Cold Drawn seamless steel pipe DIN ST52 Mild Carbon Steel Seamless
Pipes
Product Description
The advantages of seamless steel pipes are high pressure
resistance, good toughness, long pipe sections and few joints. The disadvantage is that it is expensive, easy to corrode, and thus
has a short service life.
(1) Ordinary seamless steel pipe
Ordinary seamless steel pipes are rolled from ordinary carbon
steel, high-quality carbon steel, low-alloy steel or alloy
structural steel. Variety of specifications, high strength,
It is the most commonly used pipe material for pipelines and is
widely used in pipelines with a working pressure below 1.6MPa. Such as heat pipelines, refrigeration pipelines, compressed air
pipelines, oxygen pipelines, acetylene pipelines, and various
chemical pipelines except for strong corrosive media.
carbon seamless steel pipe
(2) Stainless steel seamless steel pipe
Stainless steel seamless pipe is made of chromium-nickel stainless
steel, and there are two kinds of hot-rolled and cold-rolled
(cold-drawn) pipes. It is characterized by strong acid resistance and corrosion
resistance, but it is expensive and is mainly used for chemical
pipelines with special requirements.
(3) Welded steel pipes for low-pressure fluid transportation
Welded steel pipes for low-pressure fluid transportation are seamed
pipes, generally made of Q215-A, Q235-A, Q255-A ordinary carbon
steel. According to the surface quality, it is divided into two types:
galvanized (white iron pipe) and stainless steel (black iron pipe); according to whether the pipe end is threaded or not, it can be
divided into two types: threaded and unthreaded; according to the thickness of the pipe wall, there are ordinary and
thickened two kinds.
Ordinary steel pipes can generally withstand 2.0MPa hydraulic test,
and thickened pipes can withstand 3.0MPaz hydraulic test. Ordinary steel pipes and thickened pipes can generally be used for
Pipes with lower medium temperature for working pressure gauges. For example: Nominal diameter not more than 100mm can be used for
indoor heating pipes, steam pipes and hot water pipes with a
working pressure not exceeding 1.0MPa and medium temperature not
exceeding 200°C; nominal diameter not greater than 65mm, used for working pressure
not exceeding 0.8MPa Compressed air pipelines; nominal diameter not greater than 50mm can be used for gas or
natural gas and clean water pipelines.
Galvanized steel pipe in hot water above 60°C and when the
temperature is 60~120°C, zinc reverses the polarity. In fact, it does not prevent the corrosion of steel, but promotes
the corrosion of steel, which quickly makes the water pipe rust and
eventually lead to perforation.
