Stainless Steel Options

Stainless Steel Collection Basin:

12.1: Replace paragraph 12.1 with the following: The collection basin shall be heavy-gauge Series 300 stainless steel. Suction connections shall be equipped with stainless steel debris screens. A factory installed, float oper- ated, mechanical make-up valve shall be included. An overflow and drain connection shall be provided in each cell of the fluid cooler. The basin floor shall slope toward the drain to allow complete flush out of debris and silt which may accumulate. All steel items which project into the basin (anchor clips, etc.) shall also be made of stain- less steel.

All Stainless Fluid cooler

6.1Replace paragraph 6.1 with the fol- lowing: Except where otherwise spec- ified, all components of the fluid cooler shall be fabricated of heavy-gauge, series 300 stainless steel. The fluid cooler shall be capable of withstanding water having a chloride content (NaCl) up to 750 mg/L; a sulfate content (SO4) up to 1200 mg/L; a calcium content (CaCO3) up to 800 mg/L; silica (SiO2) up to 150 mg/L; and design operat- ing ranges up to 10°C. The circulating water shall contain no oil, grease, fatty acids, or organic solvents.

4.1Replace paragraph 4.1 with the fol- lowing: Coil(s) shall consist of fully welded box headers with serpentine coils. All coil components shall be assembled from series 300 stainless steel. Coils shall be tested to 2757 kPa air pressure while immersed in water. Maximum operating design pres- sure shall be 1551 kPa. The coil shall be designed for free drainages of fluid at shutdown.

Specification Value

■The cold water basin is the only part of the fluid cooler that is subject to periods of stagnant water, concentrated with treatment chemicals and customary contaminants. It is also the most expensive and dif- ficult part of any fluid cooler to repair or replace. For these reasons, many customers—particularly those who are replacing older fluid coolers—choose to specify stainless steel cold water basins.

■For pure resistance to corrosion—coupled with the capability to meet stringent fire and building codes—there is no substitute for stainless steel. No paints or electostatically-applied coatings, however exotic they may be, can match stainless steel's ability to withstand adverse operating conditions.

■For process fluids that are not compatible with the standard galva- nized steel construction, stainless steel offers you the ultimate in cor- rosion resistance and long life. The thermal performance rating shall be based on the Cooling Technology Institute certified performance rating adjusted for the thermal properties of stainless steel.
