Product DescriptionZhengde Automobile exhaust pipes include
straight pipes, perforated pipes, large pipes, bent pipes, spinning
parts, stamping parts, welded assembly, etc. The main types of
welded steel pipes for automobiles include automobile transmission
shaft pipes, automobile muffler pipes, automobile condenser pipes,
automobile exhaust pipes, automobile control shaft pipes,
automobile thrust pipes, automobile shock absorber oil storage
pipes, etc. Seamless steel pipe for automobile axle casing
(GB3088-82) is a high-quality carbon structural steel and alloy
structural steel hot-rolled seamless steel pipe used in
manufacturing automobile axle casings and drive axle housing axle
tubes. Stainless steel welded pipes are most commonly used in the
automobile industry in exhaust systems, accounting for more than
1/2 of the total stainless steel consumption in automobiles, and
80% are ferritic stainless steel. The exhaust gas generated by the
car engine passes through the exhaust air intake pipe, front pipe,
hose, converter, center pipe and finally flows out of the muffler.
Generally, 409L, 439M, and 436L materials are used to produce
exhaust pipes. They are characterized by good corrosion resistance
under high temperature and good strength under high temperature
conditions. They are also clean and environmentally friendly. They
are the most commonly used exhaust pipe materials in the automotive
industry. , has been recognized in the industry. According to
estimates, the stainless steel pipes used in automobiles account
for about 1.5% of the total consumption of stainless steel pipes by
downstream users, and the usage ratio of stainless steel seamless
pipes and welded pipes is about 2:1. Each car uses stainless steel
welded pipes between 24 and 30kg, which are mainly used in three-no
purifiers and exhaust pipes. Stainless steel used in exhaust
systems in the automobile manufacturing industry is T409, T439,
AL409, 436S, etc. As the service conditions of the exhaust system
become more severe and the exhaust temperature rises to
950°C~1000°C, the stainless steel used for the exhaust manifold has
progressed from SUH409L (low grade) and SUS430JIL (high grade) to
the high-performance material SUS444. The temperature of the
muffler system can reach 300°C, and the materials used have similar
changes. Due to increasingly fierce market competition, low-cost
materials have become a new development direction.Our
