ASME SA / A691 Pipe Exporter
ASME SA Pipe:
ASME: The American Society of Mechanical Engineers is a professional organization that establishes codes and standards for various engineering practices, including those related to pressure vessels, piping systems, and boilers.
SA: ASME SA stands for "ASME Standard for Pressure Vessel and Boiler Quality Steel." This specification primarily deals with the materials used in the construction of pressure vessels, boilers, and related components. It ensures that the materials used can withstand the high pressures and temperatures associated with these applications.
A691 Pipe:
ASTM A691: This specification is developed by the American Society for Testing and Materials (ASTM). ASTM is a globally recognized organization that sets standards for a wide range of materials and products, including steel pipes.
A691: ASTM A691 specifies electric-fusion-welded (EFW) steel pipes made from various grades of carbon and alloy steel. These pipes are designed for high-temperature and high-pressure applications, such as those encountered in power generation plants, refineries, and petrochemical industries.
ASME SA and ASTM A691 are both crucial in ensuring the quality and performance of steel pipes used in demanding industrial environments. ASME SA focuses on materials for pressure vessels and boilers, while ASTM A691 specifies the manufacturing standards for electric-fusion-welded steel pipes used in high-temperature and high-pressure applications. These standards help ensure the safety and reliability of industrial piping systems.

Scope
This specification covers steel pipe 16 inches in outside diameter or larger that is electric fusion welded (EFW) with filler metal added, fabricated from pressure vessel quality plate and suitable for high-pressure service at moderate temperatures. Several grades designate the type of plate used; classes designate the type of heat treatment performed during the manufacture of the pipe, whether the weld is radiographically examined, and if the pipe has been pressure tested.
Chemical composition
Product analysis of plate: The pipe manufacturer shall make an analysis of each mill heat of plate material. The product analysis shall meet the requirements of the plate specification to which the material was ordered.
Product analysis of weld: The pipe manufacturer shall make an analysis of the finished deposited weld material from each 200 feet or fraction thereof. Analysis shall conform to the welding procedure for deposited weld material.
Heat treatment
Classes 10, 11, 12 and 13 are not heat treated. All other classes must be heat treated according to the parameters shown below:

ARequires quenching and tempering. B9 CR steel is an air-hardenable steel, at times retaining austenite down to near atmospheric temperature. Good practice is to allow the steel to cool to 150° F or lower before subjecting the steel to a tempering treatment or post-weld heat treatment. |
Permissible Variations in Wall Thickness and Weight
Dictated by the requirements of the specification to which the manufacturer ordered the plate.
Permissible Variations in Outside Diameter
Based on circumferential measurement +/-0.5% of the specified outside diameter.
