SA-335 P11 · 1¼Cr-½Mo alloy pipe
An ASTM A335 P11 cross is a four-way fitting with branches at 90°, for use with ASTM A335 P11 pipe. ASTM A335 P11 itself is a pipe or plate specification, so the matching cross is made to ASTM A234 WP11 (buttweld) · ASTM A182 F11 (forged) — which is what we supply for P11 lines. Crosses join four pipes in one fitting. They are used less than tees because of stress concentration, but save space in fire-water and utility systems.

Why are crosses less common than tees?
They concentrate stress at four junctions; most designers use two tees unless space is critical.
Which standard covers ASTM A335 P11 crosss?
The material is ASTM A234 WP11 (buttweld) · ASTM A182 F11 (forged); dimensions follow ASME B16.9 · B16.11. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a ASTM A335 P11 cross?
The steel price, the size and schedule or class, quantity, and the testing and documents required. Send your list and we quote the same working day.
What documents do you supply?
EN 10204 3.1 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
