ANSI / ASME B16.11
Socket Weld Reducing Coupling
A Socket Weld Reducing Coupling is a type of pipe connection where the pipe is inserted into a recessed area of a valve, fitting, or flange. Unlike buttweld fittings, Socket Weld Fittings are mostly used for smaller pipes, typically with a Nominal Diameter of NPS 2 or less.
To connect pipes to valves, fittings, or other pipe sections, fillet-type seal welds are used. Socket Welded Pipe Fittings Joints are a reliable choice when high leakage prevention and strong structural integrity are important factors.
Kaizen Steel Industries has over 10 years of experience in manufacturing forged fittings according to ASME B16.11 and MSS-SP-83 standards. The company is dedicated to providing high-quality products to customers at competitive prices by utilizing innovative production systems and processes.
An ASME B16.11 Coupling is a fitting used to connect two pipes. If the pipes are of different sizes, the 3000 Lb Socket Weld Coupling is called a reducer, reducing coupling, or adapter. There are two types of Socket Weld Couplings in Class 150: regular and slip.
A regular Carbon Steel Socket Weld Pipe Fittings has a small ridge or stop inside. This ridge helps prevent one pipe from being inserted too far, which could cause the other pipe segment to be inserted too little. This ensures a secure connection. On the other hand, a slip Forged Pipe Coupling, sometimes known as a repair coupling, doesn’t have this internal stop. This allows it to be easily slipped into tight spaces.
For example, a slip Socket Weld Coupling Class 3000 can be used to fix a pipe with a small leak caused by corrosion or freezing, or when a pipe has been temporarily cut. Since the stop is missing in this type of coupling, the installer needs to carefully measure and position the slip coupling correctly to ensure it is placed in the right spot.
Socket Weld Coupling Stainless Steel Pipe Fittings are forged products that can be classified by their pressure and temperature ratings. The dimensions of Socket Weld Forged Couplings range from NPS 1/8 inch to 4 inches. We have Socket Weld Half Coupling fittings in stock with three different pressure-temperature ratings.
These 3000 & 6000 class fittings are available in both Threaded and Socket Weld types, including the Socket Weld Coupling.
Kaizen Steel Industries is known as a leading manufacturer, exporter, and supplier of a wide range of Reducing Couplings, including Socket Weld Reducing Couplings.
