Steel-high chromium bimetal wear-resisting compound pipe

The steel-high chromium bimetal wear-resisting compound pipe exterior wall uses the ordinary seamless steel tube, through the centrifugal forming process forms the high chromium cast steel lining compound.

The outer wall of the elbow is heated and the inner layer is made of high chromium cast steel, which has the wear-resisting property of high alloy cast steel, and can withstand pressure and has higher mechanical properties.

Features of Steel-high chromium bimetal wear-resisting compound pipe:

Good overall performance
Wear-resistant composite Pipe series is the use of bimetal composite casting process, the outer wall of the pipe using ordinary carbon steel, lined with high chromium wear-resistant alloy. Not only has the high alloy casting wear resistance, but also has the high mechanical strength and the impact resistance performance, the use is safe and reliable.

High abrasion resistance
The hard quality of high chromium cast steel is M7C3 type carbide, which has high toughness and high hardness (hv1500-1800) and thus has good wear resistance.

Strong corrosion resistance, high temperature, wear resistance
Because of the composition and structure of Ka carbide and the high content of CR, the matrix has high heat resistance and decay performance, and can show corrosion resistance in high temperature or corrosive environment. Under the condition of wet state, corrosive medium and particle scouring, the 28Cr white cast steel used in cast mode is used. In dry condition, high chromium cast steel material with martensite matrix can be obtained by heat treatment.

The compound technology is advanced and stable
High precision of mould making, wear-resistant layer thickness uniformity, and uniform, stable performance, especially for straight tubes and special-shaped tubes for the overall composite (elbow, tee, four-pass, tapered pipe, variable diameter pipe, non-thick wall pipe, eccentric tube can do the whole compound).

Good thermal shock resistance
As the main product of the internal and external thermal expansion coefficient is similar to the temperature of the rapid changes and often changing conditions, will not occur due to the loss of the inner layer of failure.


It can be installed by flange, quick connector and direct welding. Because of the high impact resistance of the composite pipe, it is convenient to cut, unload, weld, install and overhaul in the pipeline system when local pipe plugging occurs.

Layer construction:


  • Packed in wooden crates, wrapped in plastic, and suitably protected for sea-worthly delivery or as requested.
  • Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles.

We have a team of experienced professionals with years of experience in manufacturing.

Abrasion Resistant Pipe Solutions

Conveying highly abrasive materials, steel piping systems are under constant attack often over long distances.


Because the outer surface behaves like mild steel, the product can be cut and welded with proper procedure in the field, configured into a variety of fittings, and can accept the standard end options of flanges, weld rings and couplings.


We are Quality Department tests and ensures all of our products are 100% inspected unreported. To an offer we customers additional corps of mind, all our products carry a 24-month warranty against defects or faulty workmanship.We fluid-flow products such as pipe and fittings, chokes, orifice plates, etc, carry a warranty against, erosion, defects, and/or faulty workmanship.

The warranty is determined to each creator and the maximum duration maximally in service. Should any of the RS fail within the warranty period, We'll replace or repair the defective product (s) at No. end user. Please contact the Sunny steel for details on the How to obtain a warranty for our products.


As part of our quality regimen, 100% of incoming raw materials, semi-finished products, as well as finished products are thoroughly inspected prior to being entered into our inventory. We have established multiple hold points throughout fabrication as well as a comprehensive final inspection for all products.
