Frequently Asked Questions (FAQ)
What materials are typically used for blast-resistant door frames?
Door frames are typically made from channel steel or rectangular tubing. Class A frames use 50mm × 120mm × 4.0mm rectangular tubing, and Class B frames use 30mm × 120mm × 3.0mm rectangular tubing.
How thick should the door panel be for different blast pressures?
The required door panel thickness varies by pressure resistance: 5.0mm is used for 0.19 MPa pressure resistance, 4.0mm for 0.15 MPa, and 3.0mm for 0.11 MPa.
What are the standard sealing gap requirements for blast-resistant doors?
To maintain proper sealing performance, the gap between the door and the frame should be ≤ 10mm, and the contact gap from the door edge to the frame should be ≤ 5mm.
What type of hardware accessories are installed on these protective doors?
They are equipped with specialized pressure-bearing hinges and secure locking mechanisms, such as blast-resistant handwheel locks or emergency push bar locks.
Which industries and facilities require blast-resistant doors?
These doors are essential for chemical plants, the oil and gas industry, defense and ammunition depots, metallurgy and mining operations, and warehousing facilities managing hazardous materials.
What standards do these blast-resistant doors comply with?
