   en.wikipedia.org/wiki/Prestressed_concrete...

   Prestressed concrete cylinder pipe (PCCP) is a common variety of large-diameter concrete pressure pipe used for transporting water and wastewater.PCCP is typical manufactured according to the American Water Works Association (AWWA) standard C304. [1]

3. Flow table test - Wikipedia

   en.wikipedia.org/wiki/Flow_table_test

   Flow table with a grip and a hinge, 70 centimetres (28 in) square. In the American version of this test, the table is 10 inches (25 cm) diameter per ASTM C 230.; Abrams cone, open at the top and at the bottom - 30 centimetres (12 in) high, 17 centimetres (6.7 in) top diameter, 25 centimetres (9.8 in) base diameter.

   In sizes of up to 6 m (20 ft) diameter and 15 m (49 ft) length. With a wall thickness range from 2.5 to 125 mm (0.098 to 4.921 in). In tolerance limits of the outer diameter of 2.5 mm (0.098 in) an die inner diameter of 3.8 mm (0.15 in). In a surface finish from 2.5 to 12.5 mm (0.098 to 0.492 in) rms.

5. Pipe (fluid conveyance) - Wikipedia

   en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

   Since the outside diameter is fixed for a given pipe size, the inside diameter will vary depending on the wall thickness of the pipe. For example, 2" Schedule 80 pipe has thicker walls and therefore a smaller inside diameter than 2" Schedule 40 pipe. Steel pipe has been produced for about 150 years.

6. Hollow structural section - Wikipedia

   During the manufacturing process the mother tube goes through a series of shaping stands which form the round HSS (mother tube) into the final square or rectangular shape. Most American manufacturers adhere to the ASTM A500 or newly adopted ASTM A1085 standards, while Canadian manufacturers follow both ASTM A500 and CSA G40.21.
