A234 Alloy Steel Tee is one of best Pipe Fittings for pipeline installation. Which forged by alloy steel with great hardness, heat and corrosion resistance. Mainly used at the branch point of the main pipe, which aims to change the direction of fluid or gas. It can be alloy steel equal tee and alloy steel reducing tee.

ASTM A234 Standard

ASTM A234/A234M is an American material standard which adopts by nations now. It includes specification of piping fittings of wrought carbon steel and alloy steel for moderate and high temperature service

AISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weld ability standpoint. The alloy can be hardened by heat treatment.

The AISI/SAE steel grades system is a standard alloy numbering systems for steel grades maintained by SAE International. In the 1930s and 1940s the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.

Pipe Tee Marking

To identify the tee easily for the users. There will be marking on the A234 Alloy Steel Tee. The content is including tee name, size, thickness or class, type, material, standard and heat number. “Equal Tee 4” Sch80, BW A234 WP91 ASME B16.9 Z168″ could be“ E.T 4” Sch80 A234 WP91 Z168” .When the size is too small to show all information, the size and heat number will be most important marking. “1/4” Tee SW A182 F22 6000# ASME B16.11 Z150” will be marked as 1/4” Z150”.
