Jiangsu Zhongxin Pipe Sci-tec Co.,Ltd.CRA-Clad & CRA-Lined Steel Pipe Green the World

Design by Victor

BOBPIPE Engineering (Shanghai) Co.,Ltd.

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 (0.3~5.0mm) 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

4.1 Technical Characteristics and Applicability

Backing Steel

Inner Steel

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

5. Why Choose Zhongxin CRA-Clad & CRA-Lined Steel ?

Original ProcessedSurface of inner pipe Composite section

Fine Grain Size Improved Original SurfaceIncreased Hardness Good Smooth CombinedResistance Stress Corrosion No Interspace

1. Inner lined pipe with function of resistance corrosion can choose from 0.2mm to 5mm;

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.

5.4 Welding Instructions

Choose welding wire according to WPS, and kept good

cleaning groove before welding;

By using low current, multiple passes welding methods

while temperature well controlled.

First-pass welding conformity rate exceed 95%, which

ensuring welding quality and maintaining in site service

performance of pipeline.

Our CRA-Clad & CRA-Lined Steel

Pipe will strictly base on following

International and China Standards.
