MODEL 7041 FLANGE ADAPTER –

ANSI CLASS 125/150

The Model 7041 Flange Adapter allows for a direct connection with ANSI class 125/150 flanges. The specially designed gasket enables the transition from a grooved system to a flanged system or component with this single flange adapter. The two-segment design provides an easy and fast installation. 2” through 12” flange adapters are supplied hinged as a single assembly, while 14” - 24” (Model 7041N) are supplied with two separate segments and a draw kit. All include an EPDM rubber gasket and plated track bolts and nuts. Housing segments are supplied with our standard painted finishes, i.e. orange or RAL3000 red. Optional finishes such as hot dipped zinc galvanized and custom epoxy coatings are available.

Always use factory-supplied bolts and nuts to assemble flange segments. The use of other bolts may cause of joint failure.

Always fasten the bolts to the required torque. Please refer to page 3.

For Fire Protection pressure rating, listing, and approval information, refer to Data Sheet B-42 or visit SHURJOINT website, www.shurjoint.com for details or contact your SHURJOINT Representative.

* Working Pressure is based on roll grooved standard wall carbon steel pipe.

Important Notes:

1.The Model 7041 flange adapter requires a hard flat face for effective sealing. When the mating surface is not adequate as with the serrated faces of some valves or the rubber-faced wafer valves, a sandwich plate (Model #49, see cut sheet #V-03) must be used.

2.The Model 7041 flange adapter has small triangular teeth inside the key shoulder to prevent the pipe from rotating.

The teeth should be ground off when mating to a rubber-lined flange.

3.The Models 7041 flange adapter shall not be used as anchor points for tie-rods across non-restrained joints.

4.When assembling a Model 7041 flange adapter against a butterfly valve or ball valve, make sure that the outside diameter of the flange adapters do not interfere with the valve actuator or the mounting pad of the actuator.

5.Bolt tightening sequence: Like a regular flange joint, it is important to make flange faces contact parallel. Tighten nuts alternately in the sequence of diagonally opposite pairs as shown below until the flange faces meet and make a metal-to-metal contact.

Performance Data

The following tables show the maximum working pressures (CWP) of Shurjoint Model 7041 Flange Adapter ANSI Class 125/150 used on both carbon steel and stainless steel pipes. Shurjoint ductile iron couplings can be used in conjunction with stainless steel pipe in non-corrosive environment as the flow media does not come in direct contact with the coupling housings but rather only the gasket.

Required Bolt Torque

The table below provides the standard torque values for proper assembly of Shurjoint flange adapters. Use a torque wrench so that all the nuts are tightened equally with a same torque value. Shurjoint flange adapters are sealed with elastic (rubber) gaskets, which require much lower torques than those that utilize metallic gaskets.
