Mechanical proporties:

Flattening Test

Tubing shall withstand, without cracking, flattening under a load applied gradually at room temperature until the distance between the load platens is not more than H in. H is calculated as SB338 standard.

Flaring Test

For tube 3 1/2 in.(88mm) in outside diameter and smaller, and 0.134 in.(3.4mm) in wall thickness and thinner, a section of tube approximately 4 in.(102mm) in length shall withstand being flared with a tool having a 60°included angle until the tube at the mouth of the flare has been expanded in accordance with table4 the flared end shall show no cracking or rupture visible to the unaided eye. Flaring tests on larger diameter tube or tubing outside the range of standard shall be as agreed upon between the manufacturer and the purchaser.

Hydrostatic or Nondestructive Testing

Welded tubing shall be tested using both a nondestructive electromagnetic test and an ultrasonic test as described in standard. Seamless and welded/cold worked tubing shall be tested using an ultrasonic test as described in standard.

Welded or seamless tubing shall be tested with a hydrostatic or pneumatic test as described in standard. Other requirements details can check standard.
