Where to buy weldolet?

What is a weldolet? Weldolet is the kind of pipe fitting used to make a branch with the littler size of primary pipe. Weldolet normally utilized as a part of piping with high pressure weight and temperature where the connection with the joint type butt weld. Weldolets are principally sorted as butt weld fittings, as these are welded into the branch pipe. The principle favorable position of weldolets is that it limits stress focus as are well-suited for high pressure weight applications.

Black Steel Pipe Vs Galvanized Steel Pipe

What is a black steel pipe? Black steel pipe is non-galvanized steel pipe. Black steel pipe, its name comes from the scaly, dark-colored iron oxide coating on its surface. Black steel pipe is a common iron pipe with no surface treatment. What is a galvanized steel pipe? Galvanized pipe, also known as galvanized steel pipe, is divided into hot-dip galvanizing and electro-galvanizing. The hot-dip galvanizing layer is thick, with uniform plating, strong adhesion and long service life. The cost of electroplating is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipes. After the […]

Seamless Steel Elbow VS Welded Steel Elbow

What is a seamless elbow? The most common raw material for seamless elbow is seamless steel pipe. The tube blank of the elbow is cut by waterjet cutting, hot cutting, etc., and is pushed by the intermediate frequency pushing machine, and then pressed and finished by a hot press, and then subjected to subsequent processing such as groove and non-destructive testing. After leaving the factory, the raw material for rolling seamless elbow is a round tube blank, which is cut by a cutting machine into a billet having a length of about one meter and sent to a furnace for […]
