Profile: Shanxi Enrey Forging Co., Ltd. is a manufacturer of Flanges and Forgings. We are an ISO 9001:2000 certified company. Our product line includes Welding Neck, Blind, Slip-On, Threaded, Socket Welding, Lap Joint, Orifice, Figure-8 Blanks, and Welding End Flanges.
We can supply main material of pipe flanges include carbon steel flanges, stainless steel flanges, and alloy steel flanges. We also can produce the DIN flange, and the forgings according to the customers drawings, for example, rings and shafts.
Welding Neck Flanges
The Welding neck flange is normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange.
The blind flange is a flange without a bore. It is used to close off the ends of a piping system and/or a pressure vessel opening. It also permits easy access to the interior of a line or vessel once it has been sealed.
The Slip-on flange has a low hub because the pipe slips into the flange prior to welding. It is welded both inside and out to provide suffcient strength and prevent leakage.Slip-on flanges are all bored slightly larger than the O.D. of the pipe. They are preferred over welding neck flanges.
Threaded (Screwed) flange is similar to the Slip-On flange, but the bore is threaded. Its chief merit is that it can be assembled with our welding, explaining its use in low pressure services at ordinary atmospheric temperatures, and in highly explosive areas where welding create a hazard.
Socket Welding Flanges
The socket welding flange is similar to a slip-on flange except it has a bore and a counterbore dimension. The counterbore is slightly larger than the O.D. of the matching pipe, allowing the pipe to be inserted into the flange similar to a slip-on flange. The diameter of the smaller bore is the same as the I.D. of the machine pipe. A restriction is built into the bottom of the bore which sets as a shoulder for the pipe to rest on. This is eliminates any restriction in flow when using a socket welding flange.
Lap Joint Flanges
The lap joint flange is practically identical to a slip-on flange except it has a radius at the intersection of the bore and flange face. This radius is necessary to have the flange accommodate a lap joint stub end. Normally, a lap joint flange and a lap joint stub end are mated together is an assembly system.
Orifice flanges are widely used in conjunction with orifice meters for measuring the rate of flow of liquids and gases. They are basically the same as standard welding neck and slip-on flanges except for the provision of radial, tapped holes in the flange ring for meter connections and additional bolts to act as jack screws to facilitate separating the flanges for inspection or replacement of the orifice plate. In choosing the type of orifice flange, the considerations affecting the choice of welding neck and slip-on standard flanges apply with equal force.
Spectacle Blind Flange
Our Spectacle Blind Flange is a pressure-retaining plate with one solid end and one open end connected with a web or tie bar.
Our Reducing Flanges are designed for use in changing diameters in a piping system. A reducing flange consists of a flange with one specified diameter having a bore of a different and smaller, diameter. Except for the bore and hub dimensions, the flange will have dimensions of the larger pipe size. We provide three types of Reducing Flanges such as Welding Neck, Slip-On and Threaded.
