 Everything You Need To Know About Flange Facing and its Benefits

When it comes to the maintenance of flange surfaces, Flange Facing seems to be a perfect solution. With a proper, timely, and maintained repair of flanges, you can help avoid major issues such as corrosion and leakages. This beneficiary service makes sure that the old flanges continue maintaining joint integrity between them.

Why There is a Need for Flange Facing?

A flange is constantly exposed to continuous wear and tear and is likely to damage due to impacts and turbulent flow along with other impactful components such as installation, construction, or cuts from the gaskets leak. With the help of flange facing, you can surface the flanges in a way that provides them a spiral grooved finish. 



This type of finishing allows the flanges to be less prone to any potential leakages such as the liquids and gases are forced to travel through a long and spiral path rather than going straight across the flange face. That’s also the exact reason why flange facings are considered to be one of the most significant repair jobs during maintenance and plant shutdowns. 

Which Industry Requires Flange Facing Majorly?

There are several large-scale industries such as petrochemicals, oil and gas, pipeline, pharmaceutical production, and power generation that require flange facing services more than any other industry in the sector.

Internal and Outside Diameter in Mounting – What’s The Difference?

There are two major ways to mount flange facing machines namely ID and OD mounting. In the internal diameter mounting, the clamp legs found inside of the machine are placed properly inside the flange. On the other hand, outside diameter mounting requires the clamp legs to be pushed inside the machine while being externally mounted around the flange.

Applications of Flange Facing – Where is it used?

There are several tasks that can be accomplished with flange facing services. Here’s a quick rundown of several applications of flange facing:

●        Repairing nozzle flanges of heat exchangers

●        Repairing phonographic finish and flat face raised flanges

●        Refacing sealing surfaces of ship hatches

●        Mounting ship thruster, milling, and drilling

●        Resurfacing housings based on large pumps

●        Boiler feeding pump flanges

●        Refacing the main inlets of steam flanges

●        Weld preparing, sealing, beveling, and facing of the pipe

●        Repairing piston rod mating flanges

●        Rematching the bearing surfaces of rotary cranes

●        Milling flanges wind tower section

●        Plate and vessel weld preparation

●        Repairing ring grooves and cutting new grooves

●        Rematching the tube sheets with gasket seals

And there’s even a lot more to add to the list. Flange facing services are certainly one of the most important aspects of the industry.

What Range Can You Find Easily?

Based on the skillset of a company, you can find several providers offering portable and highly-durable flange facers that may vary from 0 inches to 60 inches for internal and outer diameters surface mounting. There are some specialized companies that may offer ranges up to 120 inches. A lot of companies also provide tools that have the capability to bevel, square, reface, mill, machine, or counterbore prep or seal ring profiles. Moreover, it also adds up even more to its versatility and helps in converting the single point to milling operations.

Do You Need To Buy or Rent?

Whether you need to buy or rent a tool depends on two major factors. First of all, if you have a regular need of servicing your flanges more often than other industries, buying a tool instead of renting sounds like a more economical solution. Moreover, if you need to deal with different sizes of flanges, you might need to purchase different tools based on different properties to service varying flanges, you will find renting a better solution than buying your own tools. Therefore, you need to constantly analyze the requirements and constraints to determine whether you should buy your own tools or rent them.

The Takeaway

In no doubt, flange facing is a very important service in the industry. As the flanges have to face regular wear and tear, you need to make sure that you’re doing proper maintenance for them. This will allow you to make sure that your flanges last for a longer time.

Hydraulic Bolt Tensioner: How It Works

Image
  For simpler and more accurate tightening of large-diameter stud and bolt assemblies, hydraulic bolt tensioners are mechanical fasteners that are utilized in place of normal bolts or hex nuts. Several bolt tensioners use manual or hydraulic techniques to apply torque. Devices that use hydraulics employ fluid force. Products that require manual power are turned using a hand tool such as a torque wrench . There are also hydraulic bolt tensioners that impart torque using different non-manual, non-hydraulic techniques. The greatest amount of rotating force that can be generated for all varieties of bolt tensioners is indicated by the torque rating. Thrust collar inner diameter and threaded diameter are additional crucial characteristics. To discover more about how hydraulic bolt tensioners operate, read the entire article. How does it work?  Large diameter bolts can be accurately and quickly tightened to high preloads using a hydraulic bolt tensioner . Like hydraulic torque wren...

All about Flange Facing and Its Advantages

Image
  When there is a pipeline or pipework, you will see flanges or welded joints made up of distinctive designs, sizes, and materials. A flange can be described as an internal or external ridge or a lip/rim that is carried out for strength. There can be an iron beam in the form of a T-beam or I-beam. There can also be a flange of an attachment to a different object such as a steam cylinder or on the ends of a pipeline etc. There is a lot of evidence that shows that in various pipeline systems, both flanges and valves can release hydrocarbons, and the piping ends up becoming the biggest contributor. Hence, a good flange-facing process and regular inspection can be a great solution to this problem.  Importance of Flange Protection When discussing the utility, oil, and gas industry, thread protection and pipe flange are two of the most important things. There is an issue of contamination when we talk about these industries. This contamination not only happens after or during the sto...
