On May 6, 2025, we received an inquiry from a French customer. This was the second time the French customer placed an order with us. It was the same product with the same specifications and materials as the last order. This was not just a simple repeat order, but also a great recognition of our product quality and service. We immediately made fine adjustments based on the last quotation and combined with the current market fluctuations, and sent a detailed order confirmation letter to the customer in the shortest time. The customer was very satisfied with our response speed and the accuracy of the quotation.


Shanghai Zhucheng Pipe Fittings Manufacturing Co Ltd.is a company specializing in the production and processing of pipes and fittings. The pipes and pipe fittings we produce are mainly used in the fields of chemical industry, petroleum, natural gas, water conservancy, electric power, marine engineering, etc. The products mainly include seamless pipes, welded pipes, butt weld pipe fittings, high-pressure forged pipe fittings and flanges of various sizes. The materials include carbon steel, stainless steel, alloy steel, low-temperature steel, duplex steel, base alloy, etc.


We are fully capable of customizing and producing this type of combined pipe clamp with one end socket and one end thread according to your specific needs. This will undoubtedly provide you with more diversified solutions in engineering design and construction.

Dimensional Inspection of Forged Coupling


1. Socket Bore Diameter:

This is the diameter of the inner hole where the pipe is inserted into the socket. It must be measured accurately to ensure that the pipe can be inserted smoothly and leave the necessary expansion gap. ASME B16.11 has strict regulations on the inner diameter of the socket for different pipe diameters and pressure levels.


2. Socket Depth:

Measure the depth of the pipe inserted into the socket. This depth determines the length of the weld and the stability of the connection.


3. Overall Length of the Coupling:

Measure the overall length of the pipe coupling to ensure that it meets standard or custom requirements.


4. Wall Thickness:

Measure the wall thickness of each part of the pipe coupling, especially the wall thickness of the socket, to ensure that it meets the minimum wall thickness requirements for the design pressure level.


5. Thread Profile and Pitch:

Ensure that it meets the standard (such as ASME B1.20.1 NPT tapered pipe threads).


6. Effective Thread Length:

Measure the effective length of the thread to ensure sufficient engagement depth for sealing and connection strength.
