For Your Safety It is solely the responsibility of the system designer and user to select products suitable for their specific application requirements and to ensure proper installation, operation, and maintenance of these products. When selecting products, the total system design must be considered to ensure safe, trouble-free performance. Material compatibility, product ratings and application details should be considered in the selection. Improper selection or use of products described herein can cause personal injury or property damage. Contact your authorized HOKE sales and service representative for information about additional sizes and special alloys. SAFETY WARNING: HOKE products are designed for installation only by professional suitably qualified licensed system installers experienced in the applications and environments for which the products are intended. These products are intended for integration into a system. Where these products are to be used with flammable or hazardous media, precautions must be taken by the system designer and installer to ensure the safety of persons and property. Flammable or hazardous media pose risks associated with fire or explosion, as well as burning, poisoning or other injury or death to persons and/or destruction of property. The system designer and installer must provide for the capture and control of such substances from any vents in the product(s). The system installer must not permit any leakage or uncontrolled escape of hazardous or flammable substances. The system operator must be trained to follow appropriate precautions and must inspect and maintain the system and its components including the product(s) and at regular intervals in accordance with timescales recommended by the supplier to prevent unacceptable wear or failure. We recommend that the regulators will be serviced every 5 Years after first installation.
Flareless Tube Fittings Data Charts Design GYROLOK Flareless Tube Fittings have been carefully designed and manufactured to provide a wide range of outstanding leak-tight application capabilities. GYROLOK ratings and specifications are as follow: Pressure Ratings GYROLOK fittings are rated for working pressures higher than the tubing recommended for use with GYROLOK. However, tubing should not be used above its maximum allowable working pressure. Maximum allowable working pressures for tubing suitable for use with GYROLOK are identified herein. If no pressure is identified for a given size and a wall thickness, then that tube size/wall combination is not suitable for use with GYROLOK fittings. See caution below. Vacuum Rating GYROLOK offers excellent vacuum capability. With good quality tubing, GYROLOK fittings will be leak-tight at vacuum levels of 0-9 torr while tested with a leakage sensitivity of 0-9 sccs. Materials GYROLOK & GYROLOK-XP fittings are available in brass, 04 and 6 stainless steel, MONEL, HASTELLOY, INCONEL & INCOloy, titanium, 2205 Duplex, 2507 Super Duplex and 254 SMO. Contact your local HOKE distributor for further information. Fully annealed tubing to the specifications identified herein are suitable for use with GYROLOK fittings. The tubing selected, whether metallic or nonmetallic should be compatible with the process fluid, temperature and applications. The wall thickness selections should be based on pressure and temperature conditions. should always be fully annealed. While welded tubing may be used with GYROLOK, inconsistencies in its manufacture and performance are sometimes encountered. As a result we recommend the use of seamless tubing. For proper fitting performance, the tubing surface finish should be good, free from nicks or scratches. Do not use out of round tubing which does not easily go through fitting components. Fitting performance is maximized when tube ends are squarely cut, using a tubing cutter, and deburred. Proper fitting performance demands that the fitting be significantly harder than the tubing on which it is used. For example, stainless steel tubing should never exceed a maximum surface hardness of Rockwell B90, while MONEL tubing should never exceed a maximum surface hardness of Rockwell B75. Gas Service Gases (air, hydrogen, nitrogen, etc.) can escape through smaller leak paths than liquids. As such, the reduction of surface defects (scratches) on tubing becomes more important when the system media contains gases. As tubing wall thickness increases, the ability of the ferrules to coin out