Key Features of ASTM A795

erw carbon steel pipe

ASTM A795 is a very important standard in the field of steel tubing that ensures the safety and quality of steel tubing for fire sprinkler piping and a variety of industrial applications. 

Developed and maintained by the American Society for Testing and Materials (ASTM), the standard establishes specific requirements for black and hot-dipped galvanised welded and seamless steel pipe, setting the benchmark for material quality, dimensional accuracy and overall performance.

Key Features of ASTM A795:

Wide range of applications:

ASTM A795 has a wide range of applications and is the standard of choice for fire sprinkler systems and industrial piping.

In construction: piping that meets ASTM A795 plays a role in the reliable conduit of water and other fluids. It can withstand the challenges of residential construction to large facility buildings.

In the field of transport: ASTM A795 in the field of transport, where the durability of the pipeline is crucial. Whether you are transporting liquids or gases in a pipeline, the stringent requirements of the standard ensure a durability that meets the requirements of the piping system.

In the oil and gas sector: the STM A795 standard for material quality and corrosion resistance ensures that these pipelines maintain the structural integrity of the pipeline in harsh conditions such as oil and gas extraction and transport.

Grading specifications:

The standard introduces two distinct grades, Grade A and Grade B, each tailored to meet specific requirements. 

ASTM A795 Grade B, in particular, requires a post-weld heat treatment to eliminate untempered martensite, thereby enhancing the strength and durability of the pipe, a critical factor in applications where safety is paramount.

Material and Coating Requirements:

ASTM A795 specifies strict material specifications to ensure that the pipe meets the necessary strength and corrosion resistance criteria. 

Hot dip galvanising further enhances the durability of the pipe, allowing it to withstand the challenging conditions often encountered in industrial and fire fighting environments.

Hot-dip galvanising for improved longevity:

A key requirement of ASTM A795 is to perform hot dip galvanising, which is an additional layer of corrosion protection. The process involves dipping the pipe into molten zinc, creating a strong coating that acts as a barrier between the steel pipe and corrosive elements. 

The result is enhanced resistance to rust and corrosion, extending the life of the pipes and strengthening their reliability in both indoor and outdoor environments.

Dimensional tolerances:

Dimensional accuracy is the focus of ASTM A795. This standard establishes dimensional tolerances that promote uniformity and compatibility in piping installations. This is especially important in complex systems such as fire sprinkler piping, where accurate measurements are critical to achieving optimum performance.
