The steel pipe tee is the most common piece used when there is a branch on the main pipeline. When the size of the branch is the same as the header pipe the equal tee is used. When the branch size is less than the header size unequal tee is used then. Currently, hydroforming and hot press forming are used to manufacture steel tee made of seamless pipe. The steel pipe tee is used to connect pipelines in networks to transport two-phase fluid mixtures. It can be stored in fumigation-free boxes or wooden holders.
Our company provides steel pipe tee of different sizes such as 1/2″ and 24″, DN15 and DN600 seamless fittings, 4″ and 24″, DN100 and DN600 weld fittings or 12″ and 78″, DN300 and DN1900 butt welding fittings. There is also different wall thickness. The maximum wall thickness of the steel pipe tee is 150 mm and other schedule numbers are sch10, sch20, sch30, enfermedad de transmisión sexual, sch40, sch60, xs, sch80, sch100, sch120, sch140, sch160, xxs, sch5s, sch20s, sch40 y sch80.

Pipe Tee Sytle:
Pipe tee is used for distributing or collecting the fluid from the run pipe. It is a short piece of pipe with a 90-degree branch at center. There are two types of Tee used in piping, Equal / Straight Tee and Reducing / Unequal Tee.
Straight Tee
In straight tee, the diameter of the branch is same as the diameter of the Run (Header) Pipa.
Reducing Tee
In reducing tee, diameter of the branch size is smaller than the diameter of the Run (Header) Pipa
Barred Tee
A barred tee which is also known as a scrapper tee is used in pipelines that are pigged. The branch of the tee has a restriction bar welded internally to prevent the pig or scrapper to enter the branch. The bars are welded in the branch in a way that it will allow restriction free passage of the pig from the run pipe.

TEES straight and reducing
The primary purpose of a Tee is to make a 90° branch from the main run of pipe. Standard there are 2 possibilities, on behalf of the equal tee and reducing tee. The equal tee (or straight tee) is used as the branch has the same diameter as the run-pipe. The reducing tee is used as the branch has a smaller diameter as the run-pipe.
Dimensions and Standards
When we talk about a tee NPS 3, a equal or straight tee is intended. With a tee NPS 3 incógnita 2 a reducing tee is intended. Although, officially a reducing tee will be indicated by 3 diameters, namely 3 incógnita 3 incógnita 2 (A x B x C). The A and B measure stands for the Nominal Pipe Size of Run-Pipe, C measure stands for Nominal Pipe Size of Outlet.
This designation actually is superfluous, but comes from the time that tees were available in 3 different ends of diameters, como
4 incógnita 3 incógnita 2 (A x B x C). In this implementation of course it is necessary, to specify 3 different sizes.
That kind of tees is probably no longer available. Applying a equal tee with a concentric or eccentric reducer is now the usual practice.
A straight or equal buttwelding Tee is available for all common diameters.
A Reducing Tee not, because many diameters are not produced, or can not be produced.
As an example: a reducing tee NPS 6 incógnita 4 is a standard item for most suppliers, but a reducing tee NPS 16 incógnita 2 is probably not available by any supplier.
It would also not economical to use a NPS 16 tee with a NPS 2 outlet; in such situations a Branch Fitting will be used or a Branch Connection will be made.
In addition to the defined tees, there are straight and reducing crosses.
Straight crosses are generally stock items, reducing crosses are often difficult to obtain.
I have never used that tees and I have they never seen in practice, at least not in petro and chemical industry. They will be used where space is limited, by revision work, in shipping industry et cetera.
Wall thickness Tee
By the shape of a tee, the wall thickness can be a critical item. ASME B16.9 only standardizes the end-to-end dimensions, center-to-end dimensions and some “squareness” dimensional tolerances.
The wall thickness at the weld line location even is standardized, but not through the rest of the fitting. The standard states that the minimum tolerance will be within 12.5% of the minimum ordered wall thickness of the pipe. A maximum tolerance is specified only at the ends of the fitting.
Many providers of welding tees (and elbows) provide one schedule greater thickness so that sufficient wall thickness, after forming, remains. In Tee’s, the crotch radius (t) varies from one manufacturer to another, but some establish itself as a requirement, 1.3 times the wall thickness to maintain the crotch.
