Feature Product: Water-Soluble Purge Film

Water-Soluble Purge Film

water-soluble purge film header

For closing welds, water-soluble Weld Purge Film offers a safer alternative to paper. Film does not contain water, unlike paper that is full of water, unsuitable for welding.

Water-Soluble Purge Film APF-PHO-06C-Fixed-Ready Water-Soluble Purge Film APF-PHO-12C-In-Use

Water-Soluble Purge Film features and benefits:
• With the new water-soluble adhesive, Weld Purge Film® produces a tough, leak tight purge containment.
• One roll can accommodate a range of pipe sizes.
• Can easily be washed away during hydrostatic testing of the pipe or just by normal wash out.
• Dissolves to molecular level leaving no traces.
• Film dams wash away completely (there are no fibers, as there are with paper products, that can clog up filters and make lumps to stick in pipes).
• Ideally suitable for welding where it is not possible to retrieve the purge dam after the joint is complete.
• For use when an Inflatable Tube and Pipe Purging System is not suitable or affordable.
• Easy to view the weld progress through the transparent material.
• Fantastic replacement to people using paper. As we know, paper has a very high percentage of water and nobody wants water vapor coming into the weld once the welding heats everything up.

Dams easily prepared with the safety knife provided.

S. Korea Completes Freeze Seal Test On 24” Pipe

Distributor in S. Korea Completes Freeze Seal Test On 24” Pipe With New Accu-Freeze® Jacket And Valve Manifold Prototype

December, 2014—GEOS Co., Ltd. is the agent in South Korea for COB Industries’ Qwik-Freezer® and Accu-Freeze® Pipe Freezing Systems, and they were contracted by a large power utility company to conduct a feasibility study with regards to performing freeze seals on large diameter steam lines. Directors from GEOS visited COB Industries in Florida to discuss this project, and COB Industries experts explained that while steam cannot be frozen there is a possibility of back-filling lines with water and creating freeze seals to isolate the lines which would accomplish the primary goal.

Following subsequent meetings in Seol, GEOS was then given the green light to contract with COB to conduct the first phase of testing by conducting a Freeze Seal Test using Accu-Freeze® equipment on a 24” Carbon Steel Pipe. GEOS and COB met once again and COB proposed a custom 24” Liquid Nitrogen Freeze Jacket with multiple LN2 inlets, a manifold prototype including multiple Accu-Freeze® solenoid valves and a custom control box containing (4) Accu-Freeze® digital controllers (see photos below). COB Industries built the equipment and shipped it to S. Korea where the test was conducted by GEOS personnel. The test was 100% successful and an ice plug was formed over a 16 hour period and then pressure was applied to pressure test the 24” ice plug to over 140 PSI.

COB Industries has been manufacturing Pipe Freezing Systems for over 45 years and their patented Accu-Freeze® equipment is used by the U.S. Navy, power plants and mechanical contractors around the world.

Multiple Freeze Plugs at Central Reference Library

PRECISION AIR CONDITIONING OF BREVARD COMPLETED MULTIPLE FREEZE PLUGS AT CENTRAL REFERENCE LIBRARY IN COCOA FLORIDA USING COB INDUSTRIES ACCU-FREEZE SYSTEM

freeze plugs

The work in the photographs was performed at the Central Reference Library in Cocoa Florida. Precision Air Conditioning of Brevard is the Prime Contractor performing a major mechanical renovation/upgrade to that facility for Brevard County.

The need to maintain temperature and humidity control is paramount as this facility contains many of the genealogic documents related to Brevard County. These particular line freezes were performed using the COB Industries Accu-Freeze System.

The work consisted of freezing (2) 6” dia. Chilled Water lines and (2) 4” dia. Hot Water lines all of which were Sch. 40 Carbon Steel Pipe. During the time six 3” butterfly valves and ten 2” ball valves were replaced downstream, which required the ice plugs to be maintained for approximately 4 hours. The line freezes and subsequent replacement of the isolation valves, will allow work on individual AHU’s in a localized manner, without shutting down the entire HVAC system.

The line freezes were utilized to prevent the need to drain/capture/re-fill approximately 1400 gallons of treated Chilled water and Hot Water, which would have been very time consuming and costly.

