Production Description

Steel pipe cross

ASME B16.9 Stainless Steel Butt Weld Cross Fittings is used where four pipes intersect. The cross pipe may have one inlet and three outlets, or three inlets and one outlet. The diameter of the outlet and inlet can be the same or different.

Equal cross

The equal cross is one kind of the pipe cross,  the equal cross means all the 4 ends of the cross are in same diameter.

Reducing cross

The reducing cross also is called unequal pipe cross , it is the pipe cross which the four branch ends are not in the same diameters.

Product features

  • It has corrosion resistance, high temperature ductility and low permeability.
  • Pipes commonly used to connect air, water, fuel, oil and inert gases.
  • A compression pipe cross uses compression fittings on two or more ends.
  • A wing pipe cross has lugs to fasten the fitting to a wall or stud.

Production Material

ASME B16.9 Stainless Steel Butt Weld Cross Fittings mean the pipe fittings which material is wrought austenitic stainless grade WP304L,they are used for the pressure piping systems of moderate and high temperature services.ASTM A403 is the standard of pipe fittings material,it indicates the materials properties of different kinds of stainless steel,WP304L is one of the steel grade in this standard.The corrosion resistance of 304L and 304 are similar.But after eliminate stress or welding,corrosion resistance of 304L will be more excellent.ASTM A403 WP304L is the most common stainless steel pipe fittings material.
