Products cover DN15–DN3000 diameters; processes are divided into three categories: seamless pressing, high-pressure forging, and large-diameter rolled welding; connection methods include butt welding, socket welding, and threading; surfaces can be acid-pickled and passivated, mirror-polished, or sandblasted.
Key Features
In terms of material, 304 and 316L are commonly used choices for conventional corrosive working conditions, while 904L, 2205, and 2507 are suitable for high-chloride, strong acid-base, or seawater environments. In terms of process, the seamless pressed type has smooth flow channels and few welds, suitable for small and medium-diameter clean pipeline networks; the forged type has dense grains, suitable for high-pressure and high-temperature equipment pipelines; the rolled welded type can achieve extra-large pipe diameters, filling the gap in mold specifications. In terms of surface treatment, acid pickling and passivation and mirror polishing can meet the requirements of high-purity fluid transportation for inner wall cleanliness. Connection methods cover butt welding, socket welding, and threading, making it convenient to match different pipeline designs and maintenance needs. The temperature resistance range can cover -196℃ to 650℃, with stable performance under alternating hot and cold working conditions.
Applications
In the chemical field, it can be used for fine chemical acid-base transportation, desulfurization and denitrification pipeline networks, and organic solvent circulation pipelines; in the pharmaceutical and food fields, it can be used for aseptic transportation, pure water purification, and beverage processing pipeline networks, requiring no metal precipitation and no contamination of the medium; in the marine engineering field, it can be used for seawater desalination, coastal salt spray pipeline networks, and offshore platform transportation pipelines, requiring resistance to chloride ion corrosion; in the energy field, it can be used for high-temperature steam in power stations, waste heat circulation, and high-temperature pipelines in new energy processes; in the environmental protection field, it can be used for industrial sewage, waste gas treatment, and corrosive wastewater transportation pipeline networks.

FAQ
What is the difference between stainless steel tees and carbon steel tees?
Stainless steel tees are more suitable for harsh working conditions in terms of corrosion resistance, cleanliness, and high-temperature resistance. Carbon steel pipe fittings are prone to rust in humid, acid-base, and salt spray environments, which may cause medium contamination or pipeline network blockage. Stainless steel material has its own passivation protective layer, which can resist acid-base, salt spray, seawater, and oxidation corrosion, does not rust during long-term operation, and does not peel, making it suitable for pipeline systems in chemical, pharmaceutical, food, marine engineering, and other fields that require cleanliness and corrosion resistance.
How to choose between 304 and 316L stainless steel tees?
For ordinary atmospheric environments or weakly acidic corrosion conditions, 304 or 304L can be selected. For seawater, high chloride ions, and strong acid-base fine chemical conditions, it is recommended to choose 316 or 316L, which has stronger corrosion resistance. If the medium is more corrosive or the temperature is higher, 321, 904L, 2205, or 2507 can also be considered. For specific selection, please provide the medium composition, concentration, and temperature, and we will assist in confirming.
How to choose among the three processes: seamless pressing, forging, and rolled welded?
For small and medium diameters under conventional corrosion conditions, the seamless pressed type can be selected, with smooth flow channels and few welds. For high-pressure and high-temperature equipment pipelines, the forged type is recommended, with dense grains and no welding defects. For extra-large diameter pipeline networks, the rolled welded type can be selected, enabling non-standard customization of larger diameters. If you are not sure which process to choose, welcome to contact us and provide the diameter, pressure, and temperature parameters, and we will assist in matching.
Can stainless steel tees be used in the food and pharmaceutical industries?
Yes. We can perform mirror polishing and sterile acid pickling and passivation treatment on stainless steel tees, making the inner and outer walls clean and free of impurities and free of oxide scale, meeting the requirements for high-purity fluid transportation. Food, pharmaceutical, and pure water purification pipeline networks usually use 304 or 316L material. For specific surface treatment grades and cleanliness requirements, please contact us to confirm.
What is the temperature resistance range of stainless steel tees?
The stainless steel tees we supply can withstand a temperature range of -196℃ to 650℃, with stable performance under alternating hot and cold and pressure impact conditions. The applicable temperature of different materials and processes will vary. If you have specific operating temperatures, welcome to contact us to confirm the suitable material and process.