These are pictures of the 36″ River Water Main repair. The site uses river water for cooling water in the production units. This leak had one of three pump houses shut down. With one pump house off line units had to cut back production. Thanks to you and your company for expediting the repair plug that was ordered Friday afternoon and received and installed Tuesday morning. With the plug installed normal production operation could resume. Once again thanks, and we will call you for any future needs. Attached are pictures of the repair plug in place.

Accu-Freeze 12 inch freeze at CBC Radio-Canada

<h2>COB Industries Accu-Freeze 12 inch freeze seal</h2>

COB Industries

April 2014— Accu-Freeze was used by a mechanical contractor in Montreal to perform a freeze seal on a 12” water main in the boiler room of the CBC Building in downtown Montreal. A freeze seal, or “ice plug” was required in order to change out an old valve that was seized up without having to shut down or drain out the system. They decided to contact COB Industries in order to purchase Accu-Freeze® equipment and to receive training to prepare them to tackle a critical job of this nature. In addition, they hired COB to provide a pipe freezing specialist to be on hand as a consultant while the job was carried out. The job was scheduled for the third week in April.

COB Industries cbc3 COB Industries cbc4 COB Industries cbc5

After a one-day Accu-Freeze® training session with COB Industries, the freeze seal was performed at the CBC building. An ice plug was achieved in approximately 6 hours in spite of moderate vibration caused by a nearby pump (vibration causes turbulence in the water inside the pipe which impedes the freezing process). Once the presence of ice plug was confirmed the old valve was disassembled and removed and the new valve was hoisted into position and attached. The valve replacement took approximately 2 hours and the ice plug was maintained throughout the process. Once the new valve was in place, the Accu-Freeze® equipment was removed, and within 2 – 3 hours the plug had thawed and the system was fully operational again.

COB Helps Develop Revolutionary Pipe Purging Technology

COB Helps Develop Revolutionary Pipe Purging Technology PurgeGate Valve

November, 2013—COB Industries introduced revolutionary new PurgeGate technology which is certain to be a game-changer in the world of pipe purging. Tandem inflatable pipe purging systems have proven to be the fastest, most effective method of pipe purging when welding stainless steel, chrome, titanium and other materials that require an oxygen free weld, but the potential risk of bursting the dams due to over-inflation has always been an issue…until now.

COB Industries, working together with Huntingdon Fusion Techniques of the U.K. has introduced PurgeGate valves which are proprietary devices that function like an in-line regulator or pressure reducer that prevents the bladders from over-inflating no matter what pressure or flow rate is used. ANY other type of inflatable purge dam can be ruined if the gas flow / pressure is turned up too high or if the purge valves are not set or maintained properly. The new Argweld® QuickPurge® II systems with PurgeGate are the ONLY true plug-and-play purge system with no valves to adjust or maintain, and no risk of bursting bladders due to over-inflation.

The benefits of inflatable purge dams (faster purge times, less gas consumption, etc.) have been well established and now those benefits can be utilized with a longer lasting, more durable system. To see how quickly these systems pay for themselves (ROI) click here.

Qwik-Freezer Used For Repairs At Etihad Tower In Abu Dhabi

Qwik-Freezer Used For Repairs At Etihad Towers In Abu Dhabi

July, 2013—Contractors at the world-famous Etihad Towers in Abu Dhabi (pictured above) used Qwik-Freezer® Pipe Freezing Systems to successfully perform multiple freeze seals for piping repairs on the 39th level of Tower 4.

Freeze-Sealing (also referred to as “pipe freezing” or “ice-plugging”) is a process that involves freezing the contents of a pipe to create an internal ice plug to isolate sections of pipe for repair and maintenance, valve replacements, etc. This process eliminates the need to drain long sections of pipe and reduces down time for repairs. Freeze-Sealing was first used by the US Navy in the 1940’s and is now a common practice in building maintenance and countless application in the piping industries.

Qwik-Freezer® Pipe Freezing Kits utilize liquid CO2 to create ice plugs for freeze sealing of up to 8” pipe and are probably the most widely used system around the world. Qwik-Freezer® equipment has been manufactured by COB Industries, Inc. in Melbourne, Florida for over 40 years.
