Committed to continuous improvement and production of quality products for optimum performance and reliability, Forum Drill Pipe Float Valves have become an industry standard with their superior engineering, quality, construction and dependability in service. FORUM manufactures a complete line of Float Valves, Repair Kits, and Puller Assemblies to accommodate a wide range of drilling situations and operating conditions, including H2S and Steam Service. These Drill Pipe Float Valves provide added blowout protection at the bottom of the drillstring, prevent flowback when joints are added, and keep cuttings out of the drillpipe to prevent bit plugging while making connections. Note: It is recommended that if multiple Drill Pipe Float Valves are run in the same string, they be separated. However the Model GS may be stacked. QUALITY CONSTRUCTION FORUM Drill Pipe Float Valves have been designed, manufactured, tested, and validated in accordance with accepted engineering, manufacturing, and quality assurance standards. RATED OPERATING PRESSURE Model F Drill Pipe Float Valves rated 7,500 WP. Model G & GS Drill Pipe Float Valves rated 7,500 WP. CAGES & GS Cage construction of the various Models F and G includes ductile iron, and there is an option for low alloy steel cage in some Model F sizes. Hardness levels of these are at or below 22 Rockwell C to resist hydrogen sulfide stress cracking when used for H2S applications. The Model GS cage is made from low alloy steel. Stainless Steel available upon request. SPRINGS Models F and G utilize high alloy springs for all applications.

This application requires a short length and high fluid velocity. The FS and FSA Float Valve is only 6 inches long and has carbonized surface treatment. The side seal is an O-Ring with back-up rings which allows for a 7500psi pressure rating. See the chart on page 8 for dimensional information.

It is identical 2 to the Model G except the spring has been removed and the beveled design of the guide greatly reduces the danger of hanging up on the float valve when retrieving tools below it. 3 4 SPECIAL INSTALLATION The Drill Pipe Float Valve is installed near the top of the drillstring. Escaping air is channeled under the flapper valve, forcing it closed, and preventing loss of pressure. 5 Note: In order to lose as little air as possible from the drillstring when a joint is made up, it is recommended that the float valve be moved up in the drillstring each time a new bit is installed. Caution must be exercised, however, to keep, the valve at least 6 one joint below the kelly; otherwise, the valve could be blown out of the drillpipe by trapped pressure when the kelly is removed.

The ribs are made of 5-16" steel plate. They are formed to the proper shape on a large forming press.

  • Tridium's Sedona 1.2 Component Descriptions
    Tridium’s Sedona 1.2 Component Descriptions Components are deployed in kits which are available from Tridium, Contemporary Controls and other members of the Sedona community. Kits without a company name are from Tridium. Kits with a company name and no product name are from a Sedona community member and these components can be used with other Sedona devices. Kits with both a company name and product name are hardware dependent thereby limiting portability. What follows are component descriptions of Tridium-release kits compliant with Sedona release 1.2.28. In prior releases by Tridium, Tridium put all the Sedona components into one kit called the Control kit. With this final release, Tridium organized these components into multiple kits with more meaningful kit names. This organizational structure has been maintained in this document with components listed by the newer kit names. It is recommended that these kits or components not be modified from their original form to ensure the portability of components and kits among members of the Sedona community. If changes or enhancements need to be made by a Sedona developer, the developer can use what currently exists, modify or enhance the component, but then save the result as a custom component using the developer’s name. The developer would then create a kit name that also includes the developer’s name making it clear it is a custom kit. When studying these components keep the following in mind. Boolean variables are assumed if there is a false/true state indication. Integers (32-bit signed integers) are shown as whole numbers while floats (32-bit floating point) are shown with a decimal point.

SIMMONS, logging specialist NORTHEASTERN FOREST EXPERIMENT STATION FOREST SERVICE UNITED STATES GOVERNMENT PRINTING OFFICE - - - WASHINGTON, D. C, 1951 For sale by the Superintendent of Documents, Washington, D. C. Price 75 cents Preface THOSE who want to be successful in any line of work or business must learn the tricks of the trade one way or another. For most occupations there is a wealth of published information that explains how the job can best be done without taking too many knocks in the hard school of experience. For logging, however, there has been no ade- quate source of information that could be understood and used by the man who actually does the work in the woods. This NORTHEASTERN LOGGERS' HANDBOOK brings to- gether what the young or inexperienced woodsman needs to know about the care and use of logging tools and about the best of the old and new devices and techniques for logging under the conditions existing in the northeastern part of the United States. Emphasis has been given to the matter of workers' safety because the accident rate in logging is much higher than it should be. Sections of the handbook have previously been circulated in a pre- liminary edition. Scores of suggestions have been made to the author by logging operators, equipment manufacturers, and professional forest- ers.

  • Online Trowel Fitting Guide the Wagman Online Fitting Guide Will Help You Easily See All of the Trowel Blades and Pans That Fit Your Machine
    Online Trowel Fitting Guide The Wagman online fitting guide will help you easily see all of the trowel blades and pans that fit your machine. Choose the make and model of your equipment for a list of what fits your trowel. Visit www.WagmanMetal.com for the interactive fitting guide. 50 Years of Excellence Since 1963 Wagman Metal Products, Inc., has been a leading supplier of power trowel replacement blades and floating pans in the concrete industry. We want to thank our dealers and customers for their continued support, helping to make Wagman Metal Products successful. We are truly a family business that started when my grandfather George F. Wagman, Sr., and my father George F. Wagman, Jr., began production and distribution of a variety of blades to fit many brands of power trowels. Today, Wagman manufactures over 350 different blades to fit the trowels of over 40 companies. In 1980 I started working on our factory floor, performing a variety of jobs in order to learn all the aspects of the manufacturing process. My experience over the years helps ensure that all the products we manufacture meet my tough standards for quality and value. If it's got my name on it, you know you can count on it! Wagman's experience and innovation have helped pioneer the development of heavy-duty blades to cope with the stresses of the new generation of heavy riding trowels. More recently Wagman has perfected the design of the plastic trowel blade, engineered to provide burnish free finishing and unparalleled blade life. Be sure to check out our newest innovation, the Revolution Rotary System.
