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.

A Note on Stub Ends

Displaying stub end.pngflanges, flange, ansi, pipe, fittings, awwa, carbon, blind, petrochemical, industrial, waterworks, stainless, steel, asme, api, weld, forgings, orifice, slip, industrial flange, industrial flanges

 

There are two standards to which Texas Flange offers a variety of stub ends to accompany our flanges. The MSS standard is the regular length stub end and the most commonly used in the flange industry. The ASA type stub end is of a longer length and is less common than the MSS type, though it may be more suitable for your application.

 

 

MSS Type A stub ends are the industry norm and are utilized with standard flat face lap joint flanges. The lap thickness of the stub end typically meets the thickness of the schedule pipe it accompanies, and the exterior of the base has a curved machine radius for the lap joint flange to mate flush over the stub end. There are many instances in which lead time is critical and of more importance than adherence to existing ANSI / ASME flange specifications, and as such our customers will often choose to purchase a slip on flange and have the face machined to meet the radius requirement of the corresponding stub end piece. Furthermore, a standard lap joint flange will typically have a longer hub length in comparison to a slip on flange, but this is often considered unnecessary for many applications. Fabricators and field workers alike often choose to go this route in the event that a lap joint in a particular size or material grade is unavailable.

 

 

Texas Flange can provide custom stub ends to suit your application, provided we are given a technical drawing with dimensions of the necessary requirements. This is sometimes an option for when fabricators choose to utilize custom lap joint or mounting flanges to fit their application.

Ring joint connections

octagonal ring joint gaskets

 

 

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.

Flanges: Nozzles / Long Weld Necks – What you need to know

flanges, flange, ansi, pipe, fittings, awwa, carbon, blind, petrochemical, industrial, waterworks, stainless, steel, asme, api, weld, forgings, orifice, slip, industrial flange, industrial flanges

 

 

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.

Conflict Minerals

Conflict-Minerals.jpg

 

 

It is Texas Flange's policy to provide customers with ethically procured products and to engage only in responsible procurement practices. Flanges, fittings, and other items supplied to our customers via our own production lines, as well as those of import flange sourcing, are from authorized raw materials. Certain minerals (tin, tantalum, tungsten and gold) produced in conflict-ridden nations, and distributed via supply chains might be used to fund armed forces engaged in illicit activities involving human-rights violations, acts of violence, etc., and consequently such materials are referred to as “Conflict Minerals”. The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 requires companies registered with the SEC to disclose whether the products they manufacture or contract to manufacture contain “Conflict Minerals” that are “necessary to the functionality or production” of those products. Texas Flange does not provide any products, components or other flange materials that contain Conflict Minerals and we are committed to customer service and ensuring that our customers meet their sourcing requirements and obligations. Our flanges are meant to comply with all applicable specs.

 

 

 

To that end, Texas Flange has exercised due diligence to determine the country of origin and manufacture of items supply chain that are of import origin, and this is done in accordance with the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and similarly recognized international guidelines. It is our policy that raw material is sourced from smelters that have been determined to be conflict-free smelters or determined to be conflict-free under other trusted traceability projects. We are happy to continue to fill out forms for our customers to ensure that we do not provide flanges and fittings from conflict sources, but let this note serve as a disclaimer that it would not be necessary. We are committed to quality and satisfaction in the flange and fitting industry and look forward to a strong relationship with all of our customers.
