Can the tool be used on service items other than the natural gas industry?
|
Yes. The medium can also be liquids as long as the fitting type or configuration is suitable for tool attachment.
|
|
Is there a stub left on the main line after the service tee is removed?
|
Yes. There is an approximately 4 cm stub that houses the drive in and welded tapered plug. Owners may decide to utilize different tee closure devices such as threading the stub.
|
|
What are some of the tool uses?
|
The tool can be used to eliminate worker exposure to hazardous releases of natural gas when performing work on main line service tees. The tool can be fitted onto the service tee to either remove the service tee or perform downstream work and return the tee to service. Service line alterations, dresser style compression fitting removals, etc. are possible without the release of natural gas. The tool is currently capable of interrupting fluid service to replace defective full port valves. The tool eliminates the need to shut down the main line or install stopper fittings on the main line to perform work on service tees and service line piping. There is a significant reduction in excavation size compared to the space necessary to install main line stopper equipment. |
|
What is the maximum rated operating pressure of the tool?
|
The tool is currently rated for a maximum operating pressure of 550 kPa, (80 psi ).
|
|
What is the tools intended purpose?
|
The tool was built to address the difficulty in safely stopping homemade open gut or other manufactured service tees to service lines in the natural gas industry. The tool is capable of interrupting the supply of gas to service lines to perform service tee removals or alterations to service tees and down stream service lines thereby avoiding the stopping of main gas lines. Eliminating worker exposure to hazardous releases of natural gas was a main driver in the development of the tool technology. Releases of gas into the atmosphere was also a consideration in reducing Green House Gas (GHG) emissions. |
|
What safety provisions are incorporated into the tool design?
|
The tool is patented in North America and certified by a Professional Engineer. The tool utilizes an effective compression style sealing force to retain the tool onto the piping below the service tee cap. Any exposed threads below the cap are a benefit to the tool retaining capability. There is an added adjustable security retainer device to ensure no tool movement. Threaded adapters are used for Mueller No-blo tees with the brass completion plugs intact. Threaded adapters are also used on threaded piping. |
|
What size main lines can the tool be used on?
|
Any size. Contact the supplier to discuss alternate service tee types or applications of service.

Web Site Updates
|
|
We have updated our website to better reflect the new tool capability. The text and images found in the street tee connections are easier to follow and provide greater detail. The appropriate images and part numbers have been added for further clarity of the tool components. |

New Attachments - Greater Capability
|
|
Mazco has expanded the Safe-T-Stopper capability to service and remove street type threaded tees up to 2”. A new lower housing and main seal allows for the street tees to be unthreaded from the cast iron or steel mains and a plug threaded in its place. We can even put in a new threaded tee and sch 80 pipe nipple in place of the old tee. Upgrading and insertions of service lines can be done safely and cost effectively. |

Tool Improvements
|
|
Based on customer feedback we are pleased to announce that we have modified the expander tool shaft size to enter small bore home made 3/4" service tees and 3/4" Mueller No-Blow service tees. This change no longer requires the use of the expander tool extention. |

New capability
|
|
Safe-T-Stopper™ is now also availabel to adapt on to 1" and 1¼" threaded street tee service connections. Tees that are threaded into couplings on steel mains or threaded directly into cast iron can now be removed without the realese of natural gas. |
