Butt Weld Straight-through Intermediate Joint
Core Function & Application Positioning
This straight welded joint adopts a butt weld straight-through structure, used for straight extension of two sections of welded pipelines with an equal-diameter non-reducing design and a pressure loss of ≤0.05MPa, with firm welds and excellent pressure resistance, suitable for high-pressure fixed pipeline extension in industries such as petrochemical and metallurgical, and can be used for a long time in high-temperature working conditions. The straight welded joint extends high-pressure pipelines.
Material & Craftsmanship
The joint is seamlessly forged with 304/316 stainless steel. Both ends of the joint are beveled and form an integrated structure with the pipeline after welding. The valve body is solution-treated to improve corrosion resistance. The weld has passed X-ray non-destructive testing with no welding defects and can withstand high temperatures of 425℃, ensuring the high-temperature resistance of the straight welded joint.
Specification Advantages
All specifications cover conventional pipe diameters from DN15 to DN200, are compatible with national and American standard butt weld standards, adapt to industrial pipelines with different pressure levels from 1.6MPa to 60MPa, support customized duplex stainless steel materials, and can provide welding process guidance.
Summary
The equal-diameter non-reducing of this straight welded joint ensures stable pipeline flow. The solution treatment improves corrosion resistance. The X-ray detection ensures weld defect-free. Its multi-standard adaptability can dock various industrial pipelines, and the welding process guidance can also improve on-site welding quality.