imperfections increases. The use of heavier wall tubing will help the ferrules to overcome minor surface defects that could contribute to gas leakage. HOKE recommends the following minimum wall thickness for tubing when system media contains gases. Tube OD (inches) Nominal Minimum Wall Thickness (inches) /8 0.028 /6 0.028 /4 0.028 5/6 0.05 /8 0.05 /2 0.049 Tube OD (inches) Nominal Minimum Wall Thickness (inches) /4 0.065 7/8 0.08 0.08 /4 0.09 /2 0.4 2 0.80 Suggested Allowable Pressure Tables Figures and tables are for reference only. HOKE makes no implication that these valves can be used for design work. Applicable codes and practices in industry should be reviewed and considered. ASME Codes are the successor to and replacement of ASA Piping Codes. For combinations not shown, consult factory. gyrolok
Calculating Yield, Burst, and Maximum Allowable Working Pressures Maximum allowable stress values and calculation factors are used to determine yield, burst, and maximum allowable working pressures. HOKE has made these calculations for a variety of materials and included the results in charts beginning on page 6. The following information is presented to provide an understanding of how the numbers are derived. Formulas. Maximum Allowable Working Pressure Fractional: Factor Maximum Allowable Stress Valve (psi) Metric: Factor Maximum Allowable Stress Valve (psi) 0.06895 Factor Maximum Allowable Stress Value (ksi) 68.95 2. Calculated Yield Pressure Fractional: Factor Minimum Yield Strength (psi) Metric: Factor Minimum Yield Strength (psi) 0.06895. Calculated Burst Pressure Fractional: Factor Minimum Tensile Strength (psi) Metric: Factor Minimum Tensile Strength (psi) 0.6895 See table of Maximum Allowable Stress Values for Material at Various Temperatures on pages and 4, and the Calculation Factor Tables on page 5. Maximum Allowable Working Pressure Calculation Examples The values listed on the CALCULATION FACTOR TABLE are for stainless steel and may be used to determine the maximum allowable pressure, yield pressure, burst pressure or any other pressure for which a stress value is available. The Calculation Factor Tables on page 5 are based on stainless steel tubing having maximum allowable outside diameter and minimum allowable wall thickness. Stress values may be obtained from MAXIMUM ALLOWABLE STRESS VALUES FOR MATERIALS AT VARIOUS TEMPERATURES table or other sources. All of the charts contained herein are based on use of tubing having the worst tolerance conditions allowed for that particular material. Example Suppose that you want to know the maximum allowable working pressure of 04 S. ST. seamless, ASTM A-2, ¼ O.D. by.05 wall tubing at a temperature of 00 F. This information can be directly obtained from the table MAXIMUM ALLOWABLE WORKING PRESSURE 04 STAINLESS STEEL or calculated as follows: First Find the factor (K) corresponding to ¼ O.D. 0.05 wall on the CALCULATION FACTOR TABLE. K = 0.275 Second Find the allowable stress (S A ) for seamless 04 stainless steel tubing at 00 F on the MAXIMUM ALLOWABLE STRESS VALUES FOR MATERIALS AT VARIOUS TEMPERATURES. S A = 8,750 psi Third According to CALCULATION FACTOR TABLE, Maximum Allowable Working Pressure (P A ) = Factor (K) Maximum Allowable Stress (S A ) Value in psi Therefore: P A = K S A P A = 0.275 8,750 psi P A = 56 psi (Max. Allowable Working Pressure at 00 F) Example 2 Suppose that you want to know the maximum allowable working pressure of 04 stainless steel seamless, ASTM A-2, 6mm O.D. by.2mm wall tubing at a temperature of 8 C. This information can be directly obtained from the table MAXIMUM ALLOWABLE WORKING PRESSURE 04 STAINLESS STEEL or calculated as follows: First Find the factor (K) corresponding to 6mm O.D..2mm wall on the CALCULATION FACTOR TABLE. K = 0.42 Second Find the allowable stress (S A ) for seamless 04 stainless steel tubing at 8 C on the MAXIMUM ALLOWABLE STRESS VALUES FOR MATERIALS AT VARIOUS TEMPERATURES. S A = 8,750 psi Third According to CALCULATION FACTOR TABLE, Maximum Allowable Working Pressure (P A ) = Factor (K) Maximum Allowable Stress (S A ) Value in psi 0.06895 Therefore: P A = K S A 0.06895 P A =.42 x 8,750 psi 0.06895 P A = 52 bar (Max. Allowable Working Pressure at 8 C) CAUTION: Limited test data is available on certain materials, including HASTELLOY, INCONEL, 2205 Duplex, and 254 SMO. In such applications, further testing either by HOKE or by the user is recommended to assure fitting suitability for the application. 2
