Straight tee, also known as T-type tee, is the most common standard pipe fitting in industrial and civil pipelines, used to achieve 90° vertical branching of pipelines, and to perform functions such as diversion, confluence, bypass, sewage discharge, and sampling. The product structure features a straight main pipe with a vertically branched outlet, smooth transition of the flow channel, low resistance, and low stress concentration, ensuring stable system operation. Guojie straight tees cover two major types: equal-diameter and reducing, manufactured using mature processes such as hot-pressed seamless, hydraulic bulging, integral forging, and plate coil welding, with nominal diameters ranging from DN15 to DN2000, materials including carbon steel, stainless steel, alloy steel, duplex steel, cast iron, etc., adaptable to conditions from atmospheric pressure to ultra-high pressure, and supporting special function upgrades such as wear resistance, thermal insulation, anti-corrosion, and sanitary grade. Products strictly comply with domestic and international standards such as GB/T12459, GB/T13401, ASME B16.9, and are widely used in municipal water supply and drainage, thermal heating, power plants, petrochemical, mining and metallurgy, HVAC and fire protection, clean process piping, and other fields. We provide full-size stock and customization services, welcome to contact us to confirm specific configurations.

A straight tee, also known as a T-type tee, is a standard pipe fitting used for 90° vertical branching in piping systems. The main pipe runs straight through while the branch pipe extends vertically, featuring a simple structure but extremely wide application. It can achieve functions such as flow splitting, flow merging, bypass, drainage, and sampling in pipelines, making it one of the most fundamental connecting components in industrial and civil pipeline networks. Guojie straight tees are manufactured using mature processes such as hot-pressed seamless forming, hydraulic bulging, integral die forging, and plate coil welding, ensuring high product strength, reliable sealing, and smooth flow channels. The product bore range covers DN15-DN2000, with materials including carbon steel, stainless steel, alloy steel, duplex steel, cast iron, etc., meeting different pressure ratings and medium requirements. We strictly implement domestic and international standards such as GB/T12459 and ASME B16.9 to ensure product universality and interchangeability, facilitating engineering installation and maintenance.
Standard and universal: The straight tee is one of the most standard pipe fittings in piping systems, conforming to mainstream standards such as GB/T12459 and ASME B16.9, and can be replaced in place without special modification. Mature processes: According to size and pressure requirements, we offer multiple process options including hot-pressed seamless forming, hydraulic bulging, integral die forging, and plate coil welding, ensuring reliable product performance. Complete material range: Full material coverage including carbon steel, stainless steel, alloy steel, duplex steel, and cast iron, spanning from normal pressure to ultra-high pressure working conditions, meeting different medium and temperature requirements. Wide size range: Bore diameter DN15-DN2000, with regular specifications available in stock, supporting non-standard customization to suit various engineering needs. Upgradable functions: Special functional layers such as wear resistance, thermal insulation, corrosion protection, and hygienic grade can be added according to working conditions, enhancing service life and safety. Flexible procurement: Regular single pieces can be shipped, supporting small-quantity purchases, engineering project support, and complete foreign trade sets, with negotiable delivery times to accommodate different procurement scales.
Straight tees are suitable for all piping systems requiring 90° vertical branching, specifically including: municipal water supply, drainage, and heating pipe networks, used for main pipe branching and household connection; petrochemical plants, used for flow splitting, merging, sampling, and drainage in process pipelines; power plants, used for pipeline branching in cooling water, steam, and oil systems; mining and metallurgy, used for slurry conveying pipelines with high wear resistance and corrosion resistance requirements; HVAC and fire protection, used for branch connections in air conditioning water systems and fire sprinkler systems; clean process piping, used for high-cleanliness pipeline systems in industries such as pharmaceuticals and electronics. Whether for new construction projects or renovation of old pipelines, straight tees are the standard first-choice pipe fitting.

A straight tee refers to a tee where the branch pipe is at a 90° perpendicular angle to the main pipe. It is the most standard T-shaped tee, used for orthogonal branching of pipelines. An ordinary tee may refer to a lateral tee at any angle, but the straight tee is the most commonly used standard component in engineering.
If the diameters of the main pipe and the branch pipe are the same, choose a straight equal tee; if the branch pipe diameter is smaller than the main pipe diameter, choose a straight reducing tee. You can determine this based on the pipeline design drawings.
Common processes include hot-pressed seamless push forming, hydraulic bulging, integral forging, rolled plate welding, and casting. Seamless push forming is suitable for small and medium diameters, forging is suitable for high-pressure conditions, and rolled plate welding is suitable for large diameters. The specific process can be selected according to size and pressure requirements.
