What Is Butt-Welding?
Butt-welding is the process of joining two pieces of material together along a single edge in a single plane. This process can be used on many types of materials, though metal and thermoplastics are the most common. When two sheets of steel are laid side-by-side and joined together along a single joint, this is an example of butt-welding.[……]

In the behavior, we make beveling after shot blasting, bevel ends are fully machined by advanced equipment Double Beveling Machine ensure the height, length, thickness, O.D. and I.D. are all qualified.[……]
Pipe Deterioration
Even when water mains are properly installed, the pipes will deteriorate over time. This deterioration can be slowed by matching the pipe material to the soil or by wrapping the pipe.[……]
What is Galvanized Steel Pipe?
Galvanized steel pipe is a steel pipe that has been coated with zinc. This coating protects the steel from corrosion. It is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing.[……]

What is a Flange gasket？Gaskets for Flange Connections
Flange gaskets are used to create a static seal between two flanges faces, at various operating conditions, with varied pressure and temperature ratings.[……]
Flange Face Surface Finish
The American National Standards Institute (ANSI) code for flanges and flanged fittings (ANSI B16.5) requires that the flange face has a specific roughness to ensure that this surface be compatible with the gasket and provide a high quality seal.[……]
Measure the size of a flange
Place one end of a tape measure on the inside of the flange. The diameter is used to determine what size pipe a flange can be used with, so you must find this information by using the inside of the flange as opposed to the outside.[……]
Applications of flanges
Flanges are integral parts of many engineering and plumbing projects. In many applications, engineers need to find a way to close off a chamber or cylinder in a very secure fashion, usually because the substance inside must differ from the substance outside in composition or pressure. [……]
What is the use of a blind flange?
Blind flange is put at the end of pipe or at the junction that would possibly be a future expansion into that direction. [……]
What is a spectacle blind flange?
A spectacle blind – also known as a figure-8 blind – is generally a piece of metal that is cut to fit between two pipe flanges and usually sandwiched between two gaskets. [……]
