Detailed Introduction

The British standard tee is used for the diversion, confluence, and branch connection of media in British pipeline systems, and is compatible with the traditional British imperial inch size system and the BSP British pipe thread system. Products are divided into two official grades: Type A pressure-reducing type and Type B full-pressure type, corresponding respectively to low-pressure civil working conditions and high-pressure industrial working conditions. Specifications range from DN15 to DN1200 (1/2 inch to 48 inch), wall thickness covers BS SCH standard wall thickness, STD, XS, and XXS thickened high-pressure specifications, and pressure ratings cover PN10 to PN160. Commonly used materials include Q235B, S275JR, S355JR carbon steel, 304, 316L stainless steel, and low-temperature alloy steel. The production process adopts seamless hot-pressed integrated forming and large-diameter rolled and welded processes, dimensions follow the imperial tolerance system, and it is suitable for butt welding with British seamless steel pipes and galvanized steel pipes. Before leaving the factory, it undergoes hydrostatic testing, non-destructive testing, and spectral testing, and a full set of English qualification documents can be issued, for engineering acceptance, customs clearance, and foreign trade bidding in Commonwealth countries.

At the same time, it implements the BS EN 10253-2/4 butt-welding pipe fitting standard and the BS 1965 high-pressure pipe fitting standard, with Type A/B grades clearly distinguished, matching the engineering acceptance requirements of the United Kingdom and Commonwealth countries
Specifications cover DN15-DN1200 (1/2 inch-48 inch), pressure ratings PN10-PN160, wall thickness covers the full series of STD, XS, XXS, and SCH10-SCH160, and supports non-standard thickened customization
Materials cover Q235B, S275JR, S355JR carbon steel, 304, 316L stainless steel, and low-temperature alloy steel; carbon steel is suitable for -20℃ to 450℃, and stainless steel is suitable for -60℃ to 600℃
The seamless hot-pressed integrated forming process is used for small and medium diameters, while large diameters adopt a rolled and welded process with 100% non-destructive testing, and before leaving the factory they undergo hydrostatic testing and spectral testing
Compatible with the British imperial inch size system and BSPP/BSPT British pipe threads, suitable for butt welding with British seamless steel pipes and galvanized steel pipes
A full set of English qualification documents can be issued, suitable for engineering acceptance, customs clearance, and foreign trade bidding in Commonwealth countries
The minimum order quantity for conventional in-stock standard specifications starts at 10 pieces, supporting small in-stock trial orders and mixed batches of the full product range
