Sanghvi Internationalis acknowledged as a manufacturer, exporter & suppliers of Weld Neck Flange & Stainless steel Flanges (Gr. 304, 304L, 316, 316L) available in a variety or grades, materials, and finishes, in metric and inch sizes. These Weld Neck Flange are manufacture in different Material of Flanges like SORF Flanges, Carbon Steel Weld Neck Flanges, Stainless Steel Weld Neck Flanges, Alloy Steel Weld Neck Flanges, Duplex Steel Weld Neck Flanges, Inconel Weld Neck Flanges, Monel Weld Neck Flanges, Hastelloy Weld Neck Flanges, Copper Nickel Weld Neck Flangesin India & Asia, conform to Slip On specifications. Weld neck pipe flanges are connected to the pipe by welding the pipe to the neck of the pipe flange, which helps to pass on the stress from the weld neck to the pipe itself. This also reduces high stress concentration at the base of the hub of the weld neck pipe flanges. Weld neck pipe flanges are generally used in high pressure applications, where hot or cold temperatures exist. The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe

Sanghvi International is acknowledged as a manufacturer, exporter & suppliers of Threaded Flange & Stainless steel Flanges (Gr. 304, 304L, 316, 316L) available in a variety or grades, materials, and finishes, in metric and inch sizes.

Threaded flanges are widely used in low pressure piping systems, as no welding is involved while connecting the flanges to pipes or other equipment. However, the flange may be welded around the joint after assembly, but it is not considered a satisfactory method of increasing its applications. Threaded flanges are also known as screwed flanges and are similar to slip-on flanges, but the bore is threaded to enable assembling without welding. Threaded pipe flanges are usually used with pipes that have external threads.

A spectacle blind is a safety device used to isolate a section of line or piece of equipment when the line or equipment needs to be inspected or removed from service. It is different than a valve in that the blind is a permanent or long term isolation device. A spectacle blind is machined from a single piece of metal that is cut to match the pipe size, fit between two pipe flanges and requires an additional gasket when it is installed. Also, the bolts will need to be lengthened depending on what piping class and size blind is used. The thickness of the spectacle blind is specified based on the line pressure and pipe size. pectacle Flanges, Spectacle Blind Flange Production Range Spectacle Flanges Range ½” (15 NB) to 48″ (1200NB) in 150 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, 2500 LBS ASA 150, ASA 300, PN 6,10,16,25, 40,64,100,160 ETC.

Sanghvi International is acknowledged as a manufacturer, exporter & suppliers of Socket Weld Flange & Stainless steel Flanges (Gr. 304, 304L, 316, 316L) available in a variety or grades, materials, and finishes, in metric and inch sizes.

Socket weld flange is similar to the slip-on flange in outline, but the bore is counter-bored to accept pipe. Socket welding pipe flanges are typically used on smaller sizes of high pressure pipes. Socket weld flanges are widely used in high pressure systems such as hydraulic equipment and steam lines. Socket weld pipe flanges are attached by inserting the pipe into the socket end and then applying fillet weld around the hub of the flange. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. An optional internal weld may be applied in high stress applications

Sanghvi International is acknowledged as a manufacturer, exporter & suppliers of Slip On Flange & Stainless steel Flanges (Gr. 304, 304L, 316, 316L) available in a variety or grades, materials, and finishes, in metric and inch sizes.

The flange is slipped over the pipe and then welded both inside and outside to provide sufficient Strength and prevent leakage. This flange is used in preference to weld necks by many users because of its lower cost and the fact that less accuracy is required when cutting pipe to length.

Our forged flanges cover the range of Plate/Plain Welding Flanges (PL flange), Slip-on Flanges (SO flange), Welded Neck Flanges (WN flange), Blind Flanges (BL flange), both RF(Raised Face) and FF(Flat Face), also Threaded/screwed Flanges (TH flange), Socket Welding Flanges (SW flange), Ring Type Joint Flanges (RTJ flange), Lap Joint Flanges (LJ flange), etc.

Orifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. Pairs of pressure "Tappings", mostly on 2 sides, directly opposite each other, are machined into the orifice flange. This makes separate orifice carriers or tappings in the pipe wall unnecessary. Orifice Flanges generally come with either Raised Faces or RTJ (Ring Type Joint) facings. They are, for all intensive purposes, the same as weld neck and slip on flanges with extra machining. The image on the right shows a set Orifice Flanges, where a Orifice Plate is mounted and a jack screw is machined. This jack screw is used to facilitate separating the flanges for inspection or replacement of the Orifice Plate and gaskets. The range of orifice flanges covers all standard sizes and ranges, and all common flange materials. Flanges are available in Welding Neck, Slip On, and Threaded form, and are typically supplied with two 1/2" NPT tappings in each flange. ASME B16.36 covers Dimensions and dimensional tolerances from orifice flanges (similar to those covered in ASME B16.5) that have orifice pressure differential connections. Coverage is limited to the following flanges: Welding Neck Classes 300, 400, 600, 900, 1500, 2500 Slip On Class 300 Threaded Class 300

Sanghvi International is acknowledged as a manufacturer, exporter & suppliers of Lapped Joint Flange & Stainless steel Flanges (Gr. 304, 304L, 316, 316L) available in a variety or grades, materials, and finishes, in metric and inch sizes.

Lap Joint Flanges are similar to other types of industrial flanges, but it does not have a raised face. Lap joint flanges are used in conjunction with a “Lap Joint Stub End”. The total initial cost of a lap joint flange along with a stub end is around one-third higher than that of comparable welding neck flanges. The pressure holding capacity of lap joint flanges is comparatively lower, and the fatigue life for the assembly is only one tenth that of welding neck flanges.The lap joint flange with the stub end assembly is normally used in piping systems which require regular dismantling for inspection and cleaning. These flanges slip over the pipe, and are not welded or otherwise fastened to it. Bolting pressure is transmitted to the gasket by the pressure of the flange against the back of the pipe lap (Stub End).
