A182 F55 / S32760 Weldolet Super Duplex Forged Fitting, MSS SP-97 Branch Connection For Desalination Plants
What is a A182 F55 weldolet?
A weldolet is a forged, butt‑weld branch connection fitting designed to create a reinforced outlet from a main pipeline, complying with MSS SP‑97. It features a contoured body that matches the curvature of the run pipe, distributing stress evenly and enhancing structural integrity.
Made from A182 F55 (UNS S32760) super duplex stainless steel, it offers exceptional strength, high resistance to chloride pitting, crevice corrosion, and stress corrosion cracking (SCC), making it ideal for harsh environments like offshore oil and gas, seawater systems, sour service, and chemical processing.
Weldolets are welded directly to both the main pipe and branch pipe via beveled ends, providing a smooth, leak‑proof connection. They replace traditional tees and unreinforced saddles, offering better pressure rating and durability. Common sizes range from 1/2" to 36" for main pipes and 1/8" to 24" for branches.
Advantages of A182 F55 / UNS S32760 Weldolet
A182 F55 (S32760) is a super duplex stainless steel that delivers exceptional performance for weldolets, especially in harsh environments.
Extreme corrosion resistance
Outstanding resistance to chloride pitting, crevice corrosion, and stress corrosion cracking (SCC) – far better than 316L and standard duplex
High strength & pressure capacity
Higher tensile and yield strength than austenitic grades, allowing reliable use in high-pressure pipelines.
Excellent seawater resistance
Ideal for offshore, marine, desalination, and brackish water systems.
Sour service compatible
Performs well in H₂S-containing oil/gas applications.
Long service life & low maintenance
Reduces replacement, leakage risk, and lifecycle cost.
Perfect for weldolet design
Forged contour provides a strong, leak‑proof branch connection with superior structural integrity.
