According to API 936, ceramic fiber batten strips are used in fiber lining applications to secure joints or protect against gas penetration. The specification sets a strict requirement on their length:
"Ceramic fiber batten strips shall be a maximum length of 3 ft (0.9 m)."
- API Std 936, Section 5.3.2.3
Other anchoring methods such as lock studs or staples may apply in different contexts or materials, but they are not prescribed for ceramic fiber batten strips per this specific requirement.
