows: Type I couplings are intended for use on all schedules of pipe in which the pipe wall thickness does not exceed the wall thickness of standard weight pipe. Type II couplings are intended for use on all schedules of pipe in which the pipe wall thickness does not exceed the wall thickness of extra strong pipe. The couplings shall be manufactured from material having a chemical composition conforming to the requirements specified. Couplings made from plate or tubular products need not to be heat treated. Hot-formed couplings finished at a temperature in excess of a certain value shall subsequently be annealed, normalized, or normalized and tempered. Cold-formed couplings upon which the final forming operation is completed at a temperature below a certain quantity shall be normalized or shall be stress-relieved. Carbon steel couplings made from forgings shall subsequently be annealed, normalized, or normalized and tempered. Mechanical properties of steel such as tensile strength, yield strength, yield point, and elongation shall be determined.

Overview

ASTM F682-82a(2023) is the standard specification for wrought carbon steel sleeve-type pipe couplings designed for joining carbon steel pipes. Developed by ASTM International, this specification covers two key coupling types, each suited to different pipe wall thicknesses, ensuring robust, reliable connections in piping systems. It provides requirements for material composition, mechanical properties, dimensional tolerances, manufacture, heat treatment, and marking. The standard is widely referenced in shipbuilding, industrial, and mechanical piping applications.

Key Topics

• Types of Couplings:

  • Type I Couplings: Intended for use with all schedules of carbon steel pipe where the wall thickness does not exceed that of standard weight pipe.
  • Type II Couplings: Suitable for schedules where the pipe wall thickness does not exceed that of extra strong pipe, offering a solution for more demanding applications.

• Material Requirements:

  • Couplings must be made from carbon steel conforming to specific chemical composition limits for carbon, manganese, phosphorus, and sulfur.
  • Various forms of raw stock are permissible, such as plate, tubular products, or forgings, provided all requirements are met.

• Heat Treatment and Manufacturing:

  • Specifies manufacturing options including use of plate, tubular, or forged stock.
  • Different heat treatment processes apply depending on the forming method: annealing, normalizing, tempering, or stress-relief.
  • Welded couplings require welders and procedures qualified under ASME codes and may mandate postweld heat treatment.

• Mechanical Properties:

  • Defined requirements for tensile strength, yield point, and elongation, ensuring durability and performance in service.

• Dimensional and Quality Control:

  • Prescribes nominal dimensions and tolerances for both coupling types.
  • Emphasizes workmanship, finish, and marking for traceability in industrial practice.

Applications

ASTM F682-82a(2023) sleeve-type pipe couplings provide essential solutions for secure joining of carbon steel pipes in a wide range of industries:

• Shipbuilding and Marine Engineering:
  Frequently referenced by the U.S. Department of Defense and U.S. Coast Guard regulations, these couplings are suited for marine and shipboard piping systems where reliable mechanical connections are critical.

• Industrial Piping Systems:
  Utilized in process and utility pipelines within facilities such as refineries, chemical plants, and power generation stations.

• Pressure Vessels and Boiler Applications:
  Compatible with ASME Section VIII and IX requirements, supporting high-pressure and high-temperature service.

• Infrastructure Projects:
  Relevant for municipal water, wastewater, and general pipeline construction where carbon steel pipe systems are specified.

The standard ensures compatibility, interchangability, and performance for both new installations and maintenance operations.
