Purchasing Guide

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

  • For procurement requirements that require the use of sealed doors, it is recommended to prioritize checking key technical parameters such as door thickness, sealing level, and pressure resistance value to ensure that they match the protection requirements of factory buildings, laboratories, and other scenarios.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers usually have more stable delivery capabilities in the industrial explosion-proof or clean room fields.
  • In the application of chemical or pharmaceutical industries, the corrosion resistance and fire resistance of the material of the airtight door need to be the key evaluation items, and stainless steel or special coating door bodies are more suitable for high-frequency disinfection environments.
  • Different installation scenarios may affect the structural selection of airtight doors, such as waterproof design for underground facilities and insulation layer configuration for high-temperature workshops.

Knowledge Base

Q

Waterproof sealing door is a protective door with dual functions of waterproofing and sealing. It is mainly made of steel or composite panels, matched with rubber sealing strips and pressure locks. Capable of withstanding a certain amount of water pressure, preventing water and gas infiltration, and suitable for scenarios such as basements, underground garages, and mines. It has the characteristics of stable structure and flexible opening and closing, which can ensure space safety and prevent water immersion or harmful gas invasion.

Q

Overview of Explosion proof Sealed Doors Explosion proof airtight door, also known as chamber isolation door, is an important component of the refuge chamber. The gear linkage locking mechanism of the explosion-proof airtight door is insulated and sealed, with an impact resistance of ≥ 0.3MPa. The YH/FBM1000 series explosion-proof sealing door produced by our company is easy and fast to open, with safe and reliable sealing, easy to install, and has an impact resistance of not less than 1.0

Q

A sealed door is a type of door with good sealing performance that can isolate indoor and outdoor environments, preventing external factors such as gas, moisture, noise, and dust from entering. It plays an important role in laboratories, clean rooms, hospital operating rooms, and other places, providing people with safer, more comfortable, and private spaces.
