標題: 這個是什么三通？怎么翻譯？
在一張國外圖紙里看到一串英文，不知道怎么翻譯？咨詢了很多人，大家也不知道這個是什么？

Barred reduce tee，這個如何翻譯？是管道里用的，好像是什么三通？

Reducing tee with rod 帶桿異徑三通
百度翻譯的，我理解是帶柵條網的變徑三通

Tee or Tee connection in piping engineering is a very important pipe fitting and is frequently used to combine or divide a flow. Two types of Tee are available, Equal Tee and Reducing Tee. However, in pigged pipelines, one special type of tee connection is widely used which is known as Barred Tee or Pigged Tee. In this article, we will try to study a few points about Barred Tee and Tee Connections.

Typical Tee and Barred Tee Connection
Tee vs Barred Tee

Tee is a type of fittings that allows fluid to flow on its main pipe and branch out. The branch can be designed equally the same size as the main pipe (known as Equal Tee), or smaller size than the main pipe (known as Reducing Tee).

Barred Tee is a special type of Tee that is based on a normal tee (can be either an equal tee or a reducing tee) that at a later stage, will be added with bar plates inside the branch outlet (From inside it looks like a steel cage) to restrict the pig from flowing from the header pipe into the branch pipes.

Design Codes and Standards for Tee and Barred Tee

The international standard dimension of the tee will be covered under ASME B16.9 or MSS-SP 75 (for DN16 and above). Click here to know more about Tee Connections.
There is no international standard dimension for the barred tee. It is custom-made using the ASME B16.9/ MSS-SP 75 tee as a base. However, many develop their barred tee based on Shell DEP 31.40.10.13-Gen or ISO 15590-2 standard.
This design can be a guideline to assess Vendor’s design.

Difference Between Tee and Barred Tee

So from the above discussion, we can summarize the following differences:

Parameter	Tee	Barred Tee
Definition	Standard Pipe Fitting	A special type of piping component
Manufacturing	Generally by Extrusion or forging	Mostly Fabricated
Use	Used in both piping and pipeline engineering	used in pipeline engineering near the pig launcher/receiver
Design Code / Standard	ASME B 16.9/MSS SP 75	Shell DEP 31.40.10.13-Gen or ISO 15590-2
Production Quantity	Large scale in bulk	Select small quantities (custom-made)
Cost	Cheaper	Costlier than normal Tee

過球三通

管道通球試驗和清管時，過球三通（又名檔條三通、清管三通、格柵三通）可以防止卡球事故和引導清管器順利通過主管線。按照管件口徑分一般有等徑三通，異徑三通等。按照支管方向分有正三通和斜三通。

有道翻譯翻譯成“禁止異徑三通”，就更不明白這是什么三通了。
