The Kee Klamp Fitting

The simple but effective engineering principle of the Kee Klamp fitting is the foundation of the most versatile pipe connection system available. There are many variations of fitting to suit a wide range of applications, thus providing the versatility to achieve virtually any structural configuration.

Kee Klamp fittings are malleable iron castings manufactured to the requirements of ASTM A47-77-32510. A range of fittings to suit eight sizes of pipe is available. A simple hex key (see type 99) is the only tool required to create a strong, rigid joint. A recessed set screw, tightened by the hex key, firmly locks the pipe into the fitting. Set screws are manufactured in case hardened steel and are protected against corrosion by Kee KoatTM.

A Kee Klamp fitting (size 5 to 9) can support an axial load of *2000 lbs. per set screw with the set screw tightened to a torque of 29 lbs./ft.** This is normally obtained when the set screw is fully tightened using a ratchet wrench.

* rating includes a safety factor of 2:1
** The exception to this torque specification is size 6 Kee Lite (Aluminum) fittings. The recommend set screw torque value for size 6 Kee Lite is: 19 ft/lbs. [more info]

Pipe

Kee Klamp fittings are produced in a range of standard sizes to suit Schedule 40 steel pipe, sizes 1/4" nominal bore to 2" nominal bore; also equivalent sizes of tubing in other materials.

Tubing of other specifications can be used, providing the outside diameter is compatible with Schedule 40 Pipe. Pipe with a wall thickness of less than 1/8'' can only be used in lightly-loaded structures.

Pipe sizes are shown in the table and sectional drawings below.

Finishes

Kee Klamp fittings are supplied hot dip galvanized to ASTM A153. Standard steel pipe is galvanized to the requirements of ASTM A53.

Colors

In addition to this standard finish, pipe fittings and accessories can be supplied with polyester coating in any RAL color. [Download RAL Color Chart]

The polyester coating is highly durable and is usually applied to products that are already galvanized. Should damage occur to the coating, corrosion is still prevented.

Quality Assurance

Quality is the overriding priority when manufacturing Kee Klamp fittings. It begins in the foundry where all fittings are manufactured and galvanized to American Standards for Testing and Materials (ASTM) Requirements, and subject to stringent inspection upon completion. Kee Klamp manufacturing facilities are ISO 9001 registered.

TÜV Approval

TÜV, Europe's leading Independent Testing House, has approved the following Kee Klamp fittings in sizes 5 to 9:

10, A10, 12, A12, 14, 15, 16, 17, 19, 20, 21, A21/A26, 25, 26, 27, 28, 29, 30, 35, A35, 40, A40, 45, A45, 46, F50, M50, M51, M52, BC53, 55, 56, M58, 60, 61, 62, 63, 64, 65, 67, 68,70, 75, 86, 87, 88, 89, 114, 121, 145.

For an up to date TÜV listing see our website at http://www.keeklamp.com

The maximum load of each fitting type is as stated on the TÜV Certificate, a copy of which is available upon request. The technical descriptions featured in this manual have not been part of the testing.

Due to possible dynamic load influences, some structures will need to be checked at regular intervals to ensure set screws are correctly tightened.

Health and Safety

No Kee Klamp fittings have been found to be hazardous within the meaning of current OSHA Regulations, assuming that the materials are cut and assembled using normal pipe cutters, saws and hexagonal keys.

Kee Klamp fittings are designed so that the need to weld is avoided - an added safety element since the welding process does have OSHA implications, especially if the pipe is pre-galvanized or has any other pre-finish.

Specifying Kee Klamp Fittings

The information contained in this manual includes everything required to produce a full specification.

Every fitting is illustrated and accompanied by a table of sizes and weights. Each fitting has a simple numerical code reference, which is unique and differentiates it from every other fitting. The code defines the type of fitting and the pipe size, or sizes, it is designed to receive.

The first number, preceeding the dash (-) identifies the type of Kee Klamp fitting.

A single digit, following the dash, defines pipe size. Two digits after the dash indicate that the fitting is designed to receive two sizes of pipe. Likewise, three digits after the dash indicate that the fitting is designed to receive three sizes of pipe. The Kee Klamp pipe size codes (a choice of eight, numbered from 2-9) are shown on pages 4 and 5 of this manual, where the Kee Klamp pipe code is related to actual pipe dimensions. (See table above).
