What types of pipes use necked slip-on flanges, and what types of pipes use necked butt-welding flanges?

Introduction to Alloy Steel SO Neck Slip-on Flange: As the name suggests, the Alloy Steel SO Neck Slip-on Flange is a slip-on flange or flange plate made of alloy steel. It belongs to the category of neck slip-on flanges. Alloy Steel SO Neck Slip-on Flanges are aesthetically pleasing, have a smooth and flat surface, are resistant to acids and alkalis, corrosion-resistant, and have strong performance characteristics. The English designation for neck slip-on flanges is SO.

Carbon steel elbow fabrication

Cangzhou Aosendike Pipe Fittings Manufacturing Co., Ltd. will guide you through information on carbon steel elbow manufacturing. Elbows are a common pipe fitting in piping systems, and a large number of fittings are used at bends. The main function of elbows is to control and maintain pipelines. Control of components such as steering wheels, engines, and gearboxes is primarily achieved through the steering wheel. Because elbows are mostly made of steel, their surfaces are smooth and bright, giving them good wear resistance. Elbows used in piping systems are for turning and are irreversible fittings. They constitute a large proportion of piping systems. Elbow

Why do different projects have different requirements for elbow wall thickness?

In industrial piping systems, elbows are crucial fittings for fluid diversion. Many buyers frequently encounter varying wall thickness requirements when requesting quotes, such as SCH20, SCH40, SCH80, and even SCH160. Many ask: why do different projects have such different wall thickness requirements for carbon steel elbows?

Basic technology of carbon steel pipe elbows

The basic manufacturing process for carbon steel pipe elbows is as follows: First, polygonal annular shells or polygonal sector shells sealed at both ends are welded together. After filling the interior with a pressure medium, internal pressure is applied. Under the action of internal pressure, the cross-section gradually changes from polygonal to circular, eventually forming a circular annular shell. As needed, the circular annular shell can be cut into four 90-degree elbows, six 60-degree elbows, or other specifications of elbows. This process is suitable for manufacturing large elbows of various specifications with a pitch circle diameter to inner diamete
