SUBMITTAL HEAVY-DUTY HD NO-HUB COUPLINGS

Transcription

1 Architect Contractor SUBMITTAL HEAVY-DUTY HD Date Project Engineer The patented PROFLO Heavy-Duty HD No-Hub Couplings are engineered to connect no-hub cast iron pipe in applications replacing the less-efficient hub & spigot material. The Coupling consists of an elastomeric compound gasket (ASTM C-564) housed inside a 304 stainless steel corrugated shield. Depending on the size of the shield, (4) or (6) 304 stainless steel clamps surround the shield and provide the sealing force. The 3/8 hex-head screws are made from 305 stainless steel. The PROFLO Heavy-Duty HD No-Hub Couplings are available in sizes ranging from 1 1/2 10. The couplings are designed to be torqued to 80 in-lbs. The entire coupling is corrosion resistant. Conforms to ASTM C1540.

Our patented, extra wide bi-directional shield is now constructed with a heavier gauge stainless steel. The mechanically interlocked 9/16 wide clamps have also been augmented with a heavier gauge stainless steel and a 3/8 hex-head screw. These changes, teamed with our specially beaded gasket, enable our new Heavy-Duty HD coupling to exert exceptional hold on the pipe for a positive, reliable seal. Conforms to ASTM C1540. The Gasket Made from high-quality elastomeric compound (ASTM C-564), the PROFLO No-Hub gasket features a pattern of multiple thick sealing sectors and adjacent groove sectors laterally spaced. When the clamps are tightened, this pattern permits the clamping bands and the shield to form a restriction impeding the movement of the shield relative to the gasket. The Shield thick type 304 stainless steel green shield requires less band load to transfer pressure to the gasket, leaving more clamping load in reserve to compress the gasket. The patented, bi-directional corrugations create clamp sealing pressure in both parallel and transverse patterns on the gasket and pipe, thereby avoiding pull-out failures, and providing a positive, reliable seal. The Clamps Heavy-duty 304 stainless steel clamps and 3/8 hex-head 305 screws provide the sealing force. 1-½ through 4 couplings use four (4) clamps; 5 through 10 couplings use six (6) clamps. The entire assembly is corrosion resistant. 04/03/07 BB

Shield thickness Gasket: The gasket is made of an elastomeric compound that meets the requirements of ASTM C-564. The PROFLO patented Heavy-Duty HD No-Hub Coupling has been engineered to provide a heavy-duty, all stainless steel coupling; balancing the desire for a more rigid joint with the need to provide a superior, positive seal which can accommodate possible disparities in the mating of No-Hub pipe and fittings. This has been accomplished by manufacturing our Ideal patented No-Hub Heavy-Duty HD coupling with a heavyduty corrugated shield of sufficient width to accommodate additional surface-bearing sealing clamps. The additional sealing clamps, when torqued to 80 in-lbs., deliver additional performance benefits. First, the overall dimensional thickness of the clamp and shield, in conjunction with the additional width of the coupling, result in a more uniformly rigid joint, with the load being supported at both the outer edge of the coupling and the centerline of the joint. Second, the additional sealing clamps yield increased surfacebearing contact between the coupling and the pipe or fittings, thereby inhibiting joint movement at higher internal pressures not commonly associated with DWV systems. The 1-1/2, 2, 3 and 4 diameter couplings consist of a 3 wide bi-directional, corrugated 304 stainless steel shield in conjunction with four (4) stainless steel clamps mounted in a series, secured in place by means of fixed and floating eyelets to allow the clamp travel during tightening. The 5, 6 8 and 10 couplings consist of a 4 corrugated 304 stainless steel shield and six (6) stainless steel clamps. All PROFLO patented Heavy-Duty HD No-Hub Coupling are designed to be installed with a pre-set torque wrench calibrated at 80 in-lbs. to accommodate the 305 stainless steel 3/8 hex-head/shoulder screw. 04/03/07 BB

4 Larger Hex Head Screw The 3/8 hex head screw is designed to apply the full load of 80 in. lbs. of installation torque to the band/shield assembly. Specially Beaded Gaskets The heavy-duty coupling utilizes a specially beaded gasket that mates with the shield and clamping forces for superior sealing pressure and holding power. PROFLO gaskets comply with ASTM C564. Floating Eyelet Design Floating eyelets fasten the clamps to the shield, allowing the clamp band and shield to move independently. This freedom prevents the shield from crimping during tightening, which can lead to leakage later on. Mechanical Interlocking Clamp Design PROFLO clamps feature a one-piece screw housing that mechanically interlocks the housing to the band. This one-piece housing design eliminates leak paths that can occur in staked or welded clamps. Green Shield The distinctive green shield quickly identifies the PROFLO Heavy-Duty Couplings.

This patented* shield design adjusts to differences in the circumference and outside diameters of the pipes being joined. This eliminates gasket wrinkling and thereby eliminates leak paths. These bi-directional corrugations also create sealing pressure in both parallel and transverse patterns on the gasket and pipe. This works to avoid pullout failures and provides a positive, reliable seal. *U.S. Patent N. 5,431,458
