502 Stainless Steel Hot Tapping Service Sleeve

Double Strap Service Saddles

Responding to industry requests for a better product, JCM introduces the Model 502 Stainless Steel Service Saddle. The JCM 502 Stainless Steel Service Saddle is engineered with the pipe in mind. Heavy duty construction with balanced bolt design provides the pipe support, bolt torque and gasket compression necessary for a successful, long term saddle installation.

Material Specifications:

JCM 502 Stainless Steel Service Saddle Material Specifications
Band: 18-8 Type 304 Stainless Steel. Per ASTM A240
Outlet: 18-8 Type 304 Stainless Steel Threaded Half Coupling. Meets ANSI/AWWA C800 as applicable.
Bolting Assembly: 18-8 Type 304 Stainless Steel. Per ASTM A240
Lift Bar: 18-8 Type 304 Stainless Steel. Per ASTM A240
Fasteners: 18-8 Type 304 Stainless Steel.
Gasket: EPDM - excellent resistance to aging factors including ozone, oxygen, elevated temperatures and fl uctuations in weather. Recommended for service in hot water, steam and dry heat. Most popular application on chloramine. Suitable for other popular chemicals - ketones, alcohols, phosphate ester hydraulic fl uids, glycols, dilute acids and alkalis. Maximum temperature 300 F. wet.

Recommended For: IPS PVC, C-900 PVC, Ductile Iron, Cast Iron, Steel and other types of pipe.

Not suitable for petroleum and not recommended for High Density Polyethylene Pipe (HDPE).

Coated Double Strap Service Saddle with electro galvanized straps

This JCM Quality Fitting is equipped with 18-8 stainless steel bolts and nuts for superior corrosion resistance. When not properly handled it is the nature of stainless steel fasteners to gall and freeze (seize up). This is due to the inherent properties of the stainless material. Galling and freezing is often triggered by the presence of metal chips, burrs and grains of sand on the threads of the bolts and nuts. Extra care has been taken by JCM prior to assembly and packing of this fitting to assure a trouble-free installation.

1. The nuts and bolts are made from material of different hardness so that they have different strengths.
2. Standard 5/8” and 3/4” nuts are coated with a special blue or green (antiseize) coating. Additional lubricant may be needed. Uncoated stainless steel hardware is provided without lubrication to prevent a build up of dirt, sand or grit during shipment. A Molybdenum-Base lubricant is recommended.
3. Each nut is assembled by hand to be sure that it went on the bolt freely.
4. The bolts and nuts are handled carefully to avoid damage to the threads.
5. The bolts and nuts are made to exacting specifications to assure that the correct material is used and that the thread form is correct.

Stainless hardware is especially susceptible to galling. JCM supplies specially coated nuts to eliminate the galling caused by overtorquing, but the bolt threads must be kept clean, free from nicks and not pitched or thrown into the tool bucket during the installation process. Use of the JCM 901 Master Wrench or JCM 905 Torque Wrench with Deep Socket is highly recommended. Use of pneumatic wrench for installation could cause hardware to seize and is not recommended.

 

502 Double Strap Service Saddle Specifications:

Double Strap Service Saddles

Single band service saddle shall have a minimum material standard of 18-8 Type 304 stainless steel band, bolt assembly and hardware. Fabricated lug shall have permanently attached mutually supporting fingers and strong stainless steel lifter bar plate. Stainless steel studs, two (2) or three (3), shall be 5/8” and furnished with stainless steel washers to ensure proper torque readings. Stainless steel nuts will be coated with anti-seize coating to prevent galling. The gasket shall be EPDM material, gridded with raised outlet gasket with molded channels, and permanently adhered to the stainless steel band. Service saddle shall be minimum 8” in width. The stainless steel outlet shall be attached to the band by TIG weld process. Service saddle will be passivated per ASTM A380 with environmentally friendly process to return stainless to natural corrosion resistant state. Gaskets shall be tapered to maximum 1/4” thickness. Service saddles shall be JCM 502 or approved equal.

Double Strap Service Saddles TORQUE VALUES

1. Clean and scrape pipe. Remove any scale, pipe wrap, debris or dirt that may interfere with the complete sealing of the gasket around the outlet area. Inspect pipe for integrity, size, outside diameter and surface irregularities. Confirm the proper size and range of service saddle. Inspect fitting to ensure all parts are included. Fitting furnished with stainless steel hardware; see reverse for fastener management.

2. Lubricate the pipe and the fitting gasket with soapy water. Do not use oil base pipe lubricant.

3. Open the service saddle by loosening (without removing) the nuts to the top of the stainless studs/bolts. Disengage the locking “C-Plate” and lift plate to open saddle. Wrap service saddle around the pipe positioning the outlet in the proper position on the pipe. Do not rotate the saddle when the gasket is engaged and seated on the pipe, this may cause the gasket to seat improperly.

4. Loosely close the saddle around the pipe by lifting the C-Plate(s) lip over the lug system stainless receiver bar, meeting the stud and fingers, and lock in place.

5. Complete tightening of the saddle by squeezing the lugs together and tighten the nuts. Two stud saddle: alternate from one end to the other for equal gap between saddle halves. Three stud saddle: start at the center bolt and work out toward saddle ends, alternating across from one end to the other for equal gap between saddle halves. Continue tightening sequence to reach the appropriate torque levels.

6. Tighten the nuts evenly with a hand wrench to the following torque values. To ensure proper torque level, wait 15 minutes and retighten to recommended torque. Trick of the Trade: Pneumatic wrenches could cause the stainless nuts to seize on the stainless steel studs. 5/8” Bolts/Studs tighten to 75 Foot Pounds of Torque*

7. Proceed with tapping process.

*Ensure proper torque level with a field grade torque wrench equal to the JCM 905 Torque Wrench. Thin wall, small diameter & flexible types of pipe are subject to many variables which affect torque values. Use discretion when tightening fittings on thin wall, small diameter & flexible pipe in order to not crush or severely deform the pipe.
