How to Install a Weldo Flange?

Installing a Weldo Flange requires a few simple steps. Before you begin, make sure the surfaces to be mated are clean and free of debris or foreign materials. Using a spotfacer, ensure the mating surfaces are properly aligned, and that the flange is properly centered on the surface. Place an appropriate gasket between the two surfaces and position the flange bolts in their designated location. When all preparations are complete, tighten each bolt to draw the two sides firmly together by using a torque wrench.

What Size and Type Should I Use?

Choosing the right size and type of Weldo Flange depends mostly on where it is being installed and what kind of connection that needs to be made. Generally speaking, most weldo flanges come in standard sizes, but it is important to check the specifications for the project you are working on to ensure that you have the correct measurements. Additionally, there are various types of flanges available depending on your purposes. Some materials work better than others depending on temperature, pressure, and corrosion resistance levels. Make sure you understand what kind of flange will work best for your particular application before beginning installation.

How Do I Inspect the Connections for Leaks?

Once your weldo flange has been properly installed, you will need to inspect the connection for any potential leaks. Leakage can introduce contaminants into the system and cause it to fail prematurely, so it is important to do this step carefully. Start by using a hand held bubble level to ensure that each side of the connection is even and level. Then use a leak detection fluid or gooseneck hose to check for airtightness. Finally, if you need to, you can use a pressure gauge or test kit to quantify how much pressure your connection is holding compared to its rated value.

Weldo flange specifications 

The Weldo flange is a type of industrial pipework fitting used to join two sections of pipe. It is made from alloy steel, and its specifications include an inner diameter of 0.625 inches (1.59 cm), a surface finish of no less than 32 micro-inches RMS and a pressure rating up to 8000 lbs per square inch (PSI). The flange also has a taper rate that ensures proper seal when tightened with bolts.

Size Range

Weldo flanges are available in a wide variety of sizes, ranging from 1/2″ to 24″, depending on the manufacturer. The size determines the total length and weight of each flange, as well as the number of bolts required to secure it onto the pipe. Most weldo flanges are compatible with common pipe sizes and fit standard ASME B16.5 bolt circles, though they may come in non-standard variations depending on the application.

Pressure Ratings

Weldo flanges come in different pressure ratings, depending on their size and material, ranging from 150# all the way up to 4500# or higher. This denotes how much pressure the flange can withstand before it fails or deforms due to wear or corrosion. You should always match the pressure rating of your weldo flanges with that of your piping system in order to ensure adequate performance and compliance with relevant industry standards.

Bolt Patterns

Weldo flanges conform to either circular or oval shaped bolt patterns, typically denoted by A/N (American National) or D (European) standards respectively. Circular bolt patterns have bolts spaced evenly around its circumference while oval configurations have pairs of bolts located along two parallel sides instead. Depending on your application, you may require a specific type of pattern for proper installation and safety considerations.

Weldo flange materials 

Weldo flange materials include carbon steel, stainless steel, aluminum, brass and bronze for both interior and exterior applications subjecting them to different chemical environments such temperatures related stress cracking or chloride attack resistance requirements needed by certain industries. 

Torque Values 

When bolting weldo flanges to pipes during assembly it is important that correct torque values are specified as part of good maintenance practice so make sure whichever torque value complying document you use has accurate information listed on it according to joint type being considered whether this being plain face joint bolts lined up uniformly across one side then working around in a clockwise direction ending up at where you started from; lap joint bolted from side one repeating this procedure along side two ; etc .
