Kleiss MCS60-38 System Overview
Kleiss MCS60-38 System Overview
The Kleiss inflatable stopping systems meet the needs of the North
American Natural Gas LDCs by providing a flow control system that is
easy to use and effective at stopping off flow in various pipe materials
and a wide range of pipe diameters.
The Kleiss MCS60-38 System consists of four major components:
1) fitting to access the pipe, 2) tapping / completion tool, 3) inflatable stopper, and 4) stopping tool.
The Kleiss MCS60-38 System (all tools) has a maximum operating pressure of 60 psi. The inflatable stoppers have a
design safety factor of 3. The balance of the tools have a design safety factor of 2.5.
The Kleiss MCS60-38 System is designed to handle flow control on pipe sizes 3” to 8” on all pipe material – cast iron,
polyethylene, steel and PVC pipes. To accommodate the various pipe materials and sizes the tapping tool and stopping
tool are outfitted with the appropriate fitting, cutter, chute, and stopper. See the Sizing Table in Section 4.0 to identify and
install the correct components before operating the equipment.
The basic operation of the equipment is the same for all pipe materials. When working on non-metallic pipe materials,
make sure the equipment is grounded per your company operating practices.
(Kleiss & Co., who developed the system, has reviewed and approved this manual.)
