Galvanized Pipe DN50 Galvanized Steel Pipe DN100 Galvanized Large
Diameter Pipe DN300-DN600 Seamless Steel Pipe
The material classification
Steel pipe can be divided into carbon pipe, alloy pipe, stainless
steel pipe and so on.
Carbon pipe can be divided into ordinary carbon steel pipe and high
quality carbon structure pipe.
Alloy tube can be divided into: low alloy tube, alloy structure
tube, high alloy tube, high strength tube. Bearing tube, heat and
acid resistant stainless tube, precision alloy (such as cutting
alloy) tube and high temperature alloy tube, etc.
Connection type classification
Steel pipe can be divided into light pipe (pipe end without thread)
and wire pipe (pipe end with thread) according to the connection
mode of pipe end.
Wire tube is divided into: ordinary wire tube and tube end
thickened wire tube.
Thickening wire pipe can also be divided into: outer thickening
(with external thread), inner thickening (with internal thread) and
inner and outer thickening (with internal and external thread) and
other ground wire pipe.
If the thread type can also be divided into: ordinary cylindrical
or conical thread and special thread and other ground thread tube.
In addition, according to the needs of users, wire pipes are
generally equipped with pipe joints delivery.
Classification of plating characteristics
According to the surface coating characteristics of steel tube can
be divided into: black tube (not coated) and coated tube.
Galvanized pipe, aluminum pipe, chromium pipe, aluminized pipe and
other alloy layer of steel pipe.
Coating pipe has outer coating pipe, inner coating pipe, inner and
outer coating pipe. Commonly used coatings are plastic, epoxy
resin, coal tar epoxy resin and a variety of glass anti-corrosion
coating materials.
Galvanized pipe is divided into: KBG pipe, JDG pipe, threaded pipe
and so on.

4. Petroleum geology drilling pipe. Such as: oil drilling pipe, oil
drill pipe (kelly and hexagonal drill pipe), drilling, oil pipe,
oil casing and all kinds of pipe joint, geological drilling pipe
(core pipe, casing, active drill pipe, drilling, hoop and pin
joint, etc.).
5. Tubes for chemical industry. Such as: petroleum cracking pipe,
chemical equipment heat exchanger and pipe with pipe, rust acid
resistant pipe, chemical fertilizer with high pressure pipe and
transport chemical medium with pipe.
6. For other departments. Such as: container tube (high pressure
gas cylinder tube and general container tube), instrument
instrument tube, hand case tube, injection needle and medical
instrument tube.
