Coatings Review (continued) again as a low-cost, minimal mainte- nance system for living spaces. The

Proreco® I polyurethane coatings provide an attractive high gloss ap- pearance coupled with the long- wearing capability and flexibility to withstand structural movement, im- pact and abrasion, with extended corrosion control. The Proreco® I coating system has both U.S. Navy military specification and SOLAS approvals.

Wilson Walton International has been one of the leaders in corrosion control technology for many years.

As a result of extensive experience in the field and many years of research and development, four new innovative products have been de- veloped and recently introduced—

Aquamatic II Computerized Con- troller, Aquamatic Data Logger,

Aquamatic Preloader and Zincolite

Pit-Guard Anode.

The Aquamatic II impressed cur- rent cathodic protection system in- corporates what is said to be the industry's only computerized con- troller. Mechanical meters have been replaced by large LED digital displays. Precise circuitry allows for controller accuracy to one-thou- sandth of a volt, and all calibration and self-testing is automatically carried out every nine hours. Most importantly, the computer control- ler ensures that the hull will receive the best possible protection from corrosion.

Wilson Walton has a policy of providing free analysis of recorded log readings, as this service enables ship owners and operators to main- tain complete sets of analyzed data on file. Because the effectiveness of this analysis is solely contingent on the accuracy of these readings, an

Aquamatic Data Logger has been developed to automatically record readings. The Data Logger will print a complete set of readings twice each day, with all operational pa- rameters being indicated during each printout, and all recorded readings are automatically ana- lyzed.

The Aquamatic Pre-Loader was specifically designed to prevent over-protection of the hull, which can result in premature coating fail- ure. Depending on the manufactur- er, cathodic protection systems pro- duce a leakage current of 3 to 10 percent of rated capacity. This ex- cess current is normally permissible, except on hulls which have been painted with a sophisticated coating which has remained in excellent condition. The Pre-Loader com- pletely eliminates this problem by automatically redirecting the leak- age current back into the system, thereby lowering the operating volt- age at the anodes.

Wilson Walton International has also made great strides with zinc and aluminum sacrificial anode ap- plications. The Zincoline Pit-Guard anode is specifically designed to prevent corrosive pitting on the bot- tom shell plating in cargo tanks.

With each anode resting directly on the tank bottom, protection is pro- vided during cargo voyages when residual water settles below the oil, as well as during saltwater ballast voyages.

Grow Group, Inc. Announces

Personnel Changes • Useful for both the installer and inspector • If the gage will not fully enter the gap between the nut and body shoulder, fitting pull-up is sufficient • If the gage enters the gap, you'll know pull-up is incomplete

Effective

Metal-to- Metal • Interaction of precision parts — body, front ferrule, back ferrule and nut — produces a leak-free seal with simple 1-1/4 turn pull-up • Works on thick or thin wall tubing • Seals repeatedly under make-and-break conditions • Seals consistently over a wide range of pressures, tem- peratures and temperature cycling.

Only SWAGELOK Tube Fittings offer gageability of straight fittings, and forged shaped elbows and tees in stainless steel and steel. Gages are available for 1/8" through 1" sizes. Torque-free swaging action, effective sealing and gageability are just three of the many elements of excellence for which SWAGELOK Tube Fittings are known and respected... a tradition of Excellence.
