Stainless Steel Pipes Introduction
First, the thicker the wall thickness of the product, the more
economical and practical it is, and the thinner the wall thickness,
the higher the processing cost; secondly, the technology of the
product determines its limited performance, generally The precision
of seamless steel pipe is low: uneven wall thickness, low
brightness inside and outside the pipe, high cost of sizing, and
there are pits and black spots on the inside and outside that are
not easy to remove; third, its detection and shaping must be
processed offline. Therefore, it reflects its superiority in terms
of high pressure, high strength, and mechanical structural
materials.

Stainless steel seamless pipe is a steel pipe that is resistant to
weak corrosive media such as air, steam, and water, and chemically
corrosive media such as acid, alkali, and salt. Also known as
stainless acid-resistant steel pipe.
The corrosion resistance of stainless steel seamless pipes depends
on the alloying elements contained in the steel. Chromium is the
basic element for stainless steel to obtain corrosion resistance.
When the chromium content in steel reaches about 12%, chromium and
oxygen in the corrosive medium act to form a thin oxide film
(self-passivation film) on the steel surface. , which can prevent
further corrosion of the steel matrix. In addition to chromium, the
commonly used alloying elements for stainless steel seamless pipes
are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc.,
to meet the requirements of various uses for the structure and
properties of stainless steel.
Stainless steel seamless pipe is a kind of hollow long round steel,
which is widely used in petroleum, chemical, medical, food, light
industry, mechanical instrumentation and other industrial
transportation pipelines and mechanical structural components. In
addition, when the bending and torsional strength are the same, the
weight is lighter, so it is also widely used in the manufacture of
mechanical parts and engineering structures. It is also commonly
used to produce various conventional weapons, barrels, shells, etc.
