The steel pipe cross is used when there is a branch on the main pipeline that needs to be connected. When the size of the branch is the same as the header pipe equal cross is used and when the branch size is less than the header size, then, unequal cross is better. Our company applies hydroforming and hot press forming to manufacture steel crosses which are made of seamless pipe. Hydroforming can complete steel pipe cross shape forming at once, thus getting high efficiency.

Materials for making our pipe cross are often low carbon steel, low alloy steel and stainless steel to strain hardening tendency. However, if hot press forming technology is adopted and equipment required is of small tonnage. Besides, large diameter and large wall thickness steel cross are usually manufactured by means of hot press forming.

The maximum wall thickness of the steel pipe cross is 150 mm and some schedule numbers are sch10, sch20, sch30, std, sch40, sch60, xs, sch80, sch100, sch120, sch140, sch160, xxs, sch5s, sch20s, sch40s and sch80s. Our steel cross and related pipe fittings are widely used in electricity, gasoline, petrochemical, ship building, heat supply network, paper making and metallurgical industries among others.

CARBON STEEL BUTT WELD FITTINGS

• ASTM A234 Carbon steel Cross – Wrought Carbon and Alloy Steel Butt Weld Fittings : This specification covers wrought carbon steel and alloy steel butt weld fittings of seamless and welded construction. This is the most common material for carbon steel butt weld fittings (specifically grade WPB) and is seamless up to 24”, where diameters of 24” or larger may come seamless or welded.  These butt weld fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.
• ASTM A860: This specification covers wrought high-strength ferritic steel butt weld fittings of seamless and electric fusion-welded construction covered by the latest revisions of ASME B16.9 and MSS-SP-75.  These butt weld fittings are for use in high-pressure gas and oil transmission and distribution systems.

STAINLESS STEEL BUTT WELD CROSS FITTINGS

• Seamless and Welded Stainless Butt Weld CROSS FITTINGS: This specification covers the standard for seamless and welded wrought austenitic stainless steel butt weld fittings for pressure piping applications.
