Seamless steel 90-degree butt-weld elbows are used for right-angle turns in process piping, maintaining a continuous flow path and ensuring reliable welded connections. They are commonly used in the petroleum, chemical, power generation, and district heating industries, as well as in pressure piping systems.
Wyprodukowane przy użyciu zaawansowanego sprzętu CNC i sprawdzonych procesów, nasze kołnierze, zagięcia rur i złączki zapewniają dokładne wymiary, stabilną wydajność uszczelniania i niezawodną instalację w wymagających zastosowaniach przemysłowych.
Normy: GB/T 12459-2025, GB/T 13401-2025; ASME B16.9-2024 ma zastosowanie do projektów eksportowych.
Configuration/Dimensions: 90° long radius (standard) or short radius; specify bending radius, center-to-end dimension, and wall thickness; ASME B16.9 covers NPS 1/2–48 (DN15–1200), with wall thickness determined by the connected piping Schedule (Sch) or design thickness.
Connection: Butt-weld; bevel configuration and root face dimensions are to be confirmed based on welding procedures and project specifications.
Material: Carbon steel, stainless steel, or alloy steel; material grade, seamless/welded type, heat treatment, and NDT requirements must be clearly specified at the time of inquiry.
Pressure Rating: Butt-weld fittings typically do not carry a standalone “Class” rating; pressure-bearing capacity is determined by material, wall thickness, temperature, and applicable piping design codes.
Ordering/Acceptance: Confirm NPS/DN, port diameters, wall thickness/Sch, dimensional configuration, seamless/welded type, material grade, heat treatment, bevel details, and NDT requirements; pressure-bearing capacity is verified based on material, wall thickness, temperature, and piping design codes.
