Stainless steel pipe is a hollow strip of round steel, which is
widely used in petroleum, chemical, medical, food, light industry,
mechanical instrumentation and other industrial pipelines and
mechanical structural components. In addition, when the bending and
torsional strength are the same, the weight is light, so it is also
widely used in the manufacture of mechanical parts and engineering
structures. Also used as furniture and kitchenware.Use high quality carbon structural steel hot rolled or cold rolled
(dial) seamless steel tubes. Mainly made of 10, 20 steel, in
addition to ensure chemical composition and mechanical properties
to do water pressure test, crimping, flaring, flattening and other
tests. Hot rolling in hot rolling state delivery, cold rolling
(dial) in heat treatment state delivery. High pressure boiler
seamless steel tube: Mainly used in the manufacture of high
pressure and over pressure steam boiler pipes, etc. With high
quality carbon structural steel, alloy steel and stainless Heat
resistant steel seamless steel tube, these often under high
temperature and high pressure boiler tube, tube in high temperature
flue gas and steam will happen under the action of oxidation and
corrosion, so the steel pipe with high rupture strength, high
oxidation resistance, And has good organizational stability, using
steel: high quality carbon structural steel steel 20G, 20MnG,
25MnG; Alloy structure steel 15MoG, 20MoG, 12CrMoG, 15CrMoG,
12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.; Rust heat resistant steel
commonly used 1Cr18Ni9, 1Cr18Ni11Nb high pressure boiler pipe in
addition to ensure the chemical composition and mechanical
properties, to do water pressure test, to make flaring, flat test.
Steel tubes are delivered in heat treatment condition. In addition,
the microstructure, grain size and decarburization layer of
finished steel tubes are also required. Geological drilling and oil
drilling seamless steel pipe: in order to explore the underground
rock structure, groundwater, oil, natural gas and mineral
resources, the use of drilling Wells. Oil and natural gas
exploitation is inseparable from drilling, geological drilling with
oil drilling with seamless steel pipe is the main drilling
equipment, mainly including core outer pipe, core inner pipe,
casing, drill pipe, etc.. Due to the drilling pipe to work deep
into thousands of meters of stratum depth, the working conditions
are extremely complex, drill pipe under tensile, compression,
bending, torsion and unbalanced impact load and other stresses, but
also by mud, rock wear, therefore, the requirements of the pipe
must have enough strength, hardness, wear resistance and impact
toughness
Precise custom outer diameter and inner diameter
--Tight tolerances, resulting in reduced machine time / Dimensional
accuracy
--Smooth and Clean OD and ID surfaces
--Excellent machining characteristics
--Wider range of physical properties attainable through process and
annealing options
