PRODUCTION WELL KILL CALCULATIONS AND PROCEDURE1. DETERMINE THE DIAMETER OF THE WELL.2. DETERMINE THE “SHUT IN” PRESSURE OF THE WELL EITHER IN PSI OR FEET OF HEAD.3. CALCULATE THE FORCE ON THE WELLHEAD.a. INSIDE DIAMETER OF WELL CASING DIVIDED BY 2. (16” HOLE = 8)b. SQUARE THAT NUMBER. (8X8 = 64)c. MULTIPLY BY 3.14 (64 X 3.14 = 200.96)d. THE RESULT IS THE TOTAL SQUARE INCHES OF THE WELLHEAD.e. MULTIPLY THAT NUMBER BY THE “SHUT IN” PRESSURE OF THE WELL. ADD ANY ADDITIONAL AMOUNT FOR REDUCING THE WATER LEVEL BELOW GROUND. SOUTH COUNTY WTP: IT WAS DOCUMENTED THAT THE SHUT IN PRESSURE OF THE WELLS ARE APPROXIMATELY 10.82 PSI (ABOVE LAND SURFACE), AND YOU WANT TO KILL THE WELL TO 10 FEET BELOW GROUND, ADD 10 FEET OF HEAD TO YOUR CALCULATION (10' / 2.31 FEET PER POUND PRESSURE = 4.33 POUNDS ADDITIONAL PRESSURE TO REDUCE) ADD THE TWO TOGETHER (10.82+4.33 = 15.15 PSI)f. MULTIPLY THE TOTAL PRESSURE REDUCTION NEEDED BY THE SQUARE INCHES OF THE WELLHEAD FROM ABOVE.(15.15 PSI X 201.1 SQ INCHES = 3,047 POUNDS FORCE)g. THE RESULTING NUMBER IS THE THEORETICAL AMOUNT OF WEIGHTING OR “KILL” MATERIAL NEEDED TO REDUCE THE WELLHEAD PRESSURE.4. CONNECT TO THE 6‐INCH DIAMETER BLOW‐OFF PIPE WITH THE PRESSURE LINE.5. MIX CALCULATED AMOUNT OF KILL MATERIAL PLUS 20%, IN MIXING TANK. IF USING SALT, MIX WATER AND SALT INTO BRINE SLURRY.6. OPEN APPROPRIATE VALVES AND PUMP KILL SOLUTION DOWN WELL.7. CHECK PRESSURES OR WATER LEVEL IN WELL.8. MIX ANOTHER BATCH OF BRINE OR KILL SOLUTION IF NECESSARY AND REPEAT THE PROCESS.9. MONITOR WATER LEVEL IN WELL AND ADD WEIGHT MATERIAL AS NEEDED.10. ONCE ALL REPAIRS/FABRICATIONS HAVE BEEN COMPLETED, THE PRODUCTION WELL(S) WILL NEED TO BE PUMPED TO BACKGROUND CONDITIONS. ALL DEVELOPED WATER MUST BE CONTAINED AND DISPOSED OF AT AN APPROVED LOCATION.NOTE: THERE ARE SEVERAL METHODS OF DETERMINING THE DIMENSIONS OF THE WELL. THE CALCULATION USED ABOVE IS ONLY ONE OF THOSE METHODS.

THE CONTRACTOR SHALL INSTALL A BUTTERFLY VALVE AT THE LOCATION SHOWN ON THE DRAWINGS AND SPECIFIED HEREIN.

Model 100SR

Description of Operation and MaterialsAPCO rubber flapper swing check valves are uniquely simple in design but durable for use on a variety of applications.

With only three major parts: Body, Flapper & Cover, there is relatively no maintenance. However, should maintenance be required, the flapper can be replaced in a matter of minutes. The valve body seat is on an angle of 45° to the centerline of the pipe, permitting horizontal or vertical flow up installation. With the flapper full open, there is a straight unobstructed flow passage, so all foreign matter is flushed away by the flowing medium. This eliminates clogging. Due to this unobstructed flow passage the pressure drop is considerably lower through the APCO Rubber Flapper Check than through conventional swing check valves.

Normally made of Cast or Ductile Iron, but readily supplied in Stainless Steel or Bronze, the valve can be lined or coated with various materials.

