Durammo® is MATCOR’s factory-assembled, ready-to-install deep anode system for cathodic protection of pipelines, wells, and buried infrastructure. Nearly 10,000 systems have logged over 200 million hours, featuring MMO anodes, patented Kynex® connections, and Kynar® cables.
Anode: Durammo uses a continuous MMO anode that extends the entire length of the active area, eliminating the need for adjusting resistors or a resistor junction box. Durammo’s Kynex® anode connections are designed to provide uniform current distribution and minimize IR drop.
Cables: Kynar insulated cables minimize chlorine gas degradation. The patented design of the Durammo system uses fewer cables than the old method of using individual anodes.
Kynex Connections: MATCOR’s patented Kynex anode to cable connection, made of the same material as the cable insulation, is an injection-molded encapsulation that creates an outer cable connection that is one continuous piece, providing the best protection for the anode to cable connection.
System Lowering Rope: A lowering rope is included with the Durammo anode assembly. The rope is the full length of the system and can remain in the borehole.
Bottom Weight: A bottom weight that quick-couples to the bottom assembly is included with Durammo to help lower the system and keep it centered.
SuperVent™: The MATCOR SuperVent pipe provides superior venting compared to other systems, and its fabric wrap makes it virtually immune to blockage.
System Reel and Packaging: The entire anode system, excluding the bottom weight, is delivered on a single custom reel. Once the weight is quick-coupled to the system, it is ready to install. There is no need to have a number of cable reels and anodes strung out over the ground. The system reel simply sits over the borehole. The system reel and bottom weight are on a skid or in a single container for storage and stacking. MATCOR can provide low resistance carbon backfill suitable for pumping with the system or or supply an approved alternative.
Optional Casing Kit: A Durammo Casing Kit is available to complete the installation. The kit is made of Schedule 80 PVC, and includes a support bar for the SuperVent, cables and lowering rope. A removable locking cap has a built-in vent.
MATCOR engineers can handle your complete Durammo Deep Anode System design, from data collection to complete design drawings and specifications. However, if you have deep anode system design capability, Durammo is the easiest system to design and use.
Durammo Deep Anode Systems are available in any total depth, active anode length and desired life. The Durammo Deep Anode System performs like a single long anode. Uniform current distribution is possible along the entire length of the anode due to the computer designed cable connections and jumpers. Two areas must be considered in the design: the active anode area and the inactive area. The active area is the length of the anode in the system. The inactive area is the length or depth of the system that does not produce current. The inactive area helps to gain distance from the structure and to increase current distribution. Durammo anode systems are available in almost any current output rating and life required. Systems are available up to 1,000 ft. deep with a design life in excess of 100 years.
To order the Durammo Deep Anode System:
Installation takes only minutes after the hole is drilled. The steps are simple:
MATCOR engineers and manufactures proprietary cathodic protection products in the USA, combining proven field performance with the quality systems and supply chain control that critical infrastructure demands.
Proprietary products manufactured in-house with millions of documented operating hours and reliable domestic supply chain control.
Products designed by our own corrosion engineers to solve real-world problems, not just meet spec.
