Quick-closing door, 3-part bayonet

Overview

Maschinenbau Scholz Quick closing door, bayonet 3-parts is described as safe, durable and technically precise, designed according to the latest technological standards and fulfilling all safety requirements 100 %. At the customer's request the quick closing doors are available with fully automatic operation and the modular design is stated to guarantee maximum flexibility. The product family is presented as compact, completely pre-assembled for welding or screwing and suitable for the toughest applications in rough environments for a particularly long time. Advantages listed include a quick opening/closing system for the shortest possible operating times; customised design with adaptation to diameter, length, pressure, temperature, material and acceptance regulations; modular construction; proven and easy-to-maintain design for durability and reliability; and a principle proven for over 100 years. Multiple specific configurations are provided. Examples include: DN550 for vertical pressure vessel — Pressure: 4bar, Temperature: 0-50°C, Diameter: i. ⌀550, Material: 1.4301, Version: AD-2000; PED 2014/68/EU; 3-parts, with shell section, manual operation. DN575 for vertical pressure vessel — Pressure: 200bar, Temperature: 0-300°C, Diameter: i. 575, Material: P420QH, Version: AD-2000; PED 2014/68/EU; 3-parts, cover ring with welded spherical bottom, manual operation. DN800 for horizontal pressure vessel — Pressure: 50 bar, Temperature: 0 - +50°C, Diameter: i. ⌀800, Material: P250GH, Version: AD-2000; PED 2014/68/EU; ATEX-RL 2014/34/EU; 3-parts, flat cover, manual operation. Additional sample configurations include DN1200 (Pressure: 0 - 25bar, Temperature: 0 - +225°C, Diameter: i. ⌀1200, Material: 1.4571; P355QH, Version: AD-2000; PED 2014/68/EU; 3-parts, cover ring with welded dished plate, hydraulic/manual operation, hinge) and DN5000 (Pressure: -1 - 6,5 bar, Temperature: 0 - +170°C, Diameter: i. ⌀5000, Material: P355QH1; P265GH, Version: AD-2000; PED 2014/68/EU; 3-parts, cover ring with welded dished plate, hydraulic operation, hydraulic hinge). Various other sizes and combinations are listed, showing a range of pressures, temperatures, materials and actuation modes (manual, pneumatic, hydraulic, electric) and certifications (e.g. EN 13445; ASME Sect. VIII Div.1 Edition 2017/2019 with U-Stamp) in specific entries. The quick closing doors are intended to provide the shortest possible operating times through a quick opening/closing system and to ensure convenient loading and unloading by making the entire cross section of the pressure vessel freely accessible. Opening options are explicitly oriented to containers arranged horizontally, vertically or at an angle. The product family is presented for use where maximum flexibility in diameter, pressure, temperature and material compliance is required, and specific entries note suitability for rough environments and heavy-duty applications.
