SMLSCO Forged Fitting Manufacturing Process
The excellent strength of SMLSCO pipe fittings comes from rigorous
forging processes. We use standard round bars as raw materials,
which are cut, heated, and then forged as a whole on a forging
press. This process greatly refines the internal grain structure of
the metal and eliminates potential metallurgical defects.
Subsequently, the forged blank undergoes heat treatment and
precision CNC machining to form precise socket dimensions and
groove angles, ensuring full compliance with the dimensional
tolerance requirements of ASME B16.11.
Why Choose SMLSCO?
SMLSCO's forged pipe fittings and flanges are produced at our
exclusive manufacturing base - Wenzhou Yongheng Steel Industry. The
factory has a monthly production capacity of 350 tons, equipped
with 38 CNC lathes and 8 CNC drilling machines, ensuring the
accuracy and efficiency of large-scale production. Of particular
importance is that our factory quality system has passed ISO, PED,
and the rigorous NORSOK M650 certification for the Norwegian
petroleum industry. This indicates that we have the ability to
continuously and stably provide forged pipe fittings that meet the
highest quality standards for high-end industries such as chemical
and offshore oil.
What is Forged Coupling?
Forged coupling is a high-strength pipe fitting used to connect two
sections of pipes in a straight line. It is mainly divided into two
forms: Full Coupling, with both ends having sockets or threads,
used to connect two pipes; And half coupling, with one end as a
socket or thread and the other end as a flat butt welding end, is
commonly used for direct welding on container walls or large
diameter pipelines as a branch connection port for small diameters.
What is Socket Weld Connection?
Socket welding is a reliable connection method designed
specifically for high-pressure, small-diameter pipelines. During
construction, insert the end of the pipeline into the socket of the
pipe fitting, and reserve an expansion gap of about 1.5mm between
the pipe end and the bottom of the socket. Then, perform corner
welding on the outside of the pipe fitting. This connection method
has high strength, good airtightness, and can ensure the relative
smoothness of the internal flow channel of the pipeline. It is
widely used in industrial fields that have strict requirements for
sealing and pressure bearing capacity.
