application
- Specially designed for 180° pipe turns in extremely confined spaces, suitable for compact equipment layouts (such as internal piping of units and equipment interlayers).
- Used in situations requiring rapid backflow and with limited installation space, such as ship engine rooms, mobile pressure vessels, and modular chemical plants.
- Replaces long-radius elbow or multiple elbow combinations to minimize installation volume.
advantages
- Maximum space utilization: the quick turn round Ø 1.0D breaks through spatial limitations with an industry-best turning radius of 180°.
- The design based on full welded construction ensures zero-leakage, no-joint, making it equivalent to straight pipe in pressure bearing capacity.
- Expanded material compatibility: Carbon steel (S235/P235TR2) or stainless steel (WP304/WP316L equivalent), ideal for corrosive or clean environments.
- Increased installation efficiency: one-component replacement of multiple parts. more than 50% off the welding points, construction schedule reduction and labour costs saving.
- Surface reinforcement method: black paint protection, hot-dip galvanizing or acid washing passivation, improve weather resistance and service life.
packing
- Anti-deformation reinforced packaging:Customized wooden boxes + internal support frames are used to prevent U-shaped structures from deforming during transportation.
- Double port protection:High-strength engineering plastic plugs are installed on the pipe ports, covered with cushioning foam sleeves.
- Anti-rust core technology:The surface is covered with vapor phase corrosion inhibitor (VCI) film, suitable for the humid environment of sea transportation.
- Intelligent Identification System:Outer boxes are labeled with product name, angle type (short radius), dimensions, and a “Fragile Component” warning label.
