Non-standard elbows are mainly used in pipeline turns, spatial avoidance, equipment connection, and pipeline network renovation projects where standard pipe fittings cannot be adapted. Unlike standard elbows, their bending angle, bending radius, nominal diameter, wall thickness, groove form, and end face form can all be re-determined according to customer drawings or on-site dimensions, making them more suitable for working conditions such as old equipment renovation, imported unit connection, piping in narrow spaces, and special-shaped pipeline routing. Forming processes include seamless hot pushing, steel plate rolling, bending, die forming, and forging; material options include carbon steel, stainless steel, low-temperature steel, alloy steel, duplex steel, and nickel-based alloy. We can arrange heat treatment, non-destructive testing, sandblasting, pickling and passivation, and anti-corrosion coating according to the working conditions, and provide material certificates, inspection reports, and factory inspection documents as needed. Before purchasing, it is recommended to provide drawings or on-site dimensions, angle, radius, installation distance, material, and quantity; we will assist in confirming the structure, process, and quotation.

| Packaging | Non-standard elbows adopt a customized export-exclusive refined packaging solution, with targeted protection according to product size, special-shaped structure, wall thickness differences, and sea/land transportation requirements, eliminating problems such as deformation of special-shaped parts during transportation, bevel collisions, surface scratches, and rust contamination. Small precision special-shaped non-standard elbows use pipe-end protective caps, full bubble wrap, waterproof film sealing, and separate carton packing to avoid mutual extrusion and abrasion of special-shaped structures. Medium non-standard bends and special-shaped pipe fittings with straight sections use multi-layer wrapped waterproof and anti-rust film and shockproof bubble wrap, arranged neatly by category to eliminate displacement and collisions during transportation. Large-diameter ultra-large-radius, ultra-long special-shaped, and heavy thick-wall non-standard elbows use overall rainproof cloth wrapping, solid wood pallets at the bottom for load-bearing fixation, and overall steel strap reinforcement to prevent distortion and deformation during long-distance sea transportation. |
