Steel Tee is a pipe fittings in the shape of a T with three branches. It typically, it comes in two forms: the Equal Tee or stainless steel reducing tees (Tee reducer) Both are used to split (combine) pipes in order to regulate the flow rate and alter the direction of flow.
Steel pipe tee can extensively used in various industries, and according to the materials types, which include:
Tee in stainless steel
Carbon steel tee
Alloy steel tee
Based on connecting types, they are:
Butt weld the tee
Socket Weld Tee
Threaded t-shirt
We know that steel tee comes in many varieties, but how many is there to know every kind of Tee? What is the best way to differentiate them and choose the most appropriate one that you require?
Below, we’ll provide additional specifications.
The Equal Tee is a steel reducing Tee.
Fittings for steel Equal Tee pipes Three branches of tee are the same in diameter.
Steel Reducing Tee/Reducer fittings for tee pipes The branch’s diameter is less than that of the primary line. Tee reducers are typically defined as NPS sizes of 4″ 4″ 3″ 3″ is the main line pipe’s diameter while the 3″ is the diameter of the reducing branch.
Reduced tees are used more often than a tee of equal size since it performs more functions and is it is suitable for a wider range of environments.
Butt Weld Tees – Socket Weld Tee Threaded Tee
Butt Weld Tee (BW Tee)
Ends are plain or beveled configuration, joined via butt welding. It can be more prone to pressure than other connection types. The dimensions of the socket weld tee must be stated in the pipeline NPS (DN) and the thickness of the schedule, in which the socket weld tee is threaded or tee’s thickness is defined in the pressure class ratings.
Socket Weld Tee (SW Tee)
As with other fittings for sockets have an area that is ladder-shaped that allows you to insert the pipe inside the tee branches and then join to. It is usually used to connect small dimensions tubing.
Threaded pipe Tee (THD Tee)
Based on SW tee designs that the branch ends will be threaded either the male or female. Therefore, there is a male with female branches in the case of a tube that has male NPT threads, the tee will have the female threads of NPT.
Tees made of stainless steel. Standard material
Tees made of stainless steel are used extensively in the chemical, sanitary, or food industries.It’s benefit is that it’s appropriate for various working environments and has a high resistance to corrosion.
The standards are: ASTM A403 (For wrought Austenitic stainless steel pipe fittings for tee pipes), ASTM A270 (For seamless and weldable Austenitic as well as Ferritic stainless steel tubing for sanitary use)
Grades: TP304, the 304L, 316 317, 310, and 321.
Steel pipe made of carbon and alloy Standard material
Carbon steel Tee materials: ASTM A234 WPB, WPC; MSS SP 75 WPHY-42 (WPHY 46, WPHY 52), 60, 65, WPHY-56 and 70. ASME/ANSI B16.9 for BW tee fittings and ASME/ANSI B16.11 for socket welds and threaded fittings for tees.
Alloy steel material: ASTM A234 WP1, WP5, WP9, WP11, WP22, WP91
With the help of cladding technology, you can create a cladding of stainless steel or alloy steel within the outer surface in carbon steel. is a different option to achieve a certain level of resistance to corrosion and reduce the cost of materials.
How do I make steel tees?
The most common manufacturing processes used for making tees is hot pushing and cold extrusion. Cold extrusion is usually used to make a thinner tees, while hot pushing is used for tees with a large size. If you require a large diameter tee that is larger than 24″ it is recommended that welding be the preferred method instead of extrusion.
The primary method to create steel tees is to make use of an hydraulic device to compress the mother pipe inside an tee mold (or the reducing tee mould) and, with the huge pressure at both ends of the pipe and three branches of the tee be extruded. The mother pipe can be a seamless or weld pipe. The same diameter pipe will make the same size tee. This so to produce an 8 inch steel tee you require a 8-inch pipe. However, after extrusion the thickness of the pipe will increasing, so that the thickness of the tee will be greater than the thickness of the mother pipe.
Equal Tee, Reducing Tee dimension the range
For butt welding tee dimensions are available in 1/2″ 1″ 1″, 1 1/2″ 2 3″ 4″ 6″ 8″ 10″ 12″ 14″ 16″ 16″, 24″ with a maximum of up to 48″ (From DN 15 to DN 1200). The thickness class ranges from SCH 10to 20 to SCH 40 and SCH STD. 80, SCHXS and 160 SCH.
For socket weld tees and threaded tee , dimensions vary from 3/8″ to 1/2″. 3/4″ 1″ or up to” (From DN 10 to DN 100). Pressure ratings of 2000# 3, 6000#, 3000##, and 9000#.
