ASTM A790 Seamless Pipes are high-performance duplex and super duplex stainless steel pipes which are designed to be used in situations where the combination of high mechanical strength, excellent corrosion resistance and long-term operational reliability is necessary. These pipes are fabricated with perfect seamless production methods so that they have homogenous grain construction, uniform wall thickness, and high resistance to internal pressure and mechanical stress.
ASTM A790 Seamless Pipes has various applications in the oil and gas industry, offshore exploratory, chemical processing, desalination facilities, and marine engineering, which require continuous exposure to the hostile chemicals, chlorides, and extreme environments. The duplex microstructure of these pipes gives an optimum mixture of austenitic and ferritic properties which give high resistance to stress corrosion cracking and also excellent toughness and weldability.

Understanding ASTM A790 Seamless Pipe Specification
ASTM A790 is a standard specification that is related to seamless and straight-seam welded ferritic/austenitic stainless steel pipes, which are also known as duplex stainless steel pipes. The specification is mainly aimed at the pipes used in corrosive services with special focus on the ability to resist the chloride induced stress corrosion cracking, a usual mode of failure in traditional stainless steels.
Continuous pipes made of ASTM A790 are more desirable in demanding systems since they avoid the dangers of welded interconnections like welding flaws or disparity in mechanical integration. This renders them very adapted in environments with high pressure, high temperature and chemically hostile whereby integrity and safety of the system cannot be compromised.
ASTM A790 Seamless Pipe Grades and Material Classification
The available grades of ASTM A790 Seamless Pipes are numerous duplex and super duplex stainless steel grades, each having been determined through the degree of corrosion exposure and mechanical performance requirements.
|
ASTM A790 Grade |
UNS Number |
Stainless Steel Type |
|
ASTM A790 Duplex |
UNS S31803 / S32205 |
Duplex Stainless Steel |
|
ASTM A790 Super Duplex |
UNS S32750 |
Super Duplex Stainless Steel |
|
ASTM A790 Super Duplex |
UNS S32760 |
Super Duplex Stainless Steel |
These grades provide successively higher corrosion resistance and strength levels, and are appropriate both in moderate service and in extremely aggressive service.
Key Characteristics and Performance Advantages
ASTM A790 Seamless Pipes present a variety of performance advantages which gives them the edge over the competition when used by engineers and procurement managers in corrosive and high stress environments:
- Unparalleled resistance to pitting, crevice corrosion and chloride stress corrosion cracking, even in salty environments.
- Thickness of the wall can be lower since high yield and tensile strength is about twice that of normal austenitic stainless steels.
- Continuous build which guarantees that there are no mechanical property variations and that pressure handling capacity is improved.
- High fatigue strength and stability during cyclic loading
- Long life cycle, which translates to low maintenance and high lifecycle value.
