Anodes

  • Sacrificial anodes for our hot water storage tanks are available rigid or flexible. They are made from magnesium alloy rod, attached to a 1.25" MPT plug. One or more anodes weighing 25g per sq ft of tank area are supplied with all Hanson glass lined tanks and are optional with cement lining. They are not offered with epoxy type linings as their action has been known to attack the bond between the epoxy and the steel, causing blisters.

  • They are to be screwed tightly into carbon steel tappings in the tank indicated on the shop drawing before a new tank is put into service. If on the top of the tank they will normally be the flexible style, made from 10" sections with stainless steel cable links. Elsewhere they will be rigid, which are much easier to install in a new tank if it is positioned so that the anode can be dropped in vertically before the tank is set. When rigid anodes are being replaced in service, the tank must be drained down to the level of the anode before it is removed. This is not necessary with top mounted anodes, but all valves must be closed and pumps switched off in both cases. Extreme care must be taken when removing anodes to avoid scalding.

  • The purpose of anodes is to divert corrosive action away from any exposed carbon steel inside the tank. This is indicated by erosion of the anode, which should be replaced when it is 50% or more eroded. When it is reduced to less than 1" in diameter, an anode has lost over 48% of its weight and should be replaced. If it is still in usable condition it can be cleaned and reinstalled. Residue in the bottom of the tank must be cleaned out. As erosion of the anodes varies from tank to tank, the inspection schedule should be adjusted to suit. A maximum one year interval is recommended. When ordering replacement anodes, please include the tank serial number which can be found on the nameplate near the manway.

  • All glass lined tanks are supplied with 25 grams of anode per sq.ft. of tank area.

  • List prices below are for replacements (all 1 1/4" dia.) plus $44 per anode for the tapping, when installed in a new cement-lined tank.

  • We do not install anodes in epoxy lined tanks, as blistering of the lining may occur.

  • Flexible anodes are available in 12" increments only. Rigid up to 66" only.

  • MINIMUM ORDER: For orders up to $500, purchasers without an open account must pay by credit card.

  • If the parts cost is less than $100, a $10 service charge will be added.

  • Packing and shipping is extra and does not count towards the above limits.
