Steel Welding Neck Flange

High quality Steel Welding Neck Flange is the most popular product in our company.We are one of the leading manufacture&supplier of steel welding neck flange, selecting the high quality raw material form large steel plant,guaranteed by various certificates.

Steel Welding Neck Flange is distinguished from other types of flanges by its long tapered hub and the smooth transition of the thickness of the butt weld area connected to the pipe. The Long cone Hub provides flanges with appropriate reinforcement strength and resistance to the angle of the offering. The smooth transition of the thickness of the flange under the condition of repeated bending is very beneficial to the influence of the taper of the thickness of the tube wall, and the endurance strength of the welding neck flange component is equivalent to a pipe between the butt welding joint and the welding pipe in practice. Thus, this type of flange is preferred for each serious service condition, whether it is due to high pressure or from zero or elevated temperatures, and whether the loading conditions are basically constant or fluctuating between the broad limits.
