Engineered for Durability and Strength

WPHY 52 Carbon Steel Stub Ends are forged and heat-treated for structural integrity, ensuring long-term reliability in high-pressure and fluctuating temperature conditions. Their tensile strength of at least 520 MPa and maximum hardness of 20 HRC contribute to stability even in challenging environments. The seamless or welded production technique further elevates their strength, providing leak-proof and efficient connections for critical pipeline applications.

Adaptable Design and Customization

These stub ends are available in short and long lengths, with thicknesses such as Sch40, Sch80, Sch160, or custom dimensions to match specific project requirements. The outer diameter can range from 1/2 inch to 24 inch, while length customization enables precise fitment in any pipeline system. Surface options like black paint and anti-rust oil coatings help resist corrosion and extend service life.

Certified Quality Assurance

Every stub end meets ASTM A860 MSS SP75 quality standards and undergoes hydrostatic, ultrasonic, and dimensional inspections. Each piece is stamped with clear size, grade, and heat number markings for traceability. The 0.5 mm tolerance and meticulous quality checks assure precise alignment and seamless integration in pipe fitting and flange connections.
