Product Description
Carbon seamless steel pipe is a kind of strip steel. Steel pipe
with hollow cross-section, a large number of pipes used to
transport fluid, such as the transportation of oil, natural gas,
gas, water and some solid materials such as pipes. Steel and round
steel and other solid steel compared to the same bending strength
in the same bending, lighter weight, is an economic section of
steel, is widely used in the manufacture of structural parts and
mechanical parts, such as oil drill pipe, Bicycle frames and steel
construction scaffolding. The use of carbon seamless steel pipe
manufacturing ring parts can improve material utilization, simplify
the manufacturing process, save materials and processing time, such
as rolling bearing rings, jackets, etc., has been widely used to
manufacture steel pipe.
Seamless steel pipe is manufactured from solid, round steel billets
that are pierced through the center with a mandrel. The billet is
rolled and stretched through a hollow billet until it reaches a
customer's specification. Because of its uniform shape and ability
to withstand pressure and heat, seamless steel pipe is an ideal
material for many industries.
ZhengDe Metal provides a variety of seamless pipe to meet your
application needs, offering a large selection of sizes and lengths.

Our Advantages

Three-roll pipe mill
The seamless steel pipe produced by the three-roll mill for
hot-rolling seamless steel pipe has high precision. Because of the
cross-rolling with the mandrel, the rolling action is repeated many
times in one pass, which greatly improves the accuracy of the wall
thickness and is not easy to produce. Defects such as scratches,
ears, and green lines; the flexibility in production is large, and
the pass size can be changed with the help of the clutch of the
roll.
Adequate inventory
Standing inventory of carbon seamless tubes, seamless
special-shaped tubes, alloy seamless tubes, precision tubes.
Various types of seamless steel pipes with a specification of
5-426*0.5-60mm and a length of 2-16m. The cold-rolled precision
bright tubes produced by our factory have smooth appearance,
uniform wall thickness, no oxide layer, and high precision. The
inner hole of the steel pipe can be divided into round type, spline
type, plum blossom type, etc. It is widely used in automobiles,
motorcycles, electric power, petrochemicals, ships, aerospace,
bearings, pneumatic components, oil cylinders, boiler equipment,
medical equipment, fitness equipment and other industries.
Attention to detail
No matter how to choose the hot-rolled seamless steel pipe, its
quality cannot be ignored. It must be noted that there should be no
defects on the surface, such as small cracks or scars, etc., and
that the thickness of the pipe wall is the same to ensure
uniformity. The physical comparison is still very important. Only
after the basic comparison of the physical objects is done, can the
steel pipes that meet the needs be selected. The processing
technology of each seamless steel pipe is different, which will
also affect its application field. Now it is generally processed by
cold drawing and hot rolling, and the processing effect of the two
and the application of steel pipes will also have certain
differences.
Applicable scene
Hot-rolled seamless pipes specifically include low and medium
pressure boiler steel pipes, high-pressure boiler steel pipes,
seamless steel pipes for ships, petroleum cracking steel pipes,
seamless steel pipes for high-pressure fertilizer equipment, oil
jacket steel pipes, pipeline steel pipes, hollow sucker rods, and
ordinary fluid steel pipes. , structural seamless steel pipes and
imported alloy steel pipes, etc., with rich varieties and complete
specifications, widely used in petroleum, chemical, electric power,
boilers, ships, machinery and other industries, and have been sold
all over the world.
