CRA Clad & Lined Pipe Manufacturer and Company Introduction

1. Jiangsu Zhongxin Pipe Sci-tec Co.,Ltd.
CRA-Clad & CRA-Lined Steel Pipe Green the World
Design by Victor
BOBPIPE Engineering (Shanghai) Co.,Ltd.

2. What is CRA-Clad & CRA-Lined Steel Pipe and Why need this?
CRA means Corrosion Resistant Alloy;
Those special pipe composited by two different
materials including inner pipe and outer pipe.
Inner CRA layer (0.25~6.0mm) normally such as
Stainless steel, Duplex, Nickel alloy, Titanium,
Hastelloy, Monel etc. which are suitable for high
corrosion environment.
Outer base material could be seamless or welded,
SAWL, SAWH, ERW, HFW, or DSAW carbon steel pipe.
Inner Lined special metal
with outer C.S Composite
The Clad & Lined Pipe (Zhongxin Brand ) can provides
the best combination of corrosion resistance of
stainless steel (including other alloy) and high
strength of carbon steel with cost effectiveness.
And just as normal C.S pipe, Zhongxin pipe can be on-
site cutting without any separation risk, together with
high once time welding pass conformity rate.
Advantage is to avoid
Corrosion with lower cost

By adopting & innovating traditional methods on bimetal pipeline, such as Hydromantic, explosion, cold
drawing, our new technology -- called “Mechanical Forward spinning pressure heat fusion technology” with
automatic production line, obtained patent for invention; (Patent#：ZL 2010 1 0517432.1、 ZL 2009 2
0233533.9、 ZL 2012 2 0645769.5）, achieved international advanced Level.
With the spinning pressure force, plasticity deformation occurs on the inner lined pipe, while elasticity
deformation on outer backing pipe; when the force disappears, the inner lined pipe is much tightly attached
to outer backing pipe. Excessive volume margin : with constraint and control. (simulated shape technology,
Conduct spiral line and spot tracing form, Compounding forming adopting continuously dynamic strain
technology)
Yielding Strength Elastic Deformation

10. 5. Why Choose Zhongxin CRA-Clad & CRA-Lined Steel ?
Original Processed
Surface of inner pipe Composite section
Fine Grain Size Improved Original Surface
Increased Hardness Good Smooth Combined
Resistance Stress Corrosion No Interspace

11. 1. Inner lined pipe with function of resistance corrosion can choose
from 0.25mm to 6mm;
2. Outer backing pipe undergoing high pressure could up to 30Mpa,
and without thickness limitation when design;
3. Zhongxin CRA-clad and CRA- lined steel Pipe could applied
temperature: -40~300℃.
4. High Bonding force between two layer material which reached to
3.0Mpa ~5.0Mpa. Bonding force is the critical factor for pipe ends
sealing welding and at site construction, cutting, welding quality,
it will avoid generating bubble and separation in lined pipe during
heat preservation and resistance corrosion.
5. Well control of the accuracy of pipe diameter around of±0.1mm which
easily guarantee of ball-passing test.
6. Once time welding pass conformity rate in site is very high base
on Zhongxin’s well sealing welding on pipes’ end before delivery.
7. Fluid will running smoothly inside, and without any blockage and
bubble phenomenon.

15. 5.4 Welding Instructions
Ø Choose welding wire according to WPS, and kept good
cleaning groove before welding;
Ø By using low current, multiple passes welding methods
while temperature well controlled.
Ø First-pass welding conformity rate exceed 95%, which
ensuring welding quality and maintaining in site service
performance of pipeline.
