SSAW welded pipe

 

SSAW welded pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature.

These pipes mainly used in petroleum and natural gas industry to transport flammable and non-flammable liquid and steel construction.

Size range:

 

  • Out diameter: 219-3200mm

  • Wall thickness: 5-25mm

  • Length 12000mm+500mm

In addition to above specification, the pipes can be produced according to customer’s requirements.

Nearest Equivalent    : BS4360 Gr50B; BS4360 Grade50D; BS4360 Gr50DD; DIN 17100 ST52-3; ASTM A572-50;JIS G3106 SM490; JIS 3101 SS490; ABS EH36; LRS EH36

S355 – an useful structural grade steel with a minimum yield strength of 355 N/mm².

S355 being widely used in the structural engineering and important source construction industries, S355 offers high yield and tensile strength and is supplied with a    variety of treatments and test options to ensure that it is a highly usable steel in your various projects.

S355 structural grade (S) carries minimum yield strength of 355 N/mm²m, the JR designation confirms that the link for you steel has undergone longitudinal Chary V-Notch    impact testing at 27J (Joules) at room temperature. Other Charpy designations include J0, J2 and K2.

S    symbol for Structural Steel

JR    symbol 20 temperature impact test

J0    syambol 0 temperature impact test

J2    symbol -20 temperature impact test

S355JR Application

Suitable for wide variety of structural application for instance: freight cars, transmission towers, dump trucks, cranes, trailers, bull dozers,    excavators, forestry machines, railway wagons, dolphins, penstocks, pipes, highway bridges, building structures, offshore structures, shipbuilding, fans,    pumps, lifting equipments and port equipments.
