It connects pipes of the same diameter. The branch direction of the pipe is perpendicular to the main pipe. The wall thickness range is SCH5S-XXS. For seamless tee fittings, the size range is 1/2”–24” (DN15–DN600), and for welded tee fittings, the size range is 1/2”–48” (DN15–DN1200). It is made of carbon steel, stainless steel, duplex steel, or special alloy steel. What Is a Buttweld Equal Tee? A Buttweld Equal Tee is a type of pipe fitting used to divide or combine fluid flow in industrial piping systems. All three outlets of an equal tee have the same diameter, ensuring smooth and balanced flow distribution. This fitting is widely used in industries such as oil & gas, petrochemical, power generation, shipbuilding, water treatment, and mechanical engineering. If your project requires precise flow management, durability, and secure welded connections, a buttweld equal tee is the ideal solution. Buttweld equal tee fittings have the same diameter in all three ports, whereas reducing tees often have two branches with the same diameter and one branch with a different diameter. buttweld equal tee Carbon Steel Equal Tee Material Grades: Stainless Steel Equal Tee Material Grades: ASTM A234 WPB ASTM A403 WP316/316L ASTM A420 WPL6 ASTM A403 WP304/304L A860 WPHY42 ASTM A182 F316L, 304L ASTM A860 WPHY 52 DIN 1.4301 ASTM A860 WPHY 60 DIN1.4306 ASTM A860 WPHY 65 DIN 1.4401 Available in Multiple Standards We supply Buttweld Equal Tees in: ASME B16.9 ASTM A234 WPB / WPC / WP11 / WP22 ASTM A403 WP304 / WP316 EN10253 / DIN2605 / JIS B2311 Buttweld Equal Tee Dimensions Buttweld Equal Tee Dimensions Nominal Pipe Size Outside diameter at bevel Center-to-End Run (C) Outlet(M) 1/2″ 21.3 25 25 3/4″ 26.7 29 29 1″ 33.4 38 38 1 1/4″ 42.2 48 48 1 1/2″ 48.3 57 57 2″ 60.3 64 64 2 1/2″ 73.0 76 76 3″ 88.9 86 86 3 1/2″ 101.6 95 95 4″ 114.3 105 105 5″ 141.3 124 124 6″ 168.3 143 143 8″ 219.1 178 178 10″ 273.0 216 216 12″ 323.8 254 254 14″ 355.6 279 279 16″ 406.4 305 305 18″ 457.0 343 343 20″ 508.0 381 381 22″ 559.0 419 419 24″ 610.0 432 432 The dimensions are in millimeters Source : ASME B16.9 – 2007 Note: Seamless steel pipes can be processed into seamless pipe fittings, which do not require welding and have no welds. They have better sealing and pressure resistance, and are suitable for high-pressure, high-temperature, or systems with higher sealing requirements. Generally, fittings made from steel plates are welded fittings, which are formed by joining and welding the edges of the steel plates. During the welding process, a weld seam is formed at the joint. This manufacturing process is relatively simple and suitable for general low-pressure piping systems. Applications of Buttweld Equal Tee Our Buttweld Equal Tees are commonly used in: Oil & Gas Pipelines Chemical Processing Plants Boiler & Pressure Vessel Systems Water Supply Systems Shipbuilding & Offshore Engineering Power Generation Plants These buttweld tees ensure efficient flow distribution, making them vital components in both high-pressure and high-temperature environments.

In industrial machinery, automotive systems, and countless mechanical assemblies, oil seals play a quiet yet decisive role. They are the guardians of lubrication, preventing leakage while keeping contaminants away from sensitive components. Although their function may sound straightforward, the diversity of oil seal designs reflects the complexity of modern engineering needs. Radial Shaft Seals Perhaps the most recognized category, radial shaft seals are designed to protect rotating shafts. Their flexible lip maintains contact with the shaft surface, ensuring oil remains inside while dust and moisture stay out. These seals are widely used in gearboxes, pumps, and engines, where consistent rotation demands reliable sealing performance. Hydraulic and Pneumatic Seals Hydraulic systems rely on seals that can withstand high pressure and fluid dynamics. Hydraulic oil seals are built to resist extrusion and wear, ensuring cylinders operate smoothly. Pneumatic seals, though similar in principle, are tailored for air-driven systems, emphasizing low friction and durability. End Cap Seals End cap seals are used when a shaft opening needs to be completely closed. Instead of allowing rotation, they act as a barrier, blocking oil passage and protecting the housing. This type is common in applications where unused shaft holes must be sealed securely. V-Ring Seals V-rings are elastic seals that fit directly onto the shaft. Their flexible design allows them to act as a flinger, deflecting dirt, water, and other contaminants away from the sealing area. They are often paired with radial seals to provide an additional layer of protection in harsh environments. Axial Seals Unlike radial seals, axial seals are positioned to work against a flat surface. They are frequently used in rolling bearings and other assemblies where axial movement requires a tight yet adaptable sealing solution. Customized and Application-Specific Seals Beyond standard categories, many industries demand seals tailored to unique conditions—high temperatures, aggressive chemicals, or extreme speeds. Manufacturers develop specialized oil seals with reinforced materials, multi-lip designs, or advanced coatings to meet these challenges. Oil seals are not a one-size-fits-all solution. From radial shaft seals to specialized designs, each type addresses a particular mechanical challenge. Understanding these categories helps engineers and procurement professionals select the right seal for their equipment, balancing durability, efficiency, and cost-effectiveness.
