ASTM A928 pipe

ASTM A928 pipe

Piping that adheres to the specifications laid down by ASTM or the American Society for Testing and Materials delivers dependable and consistent performance. ASTM A928 caters to duplex grades that have both ferritic and austenitic structures. The standard encompasses stainless steel pipe produced by electric fusion welding and filler metal for corrosive resistance. It also lists the heat treatments for an ASTM A928 pipe.
An integral part of the specification is the set of tests for quality assurance. For instance, the piping undergoes a transverse tension and a nondestructive test. It also goes through hydrostatic testing.

You can get A928 piping in different schedules depending on the requirement. The SCH indicates the nominal wall thickness for ASTM A928 efw pipes. SCH40 refers to schedule 40 and is the most commonly employed pipe schedule. Here, the 40S refers to a stainless steel designation. It varies for different types of steel based on the specification, for example, ASME B36.10 or ASME B36.19. It is a robust and versatile component employed in high-performance environments. Water and gas pipes often use this schedule.
SCH 10 signifies schedule 10. An ASTM A928 cl1 pipe from this schedule will be able to handle lower pressure. The exact dimensions, like diameter and wall thickness, will differ based on your chosen standards.

This standard groups piping into five classes based on the welding technique and radiography requirements. In Class 1, the pipes get double-welded with a filler metal. ASTM A928 class 1 pipe must get radiographed.
Class 2 also requires double-welding with filler. But radiography is not essential.
Class 3 and Class 4 are similar. They both specify single-welded pipes. The former must use filler for all the passes. In contrast, Class 4 allows the weld pass in contact with the inner surface without filler.
Lastly, Class 5 requires double-welding with filler. The piping also has to get spot radiography.

It is another name for the A928 standard. The ASTM A928m specification covers many grades of ferritic and austenitic steel. All the salient areas get covered – heat treatment, tensile strength properties, and grade-related requirements.
The specification details the classes, the required tests for the piping, and the required heat treatment. You can use an ASTM A928m stainless steel pipe for your requirements to ascertain its performance in different environments.
You can check the additional requirements to ask for more provisions, like an extra test or a specific manufacturing practice. The ASTM standard numbers these from S1 to S4.

When you choose pipes conforming to this standard, you get guaranteed quality. A928 material undergoes tests like a transverse tension test and hydrostatic testing to detect any imperfections. Using compliant materials is an effective way to achieve compatibility across brands and avoid problems in quality.
An A928 pipe is resistant to corrosion cracking and stress-induced damage. It also has good tensile strength and magnetic properties. The weldability is satisfactory, although lower than fully austenitic grades. Low thermal expansion is an attractive trait to limit distortion. It also tackles residual stresses after welding.

The applications of this material include chemical processing, marine industries, and refineries for oil and gas. Pollution control and paper manufacturing rely on SA928 components, as do construction, water treatment, transport, and desalination units.
The chemical and metallurgical properties of an SA928 pipe lend it utility in heat exchangers, pressure vessels, and pipelines. The scrubber apparatus and hulls of ships use A928 material as well.
Users can select piping of the appropriate class from 1 to 5, depending on welding needs and radiography requirements. Thoroughly tested and appropriately heat-treated material will help you get optimal results in your application.
