How to Order Custom Flanges?

A flange industry must focus on specific flanges like ASME, ANSI, AWWA, and industry-standard flanges that specialize in customer order flanges. With a wide range of systems, shops, and industries dependent upon high-performance flanges, custom pipe flanges are essential to get the job done correctly. Modified and custom flanges for specialty projects may offer the performance expectations, inspection requirements, same quality. They may also offer material, specific sizes, or fit for a unique application.

How does custom flange ordering work?

Job shops specialize in custom work that often requires large quantities of raw material ready to be crafted in the shape, style, and size of flange a customer requires. It includes modification on industry-standard flanges or unique shapes like:

  • Reduced flanges
  • Flanges with spools between custom layers
  • Flanges with dual bolt patterns
  • Square pipe flanges

How to order a custom flange

The first step to order a custom flange is to gather as much information as possible about the flange you need. It includes details like:

  • Flanges you need
  • Material grade
  • Project requirements: Specification, pipe size, connection type, facing, pressure class

Common flange specifications and standards

Custom forgings and special flanges and fittings can be designed to meet any number of unique standards and specifications. Some common classifications for custom pipe flanges include:

  • Metric system flanges
  •  Large industry standard
  • Tube turns
  • CL 123 Lightweight
  • ANSI
  • ASME, and
  • AWWA

Custom flange types

Regardless of the custom specifications or size, the fundamental design of most flanges falls under 6 common styles created to support, cover, connect or close pipes and pipe systems.

The flange types include:

  •  Socket-weld flanges
  • Threaded flanges
  • Lap joint flanges
  • Blind flanges
  • Weld neck flanges
  • Slip-on flanges

Performance and material grades

Custom pipe flanges need to manufacture from a wide variety of material grades and materials. Carbon steel is one of the popular solutions, as are specialty alloys and stainless steel, depending on the industry. Forged and plate are also common, as are aluminum and titanium for lightweight jobs.

Importance of AWWA Flanges in Piping Systems

Image
AWWA flanges, also known as American Water Works Association flanges, play a very important function in piping systems used for water supply and treatment. These specialized flanges are designed to meet the high quality standards and requirements set by the American Water Works Association, that ensure the safety and reliable conveyance of water in municipal, industrial, and commercial applications. The importance of  AWWA flanges  lies in their ability to provide secure connections between pipes, valves, pumps, and other components, preventing leaks and ensuring the integrity of the water distribution network. By following and meeting the strictly established manufacturing standards and quality control measures, AWWA flanges help maintain the safety, efficiency, as well as sustainability of water supply networks, which helps in protecting or safeguarding public health, environmental protection, and economic development. 8 key points to understanding the importance of AWWA Fla...

Stepping Into Flanges

Image
  The flange is one of the essential components required to connect two pipes. It helps in connecting the ends of two pipes through welding or threading. Flanges are classified into two main categories as per the attended modes: welded and  threaded flanges .  When you want to connect two pipes, you’ll need a pair of flanges, a gasket, and several nuts and bolts to complete the flange joint. First, put the gasket between the two sealing faces and then tighten the bolt. When the gasket surface pressure reaches a certain level, it deforms to fill the uneven parts of the sealing surface to achieve the perfect leak tightness. A flange joint   is usually a detachable link. It means the detachable components are divided into tube flanges and containers. If we look from the perspective of structure types, they are threaded, loose, and integral flanges. Butt and flat  welding flanges  are two general types of integral flanges. Flat welding flanges are applicabl...

5 Common Valve Types Every Oil and Gas Engineer Should Know About

Image
A valve is a mechanical device in a piping system used to control the flow and pressure of contents – liquid, oil, vapors, or gas. Here is a list of 5  standard valves that every oil and gas engineer should know: #1. Ball valves It's a rotary motion quarter-turn valve. It uses a ball-shaped disk to control the flow of components flowing in the piping system. When you open the valve, the ball's holes come in line with the body inlet, allowing contents to pass. The ball valves can withstand a temperature between - 200 deg C and as high as 500 deg C. the best thing about this valve is that it’s a quick-acting type. Some of the different types of ball valves include: ·           Floating ·          Trunnion Mounted ·          3 Way ·          Top entry ·          Side en...
