Press releases
this long-standing partnership: “With over
30 years of operational experience, Jiuli is
committed to producing tubes that provide
50, 60, or even 100 years of safe service
for our customers. The high deformation
capacity and precision of SMS group’s cold
pilger mills ensure the performance and
lifespan of these materials. Although the
equipment is cost-intensive, the considera-
tion of the total lifecycle cost is reasonable.
Consequently, this investment decision is
based on the above strategic considera-
tions. By continuing to choose SMS group’s
equipment, we aim to enhance our capa-
bility to deliver high-performance, ultra-re-
liable materials for Jiuli’s global high-end
customers.”
broader strategic expansion plan, which
aims to increase production capacity and
enhance the quality of the seamless stain-
less steel and special alloy tubes produced.
The KPW 50 LC mill stands out for its ability
to process hollows with initial diameters
ranging from 64 millimeters to 25 millim-
eters. It efficiently reduces these to final
diameters between 48 millimeters and 14
millimeters, utilizing a maximum rolling
force of 1,000 kilonewton and operating
at a stroke rate of 200 strokes per minute.
This precision engineering ensures that the
tubes produced meet the required stand-
ards of wall thickness and diameter, result-
ing in products with superior mechanical
properties and optimized microstructural
characteristics.
The two new KPW 25 LC mills are specifi-
cally engineered to handle smaller tube di-
ameters, processing hollows measuring be-
tween 38 millimeters to 12 millimeters and
achieving final dimensions ranging from 30
millimeters to 8 millimeters. Designed for
high-speed production, they operate at a
stroke rate of 320 strokes per minute and a
maximum rolling force of 440 kilonewton.
Advanced control of the feed movement
ensures uniform wall thickness distribution
and exceptional surface quality, which are
critical for applications requiring high preci-
sion and reliability.
Beyond the mechanical capabilities of
these mills, the comprehensive scope of
supply from SMS includes the integrated
electrical and automation systems, fluid
systems and all required tools and spare
parts. SMS will also provide extensive tech-
nical support during the installation, com-
missioning and testing phases, ensuring
the seamless integration of these advanced
technologies into Jiuli’s existing production
framework.
Jiuli’s partnership with SMS dates back to
2010, when Jiuli successfully integrated
several cold pilger mills from SMS across
various capacity levels. This long-standing
relationship underscores Jiuli’s confidence
in SMS’ technological expertise and ser-
vice excellence. Li Zhengzhou, President
of Zhejiang Jiuli Hi-Tech Metals Co., values
