General Technical Information for Exquip Protectors

Exquip Protectors are designed, manufactured and tested to match & exceed:

  • API 5 CT Annex I
  • 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.
