SHURJOINT XH-1000 Extra Heavy Duty High Pressure Rigid Coupling

GROOVED COUPLINGS

Gasket Installation – Preliminary Steps

1. INSPECT PIPE ENDS: For optimum sealing by the gasket, the exterior surface of the pipe ends must be free from any indentations, pro-jections, roll marks or other harmful surface defects such as loose paint, scale, dirt, chips, grease and rust.

2. CHECK GASKET: Verify the gasket supplied is correct for the intended service. Color code identifies gasket grade.
   Refer to page 36 for additional information on gaskets.

3. LUBRICATE GASKET: To help insert pipe smoothly and mount couplings smoothly with-out pinching, apply a thin layer of Shurjoint Lu-bricant to the sealing lips of the gasket and as well as to the exterior of the gasket. Other com-patible lubricants may be used so long as they are not harmful to the gasket. System tempera-ture should also be considered when selecting a lubricant. See page 38 for details.

4. INSTALL GASKET: Install the gasket over one end of the pipe so that the pipe end is exposed. No part of the gasket should overhang this end of the pipe.

5. BRING THE MATING PIPE TOGETHER: Bring together and align the two pipe ends to be joined. Slide the gasket over the ends and center it between the grooves of the pipe to be joined. No part of the gasket should protrude into the groove of either pipe.

Model XH-1000 Extra Heavy Rigid Coupling

Please read these instructions carefully before installation.

1. Refer to page 50 for preliminary steps 1,2,3,4 & 5.

2. ASSEMBLE COUPLING: Start with the two coupling halves separated.

3. ASSEMBLE COUPLING HALVES: Install one half at a time over the gasket making sure that the coupling keys engage the grooves.
   WARNING: The Shurjoint Model XH-1000 couplings feature a tongue and groove design and mechanism. Thus the couplings must always be installed so that tongue and groove mate properly. Attempt-ing to install these couplings tongue to tongue or groove to groove will result in joint failure, property damage or serious injury.

4. INSERT BOLT & NUT: Insert the first bolt and apply the nut hand tight. Insert the second bolt and nut in the same manner making sure that the oval neck of both bolts engage the holes in the coupling housing.

5. TIGHTEN NUTS: Sizes 2” through 4” have a torque requirement (refer to the table below). It is normal to see some small gaps between the bolt pads. Bolt pad gaps should be equal on both sides of the coupling.

For sizes 6” to 12”, tighten nuts alternately and equally until the bolt pads meet and make metal-to-metal contact. Tighten nuts by another one quarter to one half turn to make sure the bolts and nuts are snug and secure. The use of a torque wrench is not required.

CAUTION

1. Uneven tightening of bolts and nuts may cause the gasket to be pinched, resulting in an immediate or delayed leak.
2. Never exceed torque stated in the table on page 34. Excessive tight-ening of nuts may cause a bolt or joint failure.

Note: Couplings in sizes of 10 inch and larger, when used on schedule 10S or 5S stainless steel pipe, shall be torqued beyond the metal-to-metal contact to the torque range stated, for the bolt size used, in the torque table located on page 34 of the 2017 installation instructions.
