Inquiry
Hot-pressed (hot-pushed) seamless tees are steel butt-welding seamless pipe fittings. The seamless pipe blank is heated to a high-temperature plastic state, and the branch pipe is extruded and pushed out by means of a mold, achieving integral one-time forming without any assembly welds. This process makes the metal structure dense and uniform, stabilizes wall thickness, and significantly improves pressure resistance and high-temperature performance. The product ends are machined with welding bevels and connected to the pipeline by butt welding. It is suitable for flow distribution and collection in high-pressure process pipelines in petroleum, chemical, electric power, heating, natural gas and other industries. Compared with welded fabricated tees, hot-pressed seamless tees have no hidden risks of weld defects and are a reliable choice for special equipment pressure pipeline projects. We provide three major material series: carbon steel, alloy steel and stainless steel, strictly implement GB/T12459 and ASME B16.9 standards, and can customize non-standard specifications according to project requirements.

Certification/Qualification: Please contact us to confirm
A hot-pressed seamless tee is integrally formed through overall hot-push forming with no weld seams, so there are no hidden risks such as weld seam cracking, pinholes, or leakage, making it suitable for high-pressure special equipment pipelines. In contrast, welded tees carry the risk of weld seam defects and generally cannot be used in high-pressure working conditions.
