In September, the order from the UAE customer was successfully completed. The product of this order is quite special, as it is a relatively unique type of flange product: long neck welding flange.

The long neck welding flange is a self-reinforced flange with a single piece design, which plays an important role in various applications as an efficient and reliable connection method.The long neck welding flange purchased by the UAE customer in this order has a size of 4inch, pressure CLASS150, neck length of 228.6mm, wall thickness of 9.52mm, sealing surface form of RTJ, and material is ASTM A105,product standard is ASME B16.5.

The long neck welding flange (LWN) is designed to replace the welded neck flange and pipe fitting. This design reduces the stress on the neck and transfers it to the bottom connected to the vessel.The design of the long welding neck provides a thicker neck for high-pressure and high-temperature applications.

The flange end and sealing surface are produced according to the ASME B16.5 production standard, which is suitable for pipeline sizes ranging from 1/2 inch to 24 inch. The ASME B16.47 production standard is suitable for pipeline sizes ranging from 26 inch to 60 inch.Generally, the larger the nominal size and pressure, the longer the neck length.

The neck diameter of the long neck welding flange is the same as the pipe size, and the neck length is generally 9 inch (228.6mm), 12 inche (304.8mm), and 16 inche (406.4mm). It can also be customized according to the actual needs of the customer based on the design drawing.
