Tapered End External Bolted Segmented Bracelet Aluminum Anode
Indium-activated segmented bracelet anode for pipeline cathodic protection, easy installation with clamps.
Description
Our indium-activated segmented bracelet aluminum anode is tailor-made for safeguarding submarine/offshore pipelines. Comprising multiple individual anode sections, this segmented bracelet is ideal for direct attachment around pipeline circumferences, installed using clamps. Featuring tapered ends, it facilitates smooth movement over stringers during pipeline laying.
Quality Substrate Material
Our bracelet anode, made from high-purity alloys with low iron content, conforms to ISO, NACE, and DNV standards.
