Welded Straight-through Union Joint
Core Function & Application Positioning
This union welded joint adopts a welded straight-through union design, with both ends as welded interfaces and a union structure in the middle, realizing quick disassembly and maintenance of welded pipelines without cutting the pipeline, suitable for industrial pipelines requiring regular maintenance such as chemical medium transmission pipelines. The union welded joint facilitates pipeline maintenance.
Material & Craftsmanship
The joint is forged with 304/316 stainless steel. The union part adopts spherical sealing with a sealing grade of API 607 standard. The welded end is beveled, and the union nut is anti-loosening treated. The joint has passed an air tightness test without leakage and can withstand strong corrosive media, ensuring the sealing of the union welded joint.
Specification Advantages
All specifications cover conventional pipe diameters from DN15 to DN100, are compatible with national and American standard welding standards, adapt to pipelines with different pressure levels from 1.6MPa to 40MPa, support customized duplex stainless steel materials, and can provide maintenance and disassembly guidance.
Summary
The union structure of this union welded joint realizes quick pipeline maintenance. The spherical sealing ensures zero leakage. The anti-loosening nut improves stability. Its multi-standard adaptability can dock various industrial pipelines, and the maintenance guidance can also simplify the disassembly and assembly process.
