Straight cross is a four-way fitting used to make double perpendicular connections to the pipe. It resembles a crossroad. Lines that connect to the main run of pipe are known as “branches”. The main run of pipe is often called the “header”. The word “straight” denotes that all four outlets are the same pipe size.
Standard & Materials:AISI 304/L
The SAE/ANSI 304 (AISI 304) is the most commonly available and used type of stainless steel. It is also referred to as 18/8 stainless steel, A2 stainless steel (as per the ISO 3506), or 304S15 (as per the British Standard). This is an austenitic chromium-nickel alloy which practically means that it has a very high corrosion resistance. It is also nonmagnetic and can’t be hardened through heat treatment. As AISI 304 can withstand extremely corrosive environments and can be shaped, machined and welded relatively easy, it is very popular for a wide range of applications.

NOTES:
- Patterns shall be designed to produce castings of metal thickness given in the Table. Metal thickness at no point shall be less than 90% of values given in the Table.
- The length of thread may extend beyond the width of band. However, minimum metal thickness (G) must be maintained at the end of the thread.
- Ribs are permitted as per Section 9. The applicable “external” broken lines in the drawings above indicate where ribs are allowed.
