A flange is a component that connects one pipe to another, attached to the pipe ends. There are holes on the flange, and bolts are used to tightly join two flanges. A gasket is used for sealing between flanges. Flanges are divided into threaded (screw) flanges and welded flanges.

A flange is a disc-shaped part, most commonly found in pipeline engineering. Flanges are used in pairs and in conjunction with flanges on valves. In pipeline engineering, flanges are mainly used for connecting pipelines. For pipelines that need to be connected, a flange plate is installed at each connection point.

According to the bending angle, there are certain angles for elbows. The pipe fittings industry has a huge demand for carbon steel elbows. Rough calculations indicate that reaching the peak steel output will require a large amount of carbon steel elbows.

Our factory currently supplies in-stock straight seam elbows, seamless elbows, national standard elbows, secondary standard elbows, and non-standard elbows. Due to the large variety of large-diameter elbows, our selection is complete, prices are reasonable, and we have a comprehensive quality assurance system. This type of elbow generally needs to be manufactured according to specific engineering requirements or drawings. In addition to meeting the pipeline diameter requirements, the specific conditions of the pipeline must also be considered, such as pipeline pressure, fluid viscosity, wear and corrosion, and fluid temperature, among other factors. Because of the presence of welds, non-destructive testing is required.

2. Specific process of production: The raw material for rolled seamless elbows is round pipe billets. The pipe billets are cut into approximately one-meter lengths using a cutting machine and conveyed to the furnace for heating. For welded elbows, corrosion, pitting, rust, or wear may occur in Hebei Mengcun Pipe Fittings Factory products. Gate valves and threaded globe valves have a reverse sealing device; the handwheel is rotated to the topmost position upon user request. The setting of supports depends on pipe diameter, material, wall thickness, load, and other conditions. Once formed, the outer diameter and wall thickness of welded elbows meet the required standards. Green, healthy stainless steel large-diameter elbows are recognized as biocompatible materials, meeting national drinking water hygiene standards and are recyclable.
