Aviation pipe is the general term and abbreviation for seamless steel pipes used in the manufacturing of aircraft and other aviation and aerospace equipment. Aviation pipe includes high-pressure conduits, fuel pipes, speed measuring pipes, rivet pipes, gas plate pipes, and landing pipes. As aviation pipe is a key material used in aviation, its quality, reliability of service life, accuracy and strength of dimensions (materials that are no longer processed), and stability of weight are all very important, and its requirements are very strict. Therefore, aviation pipe is widely recognized as one of the seamless steel pipes with the strictest and highest technical requirements, and its development level represents the level of seamless steel pipe production in a country.
Seamless steel pipes for aerospace equipment
The varieties of aviation management are divided into two categories:standard varieties and non-standard varieties.
The standard varieties include aircraft stainless seamless steel pipes (YB678-1971); 18A hollow rivet thin-walled seamless steel pipe for aircraft (YB679-1971); Thin walled seamless steel pipe for aircraft structural steel (GJB2609-1996); 20A thin-walled seamless steel pipe for aircraft ducts (YB681-1971); Aircraft structural steel thick walled seamless steel pipe (GJB2608-1996); Aerospace high-temperature alloy cold drawn (rolled) seamless steel pipe (YB1206-1980).
Thick walled seamless steel pipes for aircraft structural steel
Non standard varieties include steel pipes for cold air and oxygen cylinders used in the aerospace industry (Song'an 19661), (Ante 12-1969), and (Anshangrong 1969-1); Cold drawn (rolled) seamless steel tube for manufacturing airspeed tubes in the aerospace industry (Loose Saddle 2-1967); Cr17Ni2 cold drawn seamless steel pipe for manufacturing flat nozzles in the aviation industry (loose saddle 3-1967); 30CrNi2VA Tail Shaft Tube Trial Production Agreement (Tail Test-701); GR-2 and 3N602 high-temperature alloy hot-rolled seamless steel pipes (Anshe 420-1965); High temperature alloy seamless steel pipe.
