COB Industries Introduces V-Block For Small Diameter LN2 Pipe Freezing

June, 2013—COB Industries, the manufacturer of Qwik-Freeze® and Accu-Freeze® Pipe Freezing Systems for over 40 years, has just introduced the Accu-Freeze® V-Block which is an ingenious new pipe freezing tool designed for LN2 freezes on tube and pipe sizes from 1/4” to 1-1/4” diameter.

The patented Accu-Freeze® technology has been used extensively at several of the U.S. Navy’s prominent shipyards and on Nuclear Submarines for years and COB was approached about developing a faster, easier method of freezing small diameter pipe on Nuclear Subs and the new V-Block was the result.

The V-Block is an amazingly simple and effective LN2 delivery system that can be used on various sizes of pipe.

The precision-machined stainless steel “block” is simply strapped onto the pipe and incorporates standard NPT fittings for LN2 intake and exhaust with a self-contained port to accommodate a thermocouple for reading the temperature of the pipe wall.

The V-Block can be used in conjunction with an Accu-Freeze® system (where the LN2 injections are automated and the temperature of the pipe wall is controlled with a programmed set-point) or it can just be used with standard LN2 tanks and cryogenic hoses.

The liquid nitrogen is pumped into the intake and circulated through the V-Block and vents from the exhaust, without coming in direct contact with the pipe. One of the key benefits of the V-Block design is that there is almost no set-up time required and it provides a freeze seal in the fastest manner possible.

It is also extremely cost-effective with a list price of just over $800.00 each.

Accu-Jacket – COB Industries New Line of Accu-Freeze™ LN2 Freeze Jackets

March 2013 — COB Industries now manufactures Accu-Jacket Freeze Seal Jackets (“clam-shell” style) in addition to the standard Accu-Freeze™ kits. These Accu-Jackets are popular with customers that need to do repeated freezes on the same size or sizes of pipe. The amount of set-up time is greatly reduced with Accu-Jacket Freeze Seal Jackets that are manufactured to fit specific pipe sizes and are just bolted around the outside of the pipe. The Accu-Jacket freeze seal jackets have injection ports built in which connect to the LN2 feed and exhaust ports to vent the gas to atmosphere. They are constructed of high-grade aluminum with a double-wall design that creates an insulating air gap between the liquid nitrogen and the ambient air outside the jackets. Accu-Freeze™ Seal Jackets are available for any size pipe.

COB Industries Awarded Large Contract for Subsea Plugs

January 2013—COB Industries was contacted by Swiber, an offshore construction services company, to discuss their need for subsea plugs for a large offshore oil project in Brunei. COB Industries has been building various types of high-tech pipe plugs for offshore applications for years including large Seachest Plugs, ROV-Operable Plugs and plugs for various pressure applications and long-term abandonment projects. COB has supplied subsea plugs to Shell Pipelines, BP, Chevron, Exxon, Petrobras, PetroTrin to name a few.

Swiber needed multiple J-Tube subsea Plugs for their rig. J-Tubes are vertical sections of pipe that are used to connect offshore production piping to seabed pipelines. The J-Tubes (shaped like the letter “J”) are actually guides or mandrels for the subsea pipeline which is pulled up through the J-Tubes. This method is commonly used and eliminates the need to make underwater connections between the riser pipes and seabed pipelines.

After researching several other options and then having discussions with COB’s engineering and design team, Swiber came to the conclusion that they wanted COB to supply the subsea plugs that they needed at their offshore project in Brunei. Swiber ordered a total of 42 plugs for 10” – 12” pipe, and the complete order was shipped and delivered on schedule and are in service at this time.

Qwik Freezer® Multi Freeze Control Station

QF 910 Multi-Freeze Control Station

QF 701 Remote Actuated Valve

COB Industries, Inc is proud to announce a new remote operated Qwik Freezer® liquid CO2 pipe freezing system. With 30 plus years of pipe freezing experience, industry is constantly coming to COB to help with new challenges facing its piping maintenance issues. The US Navy has used pipe freezing for years, and in their nuclear powered vessels the Qwik Freezer® liquid CO2 system has been the primary choice. Many times when valve maintenance comes up in nuclear powered vessels it entails doing multiple freezes at one time. This can mean difficult setup and extended exposure to radioactivity for the freeze team. The Navy came to COB with a request to design a system that would allow them to remotely operate the liquid CO2 supply for multiple freezes from a single control station.

To answer this, COB Industries introduces the QF 701 Remote Actuated Valve and the QF 910 Multi-Freeze Control Station. The QF 701 is a high pressure cryogenic solenoid valve with a manually actuated backup system (in case of a power failure). The remote valve is mounted on the CO2 bottle and is connected to the QF 910 via a 100 ft extension cord (QF 711). High pressure CO2 hoses pipe the liquid CO2 into the freeze jacket or collar. The QF910 is a remote six-jack freeze control station which allows the operator to inject liquid CO2 into the freeze area with the single push of a button while staying away from potentially hazardous areas. Prior to the development of these systems, normally the operator had to enter the reactor compartment to manually operate the valves, thus increasing his/her exposure. The push button energizing of the Remote Actuated Valve allows the operator to inject CO2 as needed by simply holding the button down for longer or shorter periods of time depending on the requirements of the application. Remote temperature monitors are used to let the operator know when more CO2 is required. This also greatly conserves liquid CO2 by only putting in the proper amount required to maintain the ice plug.

New Purge Monitor, Tungsten Grinder at Fabtech / AWS Show

October 2010—COB Industries is preparing for the upcoming Fabtech / AWS Trade Show which will be in Atlanta from November 2 – 4, 2010 at the Georgia World Congress Center, and is planning to unveil 2 exciting new products in the welding industry.

1. The new Critical Weld Purge Monitor is bound to generate a lot of excitement as the latest addition to the Argweld® line of purge monitors. This highly accurate monitor is designed to monitor oxygen levels down to 10 Parts Per Million (PPM) during the welding of titanium and ultra-pure stainless steel applications to prevent discoloring or adverse effects on the weld caused by oxygen. This unit is similar to the Argweld® Titanium Weld Purge Monitor with a few added features including an automatic pump for extracting a continuous gas sample where it is not possible to deliver a constant flow to the sensor.

2. The New TEG-III EXT Grinder is an improved model of the popular TEG-III Tungsten Electrode Grinder which now offers a vacuum dust extraction system to extract all of the dust from the electrodes which in many cases is carcinogenic. The TEG-III EXT is equipped with the most powerful motor of its kind with a lifetime warranty.

COB Industries’ exhibit booth (#7632) has also received a makeover with all-new graphics, photos and displays and will be located in the welding section of the show in the North Hall of the World Congress Center.