The flapper is normally Buna-N but can be compression molded from various synthetic rubbers. A steel disc for strength and a steel bar are molded inside the flapper. A hi-strength fabric is integrally molded over the disc and bar to form a flexible joint permitting millions of flexes without failure. For operation with aggressive media, Buna-N has excellent abrasion resistant qualities. When the valve is assembled the flapper is firmly clamped between body and cover. This feature eliminates problems of moving parts, shafts, pins, bearings, bushings, packings (as required in conventional check valves). Further, this flapper design eliminates jamming or sticking in the open position and the O-ring seal molded into the disc face assures positive sealing, even at lower pressures. Recommended for buried service with stainless steel cover bolts. Rated 125#/150# Class for 175 psi differential pressure. Higher pressure class available.

Backflow Device Optional Feature on 3" and LargerOften Pump Station Operators find it convenient to force open the Swing Check Valve by its outside lever, for the purpose of Backflushing, Priming Pumps, or to Drain the System. This is a dangerous procedure! The APCO Backflow Device meets OSHA requirements for safety because it is easily activated without risk of injury to operating personnel during a

backflow procedure. This Backflow Device is positive and will not slip during full backflow.

The Backflow Device can be removed for service without removing the check valve or taking the pump out of service. Size 3" and 4" (80 and 100mm) Backflow Devices are constructed of Bronze ASTM B-584 as approved by U.S. Navy for fleet service.

Should your next pump station design require a by-pass or backflow through the check valve for any reason…do it safely!

Specify APCO Series 100 Rubber Flapper Swing Check Valves with a Backflow Device.

104P3 StoryNotice there are two 4" (100mm) APCO Rubber Flapper Swing Check Valves!

Model 104 is a full size 4" (100mm) check valve for normal water service.

Model 104P3, designed specifically for raw sewage with a flow area thru the seat almost twice (23.76", 604mm) that of standard pipe (12.73", 323mm), permitting the 104P3 to pass a 3" (76mm) diameter solid as required by many states and municipalities for 4" (100mm) check valves used on sewage.

This feature is of special interest to sewage lift station designers.

Flow Control Option Need to Throttle or Shut-Off Flow?The Flow Control device is used to restrict the position of the flapper for the purpose of regulating flow into the system or to create a false head on the pump.

The device is mounted on the cover of the valve and when manually operated will prevent the flapper from fully opening. With this device, the Rubber Flapper Check Valve can be used as a stop check.

Proximity Switch Option Need a Signal That the Check Valve is Open?An inductive type Proximity Switch can be furnished mounted on the valve body with its target mounted internally on the flapper. This transmits an electrical signal indicating when the flapper is open or closed. Available on Series 100 and 100R.

APCO has manufactured Rubber Flapper Swing Check Valves (RFSCV) since 1965. We have many thousands of units in the field that have been operating successfully for decades. From time to time, engineers or end users have a difficult high head application where rapid flow reversal causes standard style Swing Check Valves to slam. The APCO 100SR was developed in 1978 to eliminate or minimize slam in these types of installations. The APCO 100SR has successfully managed surges (due to rapid flow reversal) even in tough vertical ‘flow up’ installations. See comparison graph on page 5.

The Standard Series-100 RFSCV has a 35º Disc Stroke and will close relatively quickly. This Stroke is very short compared to conventional Style Swing Check Valves which typically have 80º to 90º disc travel. When you add the spring return to the RFSCV it causes the disc to speed up or accelerate to valve closure. Having the Valve closed before reverse flow takes place can in many instances, drastically reduce or even eliminate valve slam.*

Comparison GraphComparison Graph

This graph compares the closing characteristics of the check valve with and without the spring assisted closure. The installation is vertical “flow up” and the power failure simulation for the test is identical. The pressure rise (blue line) generated from the valve closure without the spring assist is 120 psi. The pressure rise (black line) with the spring assisted closure is only 23 psi. This represents a 97 psi reduction in the pressure surge. Also, subsequent wave patterns are more subdued and rounded. On site closure noise (valve slam) and pipe displacement disappeared with the APCO 100SR.

The PDI is mounted to the cover and clearly identifies the position of the flapper.
