Product Introduction:
ASTM A193 washers are high-performance fasteners used in high-temperature and high-pressure equipment in the American standard, and are usually used in conjunction with stainless steel bolts or alloy steel bolts
Material standard:
ASTM A193/A193M standards specify the chemical composition, mechanical properties and heat treatment requirements of gaskets to ensure their reliability and durability in high-temperature or high-pressure environments.
Application field：
ASTM A193 standard gaskets are mainly used in high-temperature, high-pressure and corrosive environments and are commonly found in the following scenarios:
Petrochemicals and energy
It is used for components such as oil refinery reactors, high-temperature pipeline flanges, and cracking furnace bolts, and can withstand temperatures above 595°C.
Electric power equipment
It is suitable for fasteners of boilers, steam turbines and nuclear power valves, which need to withstand high-temperature steam and pressure for a long time.
Offshore platforms and vessels
A193-B8M (molybdenum stainless steel) is resistant to seawater corrosion and is suitable for structural components of offshore platforms and seawater cooling systems.
Chemical equipment
Pumps, valves and sealing flanges used in acidic and alkaline media need to be matched with A194 standard nuts to ensure the self-locking performance of the threads.
Low-temperature environment
The A320-L7/L7M bolt matching washer can withstand low temperatures ranging from -46°C to -196°C, preventing brittle fracture.
