API Tubing Engineering Table Chart

Fluid Engineering Data | Pumps Engineering Data

API Tubing Engineering Data Chart: When placing orders for tubing to be manufactured in accordance with API Spec. 5CT, the purchaser should consult APISpec. 5CT Sec. 4. At a minimum, the following requirements should be specified on the purchase order:

  • The specification (API/ISO)
  • Quantity
  • Size designation [outside diameter (OD), normally in inches]
  • Weight designation
  • Grade and type
  • End finish (type of connection)
  • Range length
  • Seamless or electric weld
  • Delivery date
  • Shipping instructions

API tubing specifications contain several provisions that are optional for the purchaser and other stipulations that are by agreement between the purchaser and the manufacturer. Some of these added provisions may be critical to a particular application; therefore, familiarity with API/ISO tubing specifications is needed.
