Rare earth alloy wear-resistant tube

The rare earth alloy wear- esistant pipe is used for pneumatic, pump slurry, etc. Rare earth alloy wear resistant pipe has the characteristics of fast velocity and high flow rate. The conveying medium temporarily continues to produce impact on the pipe wall, wear, corrosion and so on, which causes the pipe to become tired and gradually wear out.

Rare earth alloy wear-resistant tube

Rare earth alloy wear - resistant tube is badly worn parts, such as pipe, elbow, reducer, and water intake place such as the model of integral casting, then mechanical processing method, especially the outer wear parts, especially in the elbow to the outer diameter change circle method is adopted to carry on the design, local thickening severe wear parts, but also according to various requirements, produce all kinds of irregular switch pipe fittings to meet the design requirements, straight tube is using centrifugal casting.Rare-earth wear-resistant alloy containing Cr, Ni, V, Mo, W, a variety of alloy element such as Cu, it not only has high hardness, but also has certain mechanical properties, at room temperature with good welding performance, and can be cut and the possibility of opening, also has certain corrosion resistance.

Abrasion Resistant Pipe Solutions

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

Q&A

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.

Warranty

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.

Inspections

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.
