Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of flat gates, it is recommended to prioritize checking key technical parameters such as gate thickness, sealing grade, and pressure resistance range to ensure compatibility with the operating conditions of the pipeline or channel system.
  • In hydraulic engineering or sewage treatment scenarios, the material selection of flat gates needs to consider the influence of corrosive media. For example, stainless steel gates are suitable for high salt environments, while carbon steel gates are mostly used for ordinary clean water transportation.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to reduce procurement risks.
  • For high flow rate application scenarios, it is recommended to choose a flat gate with a diversion groove design to reduce the wear of the gate structure caused by water flow impact and extend its service life.

Knowledge Base

Q

Flat gate belongs to hydraulic metal structure products, and the manufacturer's strength directly determines the product quality. Choosing a manufacturer should not only compare prices, but also comprehensively consider production capacity, technical strength, project cases, and after-sales ability. Firstly, check the manufacturer's production qualifications, whether they have experience in the production and manufacturing of hydraulic metal structures, whether they can design and produce according to SL74-2019 standards, and whether large gates can be used

Q

The waterproofing principle of cast iron flat gate is mainly based on material, structural design, installation, commissioning, and maintenance. In terms of material, sealing components are usually made of materials with good sealing performance, such as rubber. Rubber has good elasticity and strong water resistance. When the gate is closed, the sealing component undergoes elastic deformation under pressure, filling the gap between the gate and the surrounding structure to prevent water leakage
