T/CGMA 0409-2023 Polycrystalline silicon equipment wear-resistant ball valve
Basic Information
Scope
Scope: This document defines the terms and definitions of wear-resistant ball valves for multi-product silicon devices, and specifies their structural forms, technical requirements, materials, test methods, inspection rules, marking, protection, packaging, and storage and transportation. This document applies to wear-resistant ball valves for multi-product silicon devices with nominal pressures of PN10~PN160 or Class150~Class900, nominal sizes of DN15~DN800 or NPS1/2~NPS32, and operating temperatures of -29°C~600°C, featuring flange-type end connections.
