Have you ever seen a Socket Weld contraction ring ?. It is a split ring that is engineered and designed to give a pre-measured 1/16" minimum gap for socket welds. Made from a certified stainless steel, and resists corrosion from chemicals, radioactive materials and water. Once inserted into the fitting the ring becomes a permanent part of the joint.
(2) Class 150 flanges except Lap Joint will be furnished with 0.06″(1.6mm)raised face, which is included in 'Thickness'(t) and 'Length through Hub'(T1),(T2). (3)For Slip-on, Threaded, Socket Welding and Lap Joint Flanges, the hubs can be shaped either vertical from base to top or tapered within the limits of 7 degrees. Nominal Pipe Size

The codes applicable to the welding of socket weld fittings require that the tube be inserted into the socket until bottomed against the stop. The tube is then to be backed out approximately 1/16 of an inch and then welded. If the tube is not backed out, but welded when against a flat bottom stop, the contraction of the weld fillet and
9. GLAND AND FLANGE. The gland, gland flange assembly utilizes a separate, two piece design. This self aligning design allows the flange to be unevenly tightened while the gland maintains it's parallel alignment with the stem and stuffing box. 10. GLAND BOLTS AND NUTS. The steel/stainless steel gland bolt and nut assembly is a stud, double nut arrangement.
Carbon steel is a steel with carbon content up to 2.1% by weight. Where in AISI defines: No alloy element (minimum content) required, as of Cr, Mo, Ni, Ti, Va and etc. Specified minimum of Cu shall …
Slip-on Flanges. Slip-on flanges are very common and are available in a large range of sizes to accommodate systems with higher flow rates and throughput. Simply match the flange to the outer diameter of the pipe you intend to connect. Installation is slightly more technical as you'll need fillet weld both sides to secure the flange to the pipe.

ASME Standard B16.11 provides dimensions and requirements for Socket weld Fittings of sizes 1/8″ and upto 4″. But in most piping material specifications for process plants, only 1/2″ to 11/2″ size socket weld fittings are used. These fittings are made with forging process. Socket weld fittings are available in ratings 300#, 600# and 900#. Reducing […]
17-05-2020· Socket weld fittings are very reliable but are time-consuming to install in a piping system (due to the heavy workload caused by welding operations on small parts). Socket weld fittings are available in sizes from 1/8 to 4 inches and in classes between 2000# and 9000#. The typical applications for socket weld fittings are: Steam
04-11-2009· 2007 31.1 " 127.4.4 Fillet Welds. In making fillet welds, the weld metal shall be deposited in such a way as to secure adequate penetration into the base metal at the root of the weld. Filletwelds may vary from convex to concave. The size of a fillet weld is determined as shown in Fig. 127.4.4(A). Typical minimum fillet weld details for slip-on flanges and socket-welding components are shown ...
20-09-2017· The key types of flanges are the welding neck, long welding neck, slip-on, socket weld, lap joint, threaded and blind flanges. In addition to these standard flanges, some special ones exist, called Weldoflange/Nipoflange and Elboflange, swivel flange, expander/reducer flange, and orifice flanges. YouTube.
