1. API 6D -24^th Edition Certification:
   Why it’s Important for Quality and Safety of Your Check Valves

   December 16, 2016 6:51 pm Comments Off on API 6D -24^th Edition Certification:
   Why it’s Important for Quality and Safety of Your Check Valves

   What is the API Q1 ninth edition and API 6D 24^th edition monogram specification?

   The American Petroleum Institute (API) is a trade association that has led the development of petroleum and petrochemical equipment and operating standards. Its API Monogram Program verifies that manufacturers are operating in compliance with industry standards.

   The API Q1 ninth edition specification establishes the API Quality Management System requirements necessary for organizations to consistently and reliably manufacture products in accordance with API or other specifications for the use in the petroleum and natural gas industry.

   The API 6D 24^th edition specification defines the requirements for the design, manufacturing, assembly, testing, and documentation of valves for application in pipeline and piping systems for the petroleum and natural gas industries.

   This API 6D 24^th edition specification holds hydrostatic and pneumatic testing to a new higher standard, unlike the less API 598 testing, API 6D testing requires increased pressure testing durations, test medium rust inhibitor injection, medium pH monitoring  and more stringent design and manufacturing process control, as well as packaging requirements to reduce valve damage from transportation.

   When requested by the purchaser, an API 6D monogram valve manufacturer must meet the strict testing and documentation requirements to insure the valves performance under designed operational pressure and temperature conditions.

   Purchasing valves under the specification ensures greater reliability and safety for equipment and personnel.

   Common Industries that Require API 6D

   When transmitting raw materials and potentially harmful chemicals, it is critical that check valves are tested for proper safety and functionality. Therefore, the API 6D certification is commonly required for valves used in petroleum, natural gas and electrical generation industries. Specific industries requiring API 6D include:

   • Natural Gas Transmission: Check valves are frequently built into natural gas transmission pipelines to prevent the occurrence of reverse flow. They act as critical components within these systems, as improper flow could result in dangerous leakages, contamination, explosions, or fires.

   • Petroleum Production and Refining: Transforming crude oil into refined products for consumer industries requires a multi-step chemical process that adheres to strict standards. Check valves are used in a range of petroleum-related applications, including discharge compressors, cooling towers, water treatment, pumps, generators, and boilers.

   DFT Valves Built to API 6D 24^th Edition Standards

   In order to meet the needs of our clients in the natural gas and petroleum industries, we have certified our GLC® and PDC® check valve manufacturing processes to meet API 6D 24^th Ed. specifications. By improving design, manufacture, assembly, testing, and documentation processes, we’re able to provide a higher level of quality and safety.

   • GLC® Silent Check Valve: This silent center-guided, spring-assisted flange valve can be used with several types of fluids and can operate under a wide range of temperature and pressure combinations. This check valve is API 6D 24^th certified and available in various materials and sizes.

   • PDC® Check Valve: A silent, non-slam valve that is specifically designed to allow gases to flow in one direction through a pulse-dampening chamber on the discharge side of a compressor. Our PDC® model is API 6D 24^th certified and available in a range of materials and sizes.

   • DFT is in the process of adding other valve models to the list of API 6D 24^th certified valves. Contact DFT if you require API 6D 24^th Edition Certification.

2. Valve Tips for Fall Shutdowns

   September 8, 2016 6:54 pm 1 Comment

   Fall shutdown season is upon us.

   Once a year, generally in September, manufacturers spanning every industrial sector — from metal stampers to power plants — shut down for anywhere between 1 to 3 weeks. As you well know, these fall shutdowns are not company-wide vacations; instead, they allow facilities to perform the important cleaning, repairs, maintenance, component or system replacements, and facility inspections required to keep your plant running smoothly at peak efficiency for another year.

   In preparation for your fall shutdown, you should be working with a valve manufacturer to ensure that all of your valves are functioning properly or, when they are not, to repair or replace them. Fall shutdown is the ideal time to do so.

   Common Valve Repair Problems

   Valves are an important aspect of many industrial processes but there are perhaps no facilities more dependent on their proper functioning than power plants. Manufacturing facilities and power plants alike tend to run across three problems when attempting to repair their valves.

   Many facilities, particularly older ones that have not had a full overhaul in a number of years, have older valves. Plant and maintenance managers often prefer to repair these valves rather than replace them. Often, however, they will find that the original valve manufacturer is no longer in business and that the required valve repair kits are no longer available.

   The second common problem is that, even when they are repairable, a facility’s valves may be so old that they have become obsolete. Valve technology and manufacturing is constantly improving — there is a high chance that your old valves introduce a potentially costly inefficiency that, though unavoidable at the time of installation, has been corrected by newer valve technology.

   Finally, many plant and maintenance managers find that the cost of repairing older valves and fitting them with replacement parts can be prohibitively expensive. This can be particularly true in facilities that deal of condensate, such as power plants.

   DFT® Inc. and Fall Shutdowns

   With more than 70 years of valve manufacturing experience, DFT® Inc. is a leading control and check valve manufacturer.

   Prior to shutdowns, DFT can work with your planners and maintenance team to provide education on the new valve technologies available for your facility. DFT is available to evaluate your valves and your piping system as a whole, to help reduce turbulence and potential failure. Our team can help guide you through the process. Our experts will help you to determine whether cleaning and repair is a viable option, or if you should consider replacing your valves with newer valve technologies.

   If you determine that replacement is the better option for you, we will provide those replacements for you within the timeframe of your shutdown. Typically we replace failing swing and double door check valves with a newer technology provided by spring assisted, silent check valves.

   Learn More

   From the world renowned DFT® Silent Check Valves to the innovative DFT® HI-100™ Control Valves, DFT®’s team of valve experts has experience providing recommendations to a variety of industries. Industries served include power generation, petroleum production & refining, building maintenance, chemical processing, water treatment, food & beverage, and more.

   Facilities with steam applications, namely power plants, often experience high levels of condensation which, when not managed properly can cause any number of problems — rust and scale, lubrication degradation, reduced performance, and even machinery failure, to name a few.

   We strongly encourage our power plant clients to consider the SCV® valve 3” and smaller for condensate and steam applications. Learn more about the SCV® valve by downloading the spec sheet.

   Our larger diameter flanged and wafer style valves are available in sizes through 36” and larger pressure classes ranging from 125#-2500#.
