Just a friendly reminder…here at Texas Flange we try to make the flange requisition and purchase experience as seamless as possible for our customers. This includes providing commodity stock pieces by the bulk load, as well as creating custom flange pieces for unique applications. Regardless of the scope of your flange inquiry, our sales and technical support staff is trained to provide you with whatever you need, even if your assigned sales member is out of the office.
All emails are monitored and answered when any individual is out of the office, so that you don’t need to hunt down a different email address in order to get your questions answered and your orders processed. Just send in your inquiry for flanges as you normally would, and we will answer back from the email address of the same representative you are familiar with. This allows your flange sales rep to review the correspondence from their own email archives when they return and gives them the ability to ensure all requirements are communicated clearly to every member of the production team.
All flange orders are digitally archived in a manner that allows for sales and support staff to make the necessary notations up through and beyond the shipping and invoicing process and as a result, all sales staff should be able to address any concerns you may have regarding your flange order.
Always remember that we at Texas Flange are working hard with our production team to review your request and provide accurate pricing and lead time as necessary.
Ring type joint flange face surfaces are increasingly popular options with regards to flange connections, and offer a good alternative to the standard raised face in specific applications. Typically, these alternate facings are utilized in higher pressure and temperature service projects, and help to provide a more effective sealing solution to media critical pipeline and pressure vessel infrastructure. Although only an option in ANSI/ASME class flanges, they are required as the standard surface sealing in API specification flanges. This is due to the fact that API flanges typically operate at a higher pressure in comparison to their ANSI/ASME flange counterparts.
The seal of a ring type joint gasket is meant to occur under the torque and force of closing the bolt and hardware after mating one flange to another. Typically, ring type joint gaskets are made of softer material than the actual metal of the flanges they are sealing. The most common of these materials is a soft iron which are used both in API and ASME/ANSI flange connections. Applying a slow and steady pressure of tightening on the hardware of the flange causes the gasket to get “crushed” within the ring joint surface, and this helps to prevent any type of media leakage during operation of the flange assembly.
These gaskets are designated by an “R” number, of which the dimensional data, and the corresponding nominal and pressure class flange, are available on our website. R gaskets are available in oval and octagonal configuration. Given the smooth sealing surfaces of ring joint faces as designated by ASME B16.20, both configurations work well, and are not typically noted in purchase as they are virtually interchangeable.
Bottom line – when in doubt, higher pressure and temperature applications typically call for ring joint facings given their reliability and usefulness when optimal surface sealing is necessary. Give us a call to help you with your ring joint flanges, or let us know if an alternate flange facing is an option.
We have received several inquiries over the years for nozzle type flanges, commonly referred to as “long weld necks.” These types of flanges and the different varieties in which they are offered are meant to replace pipe, not weld up to it, and as such we would like to clarify for everyone in the industry that these items do not have schedule bores. A typical weld neck flange has a weld prep at the tip of the neck to weld up to matching pipe, whereas long weld neck flanges, or “nozzles,” are square cut at the ends for the purpose of utilization with your tank or alternate assembly. As such, many inquiries which we receive include schedule bores that we eliminate in our quote reply to our customers, as these schedules are not applicable.
Our nozzle flanges are available in the more common lengths of 9”, 12”, and 16”, as well as any larger or smaller overall lengths to suit your needs. Typically, the larger the nominal size and pressure class flange, the larger the overall length requested. However, this is entirely subjective and at the discretion of the customer. Contrary to popular suggestion, there is no universal “standard” length because these parts are made in accordance with the application necessary. We offer a variety of barrel sizes, from the more familiar long weld necks, heavy barrels, and equal barrels. We also provide intermediate barrel products depending on your needs. As most regular weld neck flanges, these nozzles are typically made from forged carbon steel and stainless steel grades, though we do get the occasional request for chrome alloy and nickel alloy nozzle flanges. Feel free to submit your own technical drawing for quotation to our sales department and we would be happy to help get you the flanges you need.
