Тредолет / ASME B.31
TECHNICAL DESCRIPTION
Tees are welded-threaded joints that are used as branch pipes in pipelines, providing a removable branch from the main pipeline.
Dimensions:1/2″ – 1
Threadolet fittings manufactured in compliance with ASME B31 standards are engineered for high-performance industrial piping systems. These forged branch connections provide a robust, leak-proof solution for creating threaded outlets on pipes, vessels, and headers. Designed to meet rigorous pressure and temperature requirements, Threadolets ensure structural integrity and operational safety in demanding environments such as oil and gas, chemical processing, and power generation facilities.Key features of our ASME B31-compliant Threadolets include:Precision machining for perfect thread engagement and seal integrityFull penetration weld design for superior strength and fatigue resistanceMaterial certifications traceable to ASTM/ASME specificationsAvailable in various sizes and pressure classes to match system requirements100% non-destructive testing and quality assurance documentationThese fittings are ideal for maintenance, repair, and operations (MRO) applications where reliable branch connections are critical. The threaded design allows for easy installation of instruments, drains, vents, and auxiliary connections without complex welding procedures. Each Threadolet undergoes strict quality control to guarantee dimensional accuracy and performance consistency.Our Threadolet products support efficient system modifications and upgrades while maintaining compliance with international pressure piping codes. Engineered for longevity and reliability, they represent the industry standard for safe and efficient piping network modifications.
