Lined stainless steel meets GB12771—2008 and CJ/T151-2001 requirements
Fully meet
Health performance
The product health performance should meet GB/T17219-1998 requirements
Detection fully meet
Hydraulic test
The product hydraulic test should meet GB/T241-2007 requirements
Detection fully meet
Flattening test
Diameter is greater than 50mm. Weld cracks will not occur after flattening.
Detection fully meet
Combination strength
Combination strength should be no less than 0..2MPa
Combination strength 0.5-3MPa is better than the standard

 
Composite technology is also the most reliable composite technology present. The combination strength is the main parameters to measure the composite quality of lined stainless steel, and is also the main factors to avoid galvanic corrosion. Our products use positive spinning mosaic patent.
 
 
 
Huayang brand composite pipe lined with stainless steel, which uses GB hot dip galvanized steel pipe, welded pipe, spiral pipe, seamless steel tubes for the outer layer and imported or domestically produced high-quality stainless steel pipe for the inner. It is compound by special process. Because it has advantages of both outer and inner layers of the pipe, simultaneously overcome their respective shortcomings, it has good technical characteristics and prospects, in recent years it has been gradually chosen by building design institutes and engineering. Its main technical features are as following:
 
I.With good mechanical properties
 
Because its outer and inner layers are metallic materials, so it has strong compressive resistance and impact resistance, tensile strength, high elongation, high elastic modulus and small thermal expansion coefficient. It’s especially suitable for hidden announced of standpipe of building water supply.
 
II. High combination strength
 
Carbon steel composite pipe lined with stainless steel sets the inner stainless steel tube into the hot dip galvanized steel pipe. By the role of mechanical force, it makes elastic deformation of the outer carbon steel pipe and plastic deformation of the inner stainless steel tube. Two layers of material closely mosaic, its bonding strength exceeds the national standards for more than 1MPa. Because the inner and outer layer material is similar, so it will not occur splitting.
 
III. Good anti-rust and corrosion resistance
 
Since stainless steel has chemical properties of rust-proof, resistant to oxidation, resistant to acid and alkali, good corrosion resistance among crystals, its rust-proof and anti-corrosion are more superior to other materials. Connection of composite pipe lined with stainless steel and pipe lined with stainless steel and stainless steel tube supporting pieces. Its application scope is broader, in addition to water and heat supply, it also applies to the chemical, pharmaceutical, petroleum, food, electricity and other industries with high corrosion requirements.


IV.              Heat and cold resistant , be used both hot and cold 

Liquid nitrogen freezers are made of stainless steel, so stainless steel composite pipe has superior heat and cold resistance. Regardless of cold water pipe and hot water pipes, one pipe with two usages. Hot and cold both are ok.
 
V.                 Big diameter, weak resistance
 
Stainless steel of inner layer of composite pipe lined with stainless steel is only 3B8mm, so the actual diameter and regulated diameter are basically consistent. Inner-wall is smooth, no scaling, the resistance is small, and large amount of water.
 
VI.              High working pressure
 
Composite pipe lined with stainless steel can ensure that the working pressure is greater than 2.5MPa and can meet all types of building water supply project needs.
 
VII.           Easy to install and technology is simple.
 
Carbon steel composite pipe lined with stainless steel can be installed as common galvanized steel pipe. Use wire connection below DN100 and groove connection above DN 100. Its technology is simple and installation workers don’t need specialized training.
 
VIII.         Health and environmental, with good security.
 
Because chemical properties of stainless steel is stable and is no damage to the human body, international and domestic medical profession use stainless steel as materials of a variety of stents, plywood, inner screws implanted in the human body. Composite pipe lined with stainless steel and composite pipe supporting fittings connect, coupled with the non-toxic anti-rust treatment of connector thread and the ending surface can effectively prevent the secondary pollution of water quality. Composite pipe lined with stainless steel parts which can systematically remove the transmission fluid are all stainless steel material. It’s health and environmental, with good safety and are in line with "ecological house" requirements and ideas of the people-oriented. It can be widely used in following areas:
 
    Water supply pipe
 
     Outdoor water supply aqueducts
 
      Pump house pipe
 
    High-rise buildings water supply pipe, water distribution trunk pipe
 
    Air conditioning circulating water pipes, fire sprinkler pipe
 
    Hot water pipes, straight drinking water pipes
 
    Water pipes of fine decoration upscale real estate
 
     Hot water pipes of the solar industry
