Specification

I. Product Overview

TIANYU basket strainers are pipeline filtration devices constructed from stainless steel, carbon steel, etc., achieving solid-liquid separation via a basket-type mesh structure. With bores ranging from DN15 to DN400, they adapt to international flange standards (ANSI, JIS, DIN, etc.), efficiently filtering water, oil, chemical media, etc., under 1.6MPa pressure and 100℃~250℃ temperatures. Their modular design balances versatility with application-specific adaptability for industrial pipeline impurity interception.
