Manufacturers of MSS SP-97 Branch Outlet Fittings, Weldolet Fittings, Nipolet Pipe Fitting, Sockolet Fitting, Threadolet Fittings, Elbolet Fitting in India.
Branch Connection Fittings:
Branch Connection Fitting is also named as Outlet fittings. Olets are a family of forged products used to make 90 degree or 45 degrees integrally reinforced branch connections from a header pipe or run pipe to an outlet pipe or branch pipe. Olet fittings have some outstanding advantages such as low cost, reliability and safety, standardization, simple construction, convenient design selection, and improved media flow channels. Outlets come with threaded, socket-weld, and butt-weld end connections. Branch fittings are available in all dimensions, bores, types (i.e. Weldolet, Nipolet, Sockolet, Threadolet, Elbolet), sizes, and classes, in a wide range of stainless steel, chrome-moly, and other alloys.
To place an outlet instead of the tee, A hole is cut in the side of the pipe, the O’lets are welded in place over the hole and then the additional length of pipe is attached to the outlet. Sometimes the run size is given as a possible range or consolidation. this means the outlet can be used on several different pipe sizes. for example, a 36-3 x 1 outlet could be used to branch 1″. pipe off of any run pipe from 3″ up through 36″.

Branch Fittings Types:
Weldolet® is a registered name. Another often used name is Welding Outlet. Creative Piping Solutions designed and manufacture Weldolet Fittings to minimize stress concentrations and provide integral reinforcement. MSS-SP 97 welding outlet is the most popularly used branch connection fitting falling under the buttweld fittings family. Buttweld Outlets are available in a wide range of dimensions. It is well-suited for high-pressure weight applications. There are three pressure grade STD, XS, and Sch160 for the weldolet.
Buttweld Branch Outlet is contoured to match the curve on the headed pipe and beveled on the branch side to mate up with a beveled piece of the branch pipe. We are leading producers of Weldolet using ASME B16.11, B16.9, ASME B16.25, and EN Standards. The most popular purchase materials of Welding Outlets are A105 and A234. We are the topmost exporters of Class 3000 Long Weldolet in the UK and UAE.
Nipolet Pipe Fitting:
Nipolet is also known as nipple outlet. It is mostly used for valve installation and exhaust. ASME B16.11 Nipolets are manufactured in lengths ranging from 3.1/2 inches to 6.1/2 inches and for Sch 160, XS, and XXS schedules. ASTM A105 Nipolet Manufactured for Extra Strong and Double Extra Strong applications in Class 6000, Clase 3000. Available with male-socket weld or male threaded outlets.
A MSS SP-97 sockolet has the same basic design as a Weldolet and threadolet where the major difference is that the branch pipe is connected to the run pipe, via the fitting, with a socket weld connection as per ASME B16.11. Sockolets belong to the “socket fittings” family and are also popularly known as socket weld outlets and are available in Class 3000, Class 6000, and Class 9000. ASTM A182 and A105 Sockolet are used for lower pressure applications, and smaller pipe diameters (as compared to Weldolets).
MSS SP 97 Threadolet is also known as threaded outlet. ASME B16.11 Threadolet is a type of branch connection and it is threaded without welding. Thredolets are used for low-pressure 90-degree pipe branches. The threading is generally of the NPT type and conforms to the ASME B1.20.1 specification. A105 Threadolet is available in the size range of 1/2″ to 2″ and is welded over a hole either drilled or burned in the pipe. The pressure s usually Class 3000 and Class 6000.
Threaded Branch Outlet is contoured to match the curve of the header pipe and the branch side of the fitting has an NPS thread according to ASME B1.20.1. Normally, Thread Branch Outlet Fittings are used for NPS under 2″. Creative Piping Solutions is ISO certified supplier and exporter of Threadolet Fittings in the UK, UAE, and Australia.
We are manufacturers of Elbolet Branch Fittings using ASME B16.9 and MSS SP-97 Standards. Elbolet (also known as elbow outlet) is used to provide branch connections on 90 or 180 degrees short radius elbows(seldom used) or long radius elbows(most common). Elbolets are available with socket weld/threaded connections or with butt weld connections in class 3000 or class 6000.
