LIANHE is a China stainless steel fitting manufacturer supplying the Stainless Steel Groove Tee for wholesale and custom procurement projects worldwide. Buyers looking to purchase grooved pipe fittings in bulk can request a factory quotation directly, with sizes from 2" to 8" (DN50–DN200), wall thickness from 1.0 mm to 5.0 mm, and materials available in SS304, SS316, SS304L, and SS316L.
This grooved tee is mechanically formed from stainless steel pipe and connected through a grooved joint, providing a reliable branch connection for water supply, HVAC, marine, and industrial piping systems. Each piece is pressure-tested and inspected before shipment, and custom markings, packaging, and inspection documents can be arranged according to the confirmed purchase requirements.
This grooved tee uses a mechanical grooved joint that simplifies installation, reduces on-site welding, and allows convenient inspection, maintenance, and replacement during service.
Formed from 304, 316, 304L, or 316L stainless steel pipe, the fitting provides excellent corrosion and oxidation resistance for water, chemical, and marine applications.
The mechanically formed body keeps the internal surface smooth, minimizing flow resistance and supporting consistent media transfer across the branch connection.
With a nominal pressure of PN16, hydrostatic test pressure of 2.5 MPa, and airtightness test pressure of 1.05 MPa, the Stainless Steel Groove Tee delivers dependable sealing under working conditions.
For drinking-water and sanitary systems where permitted, this fitting supports hygienic piping requirements and carries a Sanitary License for applicable configurations.
Product marking follows the LOGO–OD–W.T.–Material format, and customer logos, private brands, batch information, export cartons, and wooden cases can be arranged on request.
The product is mechanically formed from seamless or welded stainless steel pipe, giving it high mechanical strength and structural stability under pressure, vibration, and thermal cycling. The grooved joint maintains a firm connection that resists deformation and wear during long-term operation.
Because the body is made from stainless steel rather than coated carbon steel, the fitting resists corrosion and oxidation in humid, chemical, and marine environments. This extends service life and reduces the need for frequent replacement or repainting.
Grooved connections allow this grooved tee to be installed quickly without extensive on-site welding. This reduces labor time, lowers installation cost, and makes future inspection, disassembly, and maintenance more convenient compared with fully welded joints.
When the correct gasket is selected and the groove profile matches the mating pipe, the fitting provides a dependable seal with reduced leakage risk. Gasket temperature range covers -20°C to +110°C for standard configurations.
Stainless steel is a hygienic, recyclable material suitable for drinking-water pipelines where permitted. This product therefore supports both sanitary requirements and sustainability goals in modern piping projects.
Buyers can specify size, wall thickness, material grade, groove profile, gasket material, surface treatment, marking, and packaging. LIANHE supports OEM and project-based procurement with coordinated production and documentation.

The actual working pressure and temperature limits depend on product size, wall thickness, stainless steel grade, gasket material, transported medium, groove dimensions, and applicable project requirements. Buyers should confirm these parameters before placing a purchase order.
This grooved tee can be supplied for use with compatible liquid and gaseous media, including drinking water, cold water, hot water, wastewater, industrial water, oil and compatible liquid media, and gas or compatible gaseous media.
Material and gasket compatibility should be confirmed according to the transported medium, operating temperature, system pressure, chemical conditions, and required service life. For drinking-water, gas, oil, steam, or other specialized applications, additional testing, certification, or project-specific documentation may be required.
The fitting is used in engineering and infrastructure projects, marine piping installations, commercial and residential buildings, hospitals, hotels, public facilities, environmental protection equipment, and water-treatment systems.
Typical installations include water supply lines, direct drinking-water pipelines, gas distribution systems, wastewater systems, steam systems, heating networks, air-conditioning pipelines, and industrial water systems. Before ordering, buyers should confirm outside diameter, wall thickness, groove profile, gasket material, working pressure, operating temperature, and the applicable dimensional standard.
Hydrostatic pressure test, airtightness test, working pressure test, negative-pressure test, pull-out test, cold- and hot-water temperature-cycling test, hydrostatic bending and torsion test, hydrostatic vibration test, and hydrostatic impact test. The applicable items and sampling ratio depend on the product specification, governing standard, intended application, and confirmed inspection plan.
Each order goes through standard delivery inspection covering stainless steel material grade, outside diameter and wall thickness, product dimensions and tolerances, groove dimensions and surface condition, hydrostatic performance, airtightness performance, product markings, quantities, and packaging. Additional items can be arranged on request.
In-process and final inspection procedures are applied throughout raw-material preparation, cutting, machining, forming, welding, heat treatment, surface finishing, testing, marking, and packaging. Products are approved for shipment only after completing the applicable inspection procedures.
