Carbon steel tees are used in large quantities and have strong versatility in pipeline mainline branching, medium diversion and merging, and fluid direction switching. We supply according to standards such as ASME B16.9, GB/T12459, SH/T3408, HG/T21634, etc., covering the full range of DN15–DN3000, with wall thicknesses from SCH10 to XXS, and pressure adaptation from PN10–PN100. For small and medium diameters under conventional working conditions, seamless stamping is used, with integral forming and no welds; for small diameter high-pressure working conditions, integral forging is used, with refined grains and no welding weak points; for extra-large diameters above DN600, rolled and welded construction is used, breaking through mold limitations. The surface can be treated with anti-rust oil, sandblasting, galvanizing, anti-corrosion coating, etc., adapting to indoor, outdoor, and buried working conditions. Before purchasing, please provide diameter, wall thickness, material, pressure rating, and quantity, and we will assist in confirming the configuration and providing a quotation.

| Packaging | Carbon steel tees adopt a foreign-trade-grade dedicated packaging system that is moisture-proof, rust-proof, impact-proof, and deformation-proof, adapting to the harsh environments of domestic long-distance transportation and ocean shipping. Small-diameter threaded and socket-welded styles are fitted with plastic thread protectors and port protection sleeves to eliminate thread wear, port deformation, and precision damage. Small and medium-diameter seamless pressed products have their surfaces coated with anti-rust oil, wrapped with waterproof oil paper and pearl cotton, sorted and packed into thickened hard cardboard boxes, with desiccants placed inside to prevent moisture, rust, and oxidation during storage and sea transportation. Medium and large-diameter butt-welded styles have their ports covered with waterproof protective film and their bevels fitted with anti-collision protective rings, strictly preventing collision damage to welding bevels and ensuring on-site alignment precision. Large-diameter rolled products have their outer walls coated with anti-rust primer, externally wrapped with waterproof stretch film and rainproof woven fabric, and solid wood support bases installed at the bottom, |

Carbon steel tees are core pipe fittings used for diversion and convergence in industrial piping systems, mainly installed at branch points of main pipeline lines, medium diversion and convergence points, and fluid direction switching positions. The carbon steel tees we supply comply with standards such as ASME B16.9, GB/T12459, SH/T3408, HG/T21634, covering the full range of DN15–DN3000, with wall thicknesses from SCH10 to XXS, and pressure adaptation from PN10–PN100. According to forming processes, they are divided into three categories: seamless pressing, integral forging, and steel plate rolled welding: for small and medium diameters under conventional working conditions, seamless stamping is used, with integral forming without welds and smooth flow channels; for small diameter high-pressure working conditions, integral forging is used, with refined grains and no welding weak points; for extra-large diameters above DN600, rolled welding is used, breaking through mold specification limitations. Commonly used materials include 20#, Q235B, 16Mn, A234 WPB, A105, suitable for conveying water, steam, oil and gas, air, and other non-strongly corrosive media.
First, complete specification coverage. DN15–DN3000 full-size system, wall thickness SCH10 to XXS, pressure PN10–PN100, specifications required for conventional engineering can be fully equipped in one stop. Second, process matches working conditions. Seamless pressing is used for small and medium diameter medium and low pressure pipe networks, integral forging is used for small diameter high-pressure pipelines, rolled welding is used for extra-large pipe diameters above DN600, and the corresponding process can be selected according to actual working conditions during procurement. Third, flexible material selection. 20# and A234 WPB are general industrial materials, Q235B is suitable for municipal and civil use, 16Mn is suitable for low-temperature heavy loads, and A105 is suitable for high-temperature and high-pressure equipment pipelines. Fourth, customization capability covers non-standard requirements. Non-standard pipe diameters, special wall thicknesses, irregular branch angles, and eccentric diversion structures can be customized according to drawings, samples, or engineering technical agreements. Fifth, surface treatment adapts to multiple environments. Rust preventive oil, sandblasting, galvanizing, epoxy anti-corrosion, asphalt anti-corrosion, and other treatments can be done, suitable for indoor, outdoor, and buried working conditions.
Carbon steel tees are suitable for industrial and civil piping systems without strongly corrosive media. In municipal water conservancy, they are used for main line branching and diversion of urban water supply and drainage, township water supply, farmland water conservancy, and rainwater collection and conveyance pipe networks. In energy and heating, they are used for power plant circulating water, heating steam, waste heat conveyance, and low-pressure gas conveyance pipelines. In petrochemicals, they are used for medium-pressure industrial process supporting of crude oil conveyance, process circulation, product oil pipe networks, and ordinary medium diversion pipelines. In general industry, they are used for plant fluid conveyance, equipment pipeline branching, ventilation and dust removal, auxiliary fire protection pipe networks, and pipeline renovation in industrial parks. Small diameter forged styles are suitable for high-pressure equipment instrument pipelines, large diameter rolled styles are suitable for large-scale infrastructure main pipelines, and conventional pressed styles are suitable for the vast majority of standard industrial pipe networks. Not suitable for strongly acidic and strongly alkaline, high chloride ion extreme corrosion working conditions.
