General Technical Information for Exquip Protectors
Exquip Protectors are designed, manufactured and tested to match & exceed:
- API 5CT Annex F
- IADC/SPE 17209 & 11396
- Tests for special designs with up to 5000 Joules impact Resistance
Properties:
- Material: HDPP (High Density Polypropylene, Impact Copolymer)
- Diameter range: 2 3/8“ to 52“
- Temperature range: -46°C (-50°F) to 66°C (150°F)
- Threaded and Non-Threaded Designs
- Exquip Protectors are up to 70% lighter than conventional protectors
- High chemical resistance
- High strentgh elasticity and natural stability, no steel reinforcement
- UV stabilized
- Environmentally friendly due to full recycelbility
Installation & Torque
Exquip protectors are equipped with two or four torque slots at each face-end (bumper). Due to their light weight they are extremely easy to handle and can be torqued and slackened with a simple bar. The positive relaxation characteristics of the material prevents jamming of the protectors even under the heaviest impact experienced in the field.
Recommended Minimum Installation Torque Values*
| Diameter | Min. Installation Torque |
| 2 3/8“ – 3 ½“ | 80 Nm |
| 4 ½“ – 5 ½“ | 100 Nm |
| 6 5/8“ – 9 5/8“ | 130 Nm |
| 10 ¾“ – 16“ | 150 Nm |
| 18 5/8“ – 26“ | 180 Nm** |
| 26“ and above | 200 Nm +** |
*Please note that the required installation torque depends on the type of connection and expected environmental conditions during transport. These values should be understood as a rough guideline only. **Exquip strongly recommends installation with steel bar and hammer using the protectors dovetails slots for diameters of 18 5/8" or bigger (recommended field installation).
Impact Resistances for Standard Protectors
Exquip protectors are designed and manufactured to bear the following impact energy. The protector design can be modified - due to customers requirements - if more or less impact resistance is required.
