Butt Weld Crosses — Equal & Reducing, ASME B16.9
A butt weld cross is a four-way fitting that joins one line to three others at 90°. Teshi Group manufactures equal and reducing crosses to ASME B16.9 in carbon, low-temperature, alloy and stainless steels, matched to your pipe schedule.
Also called: 4-way cross, buttweld cross, equal cross, reducing cross, pipe cross
What are Butt Weld Cross?
A cross has four openings — two in line on the run and two opposite branches at 90°. Equal crosses have all four ends the same size; reducing crosses have smaller branches. Crosses are welded on all four ends. Because four flows meet in one body, a cross sees higher stress at the intersections than a tee, so many piping specifications limit its use to services such as firewater and utility distribution, and use tees elsewhere.
Key features
- Equal and reducing crosses per ASME B16.9
- Four bevelled ends to ASME B16.25
- Wall thickness matched to the pipe schedule
- Saves space where four lines meet

FAQ
Butt Weld Cross: common questions
When should a cross be used instead of two tees?
Use a cross where four lines must meet at one point and space is limited. Two tees spread the junction out and are often preferred in process service because they reduce stress concentration.
Is a cross allowed in all piping specifications?
Not always. Some project piping specifications restrict crosses to utility or firewater service and require tees in process lines. Check the piping class or branch table before ordering crosses.
Are reducing crosses available?
Yes. Reducing crosses with branches smaller than the run can be supplied in the run and outlet size combinations tabulated in ASME B16.9, with the wall matched to each pipe schedule.
What documents are supplied?
An EN 10204 3.1 mill test certificate and a dimensional inspection report come as standard. EN 10204 3.2 or third-party inspection and IBR certification are provided when the order specifies them.
