JCM 415 Tapping Sleeve for Concrete Steel Cylinder Pipe Many agencies have special requirements which are modifications of our standard design. JCM’s manufacturing flexibility makes it possible for us to offer a great many modifications without delay in product availability. Some of the more popular options on these sleeves are:
A solid back half in lieu of straps (Type II) for Pretension Concrete Cylinder Pipe. Entire sleeve and outlet epoxy coated with stainless steel straps. Different locations of the grouting holes.
JCM 415 Tapping Sleeve for Concrete Steel Cylinder Pipe - Typical Specification Tapping Sleeves for Concrete Steel Cylinder Pipe shall be in accordance with AWWA Manual M-9. They shall also meet AWWA C-301 and C-303 Standards pertaining to design, manufacturing quality tests and welders qualifications. Manufacturers shall have manufactured this type of tapping sleeve for a minimum of ten (10) years. The sleeves shall have a separate gland which permits installation of the sleeve prior to the cutting of the prestress wires. The gland shall have a fusion epoxy coated (per AWWA C-213) waterway, and a minimum 7/8” wide hydromechanical gasket set in a retaining machined groove of a pressure plate. For outlet sizes 14” and larger, the gasket groove must be consistently positioned about throat of tapping waterway. Inside diameter of the gasket groove must be set back a minimum of 1” from the waterway to allow dispersal of forces generated by gasket compression. Gasket grooves machined in a circle and formed to an elliptical shape will not be an accepted equal. The pressure plate shall be gusseted to the draw flange to eliminate flexing. The gland shall be equipped with load bearing set screws to protect the cylinder. Sleeves shall be furnished with grouting seals and grout horns to facilitate filling the space between the sleeve and the pipe. Tapping Sleeves shall be JCM 415 Tapping Sleeve or approved equal. Tapping sleeves shall be ANSI/ NSF Standard 61, Annex G and ANSI/AWWA 372 Certified. JCM 415 Tapping Sleeve for Concrete Steel Cylinder Pipe - Material Specification BODY: Carbon Steel per ASTM A-36, ASTM A-516 Grade 70 or equal. FLANGE: Combination flange with ANSI 150 lb. Drilling, recessed for tapping valve MSS-SP60 GASKET: Compounded for use with water, salt solutions, mild acids, bases and sewage. BOLTS: Corrosion resistant, high strength low alloy A242. DRAW HARDWARE: B7 Material Optional Stainless Steel, 18-8 Type 304. FINISH: Heavy coat of corrosion resistant shop coat primer on sleeve, gland and straps. Waterway of gland is epoxy coated (fusion applied per ANSI/AWWA C-213). Optional Fusion Epoxy Coating on entire sleeve. JCM Industries Tapping Sleeves meet or exceed the ANSI/AWWA C-223 and MSS-SP 124 Standards as applicable. JCM Industries recommends a template of the outside diameter of the pipe surface on all taps with an outlet of 24” or larger, on all taps where the outlet is more than 60% of the pipe size, on pipe which out-of-roundness is suspected and on high-pressure taps where the fit of the sleeve is critical to the high pressure performance. Instructions for this procedure are available from JCM upon request.
