BSP DN25 ASTM A182 Stainless Steel Forged Fitting F347 Cap Threaded

Forged pipe fittings are high-strength components used to connect, branch, or seal pipelines in harsh industrial environments such as high temperature and high pressure. Through forging process (i.e. applying pressure to the heated metal billet to shape it), the pipe can obtain a dense and uniform internal metallographic structure and superior mechanical strength.

Compared to cast or bar directly machined pipe fittings, forged pipe fittings have superior pressure bearing capacity, fatigue resistance, and impact resistance, making them a reliable choice for ensuring the long-term and safe operation of critical pipeline systems.

F347 is a niobium (Nb) stabilized austenitic stainless steel designed specifically for high-temperature applications. Similar to F321, the stabilizing element "niobium" added to it can preferentially bind with carbon when the material undergoes high temperatures (425-850 °C) or welding, thereby inhibiting the precipitation of chromium carbide and effectively preventing intergranular corrosion.

This allows F347 to maintain excellent corrosion resistance without annealing treatment after welding, making it very suitable for welding structural components that require long-term service in high-temperature environments.

The F347 forged pipe cap provides a reliable and detachable sealing solution for the end of high-temperature and high-pressure pipelines. They are widely used in:

• Petroleum refining equipment
• Chemical reactor nozzles
• High-temperature steam pipelines
• Boiler equipment

Under these conditions of continuous high temperature and thermal cycling, F347 material can ensure the structural integrity of the cap body and threaded connections, avoid the risk of strength reduction or leakage caused by high temperature corrosion, and ensure equipment safety.

SMLSCO supply strategy for forged pipe fittings is consistent with our flange business, with a core focus on "driving rapid manufacturing with semi-finished inventory". We strategically maintain a large number of certified stainless steel round bar raw materials and forging blanks of various grades, rather than a massive amount of finished products.

This model gives us great production flexibility, allowing us to quickly schedule production based on customer demand for special materials or specific specifications such as F347, thereby providing delivery speeds far faster than the market.

SMLSCO's forged pipe fittings are all produced at our exclusive manufacturing base - Wenzhou Yongheng Steel Industry. The factory has not only passed ISO and PED certifications, but its quality system has also obtained the rigorous NORSOK M650 certification for the Norwegian petroleum industry.

We have dozens of precision CNC machine tools to ensure that the threads, sockets, and dimensions of every pipe fitting achieve extremely high precision. This strong internal manufacturing capability is our confidence guarantee in continuously providing high-quality special pipe fittings for the high-end industrial sector.
