High chromium cast iron pipes

High chromium cast iron pipe is an alloy steel intended for high temperature and high pressure services.

High chromium cast iron pipes
Features of High chromium cast iron pipes:

The late eighty`s, American technology of rare eath wear resistant steel was introduced into our country. The relevant experts researched and made many experiments. The rare-earth wear-resistant steel had occupied the main position.Rare-earth wear-resistant steel is based on 40 steel. Cr, Ni, Si, Mo, Mn, Re elements are mixed in 40 steel forming low alloy steel which carbon content is 0.35~ 0.45%.

Chrome-Moly
  • Chromium-Molybdenum Alloy Steel or Chrome-Moly, CrMo is an alloy steel intended for high temperature and high pressure services.
  • Chrome-Moly is used in the power generation industry and the petro-chemical industry because of its tensile strength, corrosion resistance and high-temperature strength.
  • Chrome-Moly has a better strength to Weight ratio than steel, which enables designers to use thinner wall pipe or smaller diameter tubing to reduce overall weight.
  • Chromium-Molybdenum Alloy Steel has strong resistance to rupturing at high temperatures and high pressures.
  • Chrome-Moly is also resistant to cracking from hydrogen attack and hot sulfide corrosion cracking.
  • Chrome-Moly grades P-11, P-22, P-91 and P-92 are used in the power industry.
  • Chrome-Moly grades P-5 and P-9 are used in petro-chemical refinery processes.
  • Chrome-Moly Forged Fittings & Flanges are available in grades F-5, F-9, F-11, F-22, F-91, F92.
  • Chrome-Moly Alloy Butt Weld Fittings are available in grades WP-5, WP-9, WP-11, WP-22, SP-91, WP-92.
  • F11 and F22 meet NACE-MRO 175.

Performance indicators:

  • Grade: ZG40CrNiMoMnSiRe
  • Hardness: HRC ≥ 40
  • Impact toughness: ≥ 14J/cm2
  • Tensile strength: ≥ 700MPa

Uses:

Rare high-strength low-alloy heat-resistant, wear-resistant steel parts for the power plant boiler systems in coal, powder, ash slagging pipeline.

Packing:

  • 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.

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.
