Team’s Hot Tap Services (HTS)

T

eam’s hot tap services have been utilized worldwide for making branch connections into operating heat exchangers, vessels, columns, tanks and pipelines. Tapping operations performed by experienced technicians begin only after detailed coordination and planning have been completed with plant personnel. Designed by exper t engineers, Team’s hot tap entry process can be performed in a wide range of conditions. For line diameters small and large, from cryogenic to severe heat, from a vacuum to ex treme pressure, Team’s proven technology is safe, reliable and cost-effective.

A line stop, or plug off, is used to stop the flo w of product once access is gained through a hot tap. The procedure enables pipelines and plant piping systems to be isolated for repairs or additions without causing an interruption in service or loss of product. Team’s line stops are used extensively by petrochemical plants, refineries, municipal water districts, hospitals, steel mills, nuclear power plants and pipeline operating companies. Team line stops can be per formed on a broad range of pipe sizes for low, medium and high pressure s ystems. Technicians begin by designing a customized full encirclement saddle, which eliminates pressure-bearing fillet welds and reduces potential leakage. Once the hot tap and line stop are performed, the valve is removed by installing a completion plug in Team’s SealTite® _flange.

Team’s line stop plug provides a bet ter, safer seal on all types of pipe. Unlike other seals that rely solely on an O -ring, the SealTite® _{metal-to-metal seal provides a}

more secure closure, and uses an O-ring as a backup for higher temperatures. If f uture access to the pipeline is ever ne cessary, a safe reentry and reseal can be executed through the same closure flange.

Team’s Line Stops & Hot Stops

Team’s custom-designed full encirclement split tee fitting is applied.

Team’s SealTite®_{flange is installed and the}

valve is removed. A process-compatible plug is inserted to block

and stop product flow.

Team technicians cut a hole into the pipeline.

Through-the-Valve Stop: Ideal for non-functioning valves on tanks and vessels

Across-the-Header Stop: When clearance limitation will not allow normal line stopping methods

Elbow Stop: When an angle tap is

needed at the curve of a pipeline Tee Stop: A special SealTite

®_fitting

installed on the back side of the tee

Double Line Stop

A double line stop occurs when work is needed on a larger sec tion of a pipeline. Two SealTite®_{fittings are welded to the}

pipe and two line stop taps are completed. Once the line stops are set and the pres-sure is vented, repairs can take place between the two plugs. Lines stops are then equalized and removed, and Team’s SealTite® _{completion plugs are installed.}

Double Block and Bleed

A double block and bleed is used when added security is needed. The primary line stop holds the pressure while the second-ary line stop ensures a 100% safe seal. Upon completing the necessary repairs downstream of the double block, techni-cians seal the pipe with Team’s SealTite®

HiStop

®

_Services

Sizes 1/2” to 16” (15 mm to 406 mm) Temps to 1,100°F (593°C)

Pressure to 2,600 psig (179 bar)

Team’s patented high temperature, high pres-sure (HTHP) Hi-Stops®_{are used primarily to}

solve maintenance and engineering problems where operating conditions exceed conventional line stop ranges. Team has successfully stopped a 6-inch boiler feedw ater line leaking water at a rate of 1,650 gpm and flowing at a velocit y of  22 ft/sec. The line’s pressure was 2,100 psig at a temperature of 400°F.

Team utilizes patented techniques and equipment to achieve the most secure line stop possible in extreme circumstances. The advanced HiStop method incorporates a special HiStop fitting, and a precision cutting and reaming operation that creates a tapered hole through the pipe. The opening is then fit ted with a precision-ground tapered steel plug that permits depressurizing of the systems for the necessary maintenance. A metal-to-metal seal secures the connection between the plug and the line.

T

eam’s Freeze Stop services are an eco-nomical and nonintrusive method used to isolate a piping system. Liquid nitrogen piped into a standard stainless or aluminum freeze jacket bolted to the pipe means no permanent modifications are made to the system. A clean, quick and simple freeze stop blocks f luid while a repair is in progress downstream. This safe, reliable solution does not inflict any undue tension on the pipe wall, nor does it affect the metallurgy of the pipe.

Applications

• Piping systems up to 30” (750 mm) • Pressures to the rating of the pipe • In close, confined areas with proper

ventilation

• Three times the piping diameter away from mechanical connections

• Five times the diameter of the pipe away for welded connections

Requirements

• Pipe materials must be suitable for freezing such as carbon steel, stainless steel, cast iron, copper and aluminum

• Line must be full of liquid and have no flow • Process liquid freeze point must be evaluated

Pipeline Pigging Wye

T

eam’s Pipeline Pigging Wye is an innovative solution for launching and retrieving pigs. The primary purpose of pipeline pigging systems is to clean pipelines and to obtain vital information concerning the integrity of  the pipeline. Most oil and gas pipelines have launch and receive stations perma-nently installed primarily to remove the various contaminants from the pipeline wall. Pipelines can be unpiggable for a variety of reasons including:

• Changes in diameter

• Presence of unsuitable valves (reduced orifice plug valves)

• Tight or mitered bends (less than three diameters)

• Low operating pressure • Low flow or absence of flow

• Lack of launching and receiving facilities • Dented or collapsed areas

• Excessive debris or scale build-up Typical launch and receive stations are a large investment in piping and facilities with little payback. They require a large permanent footprint with possible land acquisition and require ongoing mainte-nance of the facilities. The Team Pipeline Pigging Wye can help eliminate the

challenges associated with traditional pigging operations.

Water and Wastewater

T

eam provides a diverse range of  specialty services fo r the Water and Wastewater industry. With a strong focus on municipalities, Team has the personnel, technical expertise and special equipment needed to deliver reliable, cost-effective solutions where and when you need them.

Live Valve nsertion

Team’s patented InsertValve™ delivers value, reliability and performance second to none. This field proven valve installs under pressure, eliminating the need for line shut downs in the event of planned or emergency valve cut-ins.

Designed for a wide range of line sizes and types, the Inser tValve’s wedge gate seats on the valve body, not the pipe bottom. This unique feature prevents the seat from coming into contact with the cut pipe edges to significantly extend valve life. If a repair is ever needed, it is the only valve on the market that can be repaired under pressure.

Team offers professional installation services by trained and certified techni-cians or packaged solutions ready for line cut-in. Either way, you get a valve that meets or exceeds recognized industry requirements and complies with all health and safety regulations.

Why Team’s SealTite

®

_{Completion Flanges are Better}

SealTite® _Flanges

• Team’s primary metal-to-metal seal coupled with a secondary backup O-ring seal provides greater strength and safety

• The SealTite®_{completion plug eliminates a critical leak} path that can lead to potential check valve leaks

• Packing glands are located on recessed jack bolts and can be repacked under pressure

• SealTite®_{completion flanges can be rebuilt online} allowing reutilization of all f ittings, regardless of  temperatures

Other Completion Flanges
