| Distance from the center to the end face | DN20 iso tee is 29mm; DN25 iso tee is 38mm; DN32 iso tee is 48mm and so on. | ||
| Total length | usually the total length of iso tee is about 2 times of the distance from the center to the end face plus the length of the branch pipe, the reducer tee needs to be calculated according to the specific specifications, such as DN20×15 reducer tee the distance from the center to the end face is 29mm, if the length of the branch pipe is 30mm, the total length is about 88mm. | ||
| Branch length | generally between 30mm-150mm, such as DN50 Tee branch length may be 50mm, DN100 Tee branch length may be 80mm. - Interface center distance: equal diameter tee interface center |
||
| Interface center distance | equal diameter tee interface center distance according to the nominal diameter has a fixed proportional relationship, such as DN20 equal diameter tee interface center distance of 29mm; reducer tee needs to be determined according to the specific size, such as DN40 × 25 reducer tee, the main DN40 center distance from the end face distance of 57mm, the center distance from the end face of the branch DN25 distance is also 57mm. | ||
| Pressure Parameter | Nominal pressure | PN0.25MPa, PN0.6MPa, PN1.0MPa, PN1.6MPa, PN2.5MPa, PN4.0MPa, PN6.3MPa, PN10.0MPa, PN16.0MPa, PN25.0MPa, PN42.0MPa and so on. | |
| Shell test pressure | 0.375MPa at nominal pressure PN0.25MPa; 0.9MPa at PN0.6MPa; 1.5MPa at PN1.0MPa, etc. | ||
| Seal test pressure | 0.275MPa for nominal pressure PN0.25MPa; 0.66MPa for PN0.6MPa; 1.1MPa for PN1.0MPa, etc. | ||
| Working pressure | at different temperatures, the working pressure will change. Such as 304 material stainless steel tee, in 20 ºC, PN1.6MPa working pressure of 1.6MPa; in 100 ºC, the working pressure may drop to 1.4MPa or so, according to the material and medium characteristics to determine | ||
| Material Parameters | Common materials | 304 (06Cr19Ni10), 304L (022Cr19Ni10), 316 (06Cr17Ni12Mo2), 316L (022Cr17Ni12Mo2), 321 (06Cr18Ni11Ti), 310S (06Cr25Ni20), duplex steel 2205, 2507, etc. | |
| Main alloying elements | - 304: Cr content 18%-20%, Ni content 8%-10.5%. - 304L: Cr content 18%-20%, Ni content 8%-12%, C content ≤ 0.03%. - 316: Cr content 16%-18.5%, Ni content 10%-14%, Mo content 2%-3 - 316L: Cr content 16%-18.5%, Ni content 12%-15%, Mo content 2%-3%, C content ≤0.03%. - 321: Cr content 17%-19%, Ni content 9%-12%, Ti content ≥ 5 × C%. - 310S: Cr content of 24%-26%, Ni content of 19%-22% |

| Manufacturing Parameters | Manufacturing process | Hydraulic expansion | suitable for less than DN400 standard wall thickness stainless steel tee, equipment tonnage, a high forming efficiency, can make the main pipe and shoulder wall thickness increase |
| Hot pressing | suitable for DN400 and above or special wall thickness requirements of the tee, need to heat the billet to a certain temperature and then pressed in the mold mold forming | ||
| Casting | Complex shaped tees can be manufactured, suitable for small batch, large size or complex structural requirements, relatively low cost, but the quality and performance is slightly inferior to forging and expansion tees. | ||
| Forging | by applying pressure to the billet to make it shape, can improve the metal organization and performance, commonly used in high-pressure, high-temperature and other demanding working conditions of the tee manufacturing, good quality but high cost. | ||
| Execution standards | GB/T 12459, GB/T 13401; American Standard ASME B16.9, MSS SP-79; German Standard DIN 2615; Japanese Standard JIS B2316; Chemical Standard SH3408, SH3409; Mechanical Standard HG/T21635 and so on. | ||
| Surface treatment | Pickling and passivation | use acid to remove surface oxidized skin and impurities, and then passivation treatment to form a passivated film to enhance corrosion resistance, such as pickling with a mixture of nitric, passivation with chromic acid or nitric acid | |
| Polishing | Mechanical polishing can make the surface roughness reach Ra0.8-Ra1.6μm, electrolytic polishing can reach Ra0.2-Ra0.4μm, make the surface more smooth and beautiful, reduce the resistance of fluid. | ||
| Paint spraying, plastic coating | spray paint can choose epoxy paint, polyurethane paint, etc., plastic coating can be used polyethylene, PTFE and other plastics, the thickness of the coating is generally in the range of 0.1mm-0.5mm, to play the role of anticorrosion, insulation and so on. | ||
| Processing precision | Roundness | when the outer diameter is less than DN100, the allowable deviation is ±0.5%; when the outer diameter is greater than or equal to DN100, the allowable deviation is ±1%. | |
| Straightness | the deviation of straightness per meter length is not more than 1mm-2mm, such as DN200 tee with 2m length, the deviation of straightness is not more than 4mm. | ||
| Port perpendicularity | the deviation of perpendicularity between the port and the axis is controlled at ±0.5°-±1° to ensure the sealing of the connection. | ||
