What is a Buttweld Equal Cross?
A Buttweld Equal Cross is a type of pipe fitting used to connect four pipes of the same diameter in a piping system, forming a cross shape. Each outlet of the cross is of equal size, allowing for uniform flow distribution and direction in all directions. This fitting is designed to ensure balanced fluid flow and pressure across the connected pipes, making it suitable for various applications in industries such as oil and gas, chemical processing, petrochemical, and others. The Buttweld Equal Cross is manufactured to meet industry standards like ASME B16.9 and is available in a range of sizes and materials to suit different piping requirements.

Buttweld Fitting Weights
ASME buttweld fitting specifications do not specify weights for fittings. Weights quoted in the table on this page are based on manufacturers information and should be considered as approximate and provided as a guide only (fitting weights can vary considerably between manufacturers due to differences in construction). Weights in these tables are taken from Hackney Ladish, Inc. Hackney Ladish, Inc. is one of the largest and most versatile fitting producers in the world. Hackney Ladish, Inc. is headquartered in Dallas, TX and operates 2 facilities containing 380,000 square feet of manufacturing.Dimensions Lap Joint Stub Ends schedule STD XS ASME B16.9
