ASTM A53 GR.B seamless thin-walled steel pipe

ASTM A53 GR.B seamless thin-walled steel pipe is a steel pipe produced in accordance with the American Society for Testing and Materials (ASTM) standards. It is widely used in fluid transportation systems, such as the transportation of oil, natural gas, water, and steam. This type of steel pipe is favored for its excellent mechanical properties and corrosion resistance. Here are some key information about ASTM A53 GR.B seamless steel pipe.

Chemical composition:

The chemical composition of ASTM A53 GR.B steel pipe includes carbon (≤0.30%), manganese (0.29~1.06%), phosphorus (≤0.035%), sulfur (≤0.035%), silicon (≥0.10%), chromium (≤0.40%), nickel (≤0.40%), copper (≤0.40%), molybdenum (≤0.15%), vanadium (≤0.08%).

Mechanical properties:

The steel pipe has mechanical properties of tensile strength ≥415MPa and yield strength 240MPa.

Product specifications:

Outer diameter range from 21.3mm to 762mm, wall thickness from 2.0mm to 140mm.

Production method:

ASTM A53 GR.B steel pipes can be produced by hot rolling, cold drawing, hot expansion, etc., and can be delivered in a hot-rolled or heat-treated state.

Application areas:

In addition to use in fluid transportation systems, ASTM A53 GR.B steel pipes are also suitable for chemical, electric power, construction and other industries.

Purchase and maintenance:

When purchasing, you should choose products produced by regular manufacturers and check the specifications, dimensions, wall thickness and surface quality. During use, regular inspection and maintenance should be carried out to keep the pipes clean and dry to avoid collision damage, and damaged steel pipes should be replaced or repaired in a timely manner.

ASTM A53/A53M standard:

ASTM A53 GR.B steel pipe complies with ASTM A53/A53M-2020 standard, covering the technical requirements of uncoated and hot-dip, galvanized, welded and seamless steel pipes.
