Butt-welding isometric cross is a pipe connector, the main pipe and branch pipe is 90 ° perpendicular to the intersection of the four ports of the same diameter, used in the pressure piping system to achieve multi-directional isometric flow body diversion.
American butt weld straight cross (Equal cross)
- Certification requirements: ISO 9001 quality management system and industry-specific certifications (such as API 5L) are required.
- Matching pipeline material: ensure that the four-way and pipeline materials are consistent, to avoid galvanic corrosion.
- Working condition adaptability: give priority to alloy steel or duplex stainless steel for high temperature environment.
- Butt-welding connection should ensure that the bevel angle (37.5°±2.5°) and root clearance (1.6-3.2mm) in accordance with ASME B16.25 standards, to avoid welding deformation.
- High-pressure systems (e.g., Class 900 and above) require XXS wall thicknesses or customized thickened designs and verification of burst pressure test reports.
- Low-temperature environments (<-29°C) require Charpy V-notch impact-tested materials and compliance with ASME B31.3, Low-Temperature Piping Code.
- Provide Material Test Reports (MTR), heat treatment records and third party test certificates (e.g. DNV/ABS).
| Nominal Diameter (in.) | SCH40 weight (kg) | SCH80 weight (kg) |
| 2″ (DN50) | ~3.5 | ~6.2 |
| 6″ (DN150) | ~25 | ~45 |
| 12″ (DN300) | ~120 | ~220 |
| 24″ (DN600) | ~580 | ~1050 |

Specific weight should be calculated in combination with wall thickness (e.g. SCH grade) and material density.
Stainless steel tees weigh approximately 1.03 times as much as carbon steel (density difference).
