A Successful Case About NACE MR0175/ISO 15156 Ateel Pipe, Flange, Pipe Fittings

Our company received an inquiry from a customer in United Arab Emirates, which includes some items required to meet the standards of NACE, they had consulted many suppliers in china but no positive feedback. The main items of the inquiry list are ANSI NACE MR 0175/ISO 15156 pipe fittings(elbows ,tees, crosses, union, reducer, bend, lap joint stub end and caps), flanges and steel pipes in NACE MR0175/ISO 15156 standard. We offered quotation for this inquiry within 24 hours, after that, the customer discuss with us about many technical problems in detail. We earned their trust and finally got to cooperation with our professional technique and top grade service.


What is ANSI NACE  MR01075?

The National Association of Corrosion Engineers proposed the document in 1975, which is now known as NACE international. There was several versions of this document until The International Standards Organization (ISO) released a similar document in 2011 (ISO 15156), and the newest version of the NACE MR0175 standard in 2002, finally the standard ANSI NACE MR0175/ISO 15156 came out.


The standard’s title is “Petroleum and Gas Industries – Materials for Use in H2S-Containing Environments in Oil & Gas Production.”In which MR0175 is the standard of material requirements for H2S containing oil and gas production and equipment. Equipment to be used in the environment with the risk of corrosion are high should meet the standard, because these conditions can lead to material failure and could pose a risk to the public, personnel, and equipment.

The ANSI NACE MR0175/ISO 15156 standards contains three parts:

1.General principles for selection of cracking-resistant materials.

2.Cracking-resistant carbon and low-alloy steels, and the use of cast irons.

3.Cracking-resistant CRAs (corrosion-resistant alloys) and other alloys.


We(Shanghai Zhucheng Pipe Fittings Manufacturing Co Ltd) is professional engaged in manufacture of Steel pipe(seamless/welded), pipe fittings(butt welding, socket weld, threaded),and flanges in pipe system of all kinds of materials(carbon steel, stainless steel,alloy steel,low temp steel,pipeline steel),including material of special standard like sulfur resistance ANSI NACE MR0175/0103. Supporting you in transporting, storage and quality testing, we commit ourselves to satisfying you with top grade product and professional service. We also support customized and reserve service with all products and cladding with special alloy steel like Inconel 625、Hastelloy C276. Our materials can be used in all kinds of technological process like SGS、ABS、BV、TUV、DNV-GL、LR、Intertek, even more, to meet your various demand, we also support processing with supplied drawings.
