Tailored engineering support and fast-track shipping logistics designed specifically for Iraq’s major industrial basins and ongoing energy infrastructure rehabilitation.
Upstream oil extraction in Southern Iraq requires pipe fittings capable of withstanding high concentrations of Hydrogen Sulfide (H2S) and Carbon Dioxide (CO2). Our seamless carbon steel fittings in ASTM A234 WPB and alloy steel fittings meeting NACE MR0175 / ISO 15156 standards prevent Hydrogen-Induced Cracking (HIC) and Stress Corrosion Cracking (SCC) in high-pressure oil gathering lines and gas-oil separation plants (GOSP).
Downstream petroleum refining facilities demand high-temperature seamless elbows, equal tees, and weld neck flanges. Viha Steel & Forging supplies certified alloy steel fittings (ASTM A234 WP11/WP22) and stainless steel 316L lap joint assemblies that maintain dimensional integrity under continuous thermal cycling and high-pressure catalytic cracking processes.
Long-distance overland pipelines connecting northern fields (Kirkuk) to strategic export routes require uniform wall thickness and high yield strength seamless fittings up to 24 inches NB. Our seamless long-radius 90-degree elbows reduce hydraulic friction losses and accommodate pigging operations across desert terrains with extreme diurnal temperature shifts (0°C to 55°C).
Marine environments along the Arabian Gulf present severe pitting corrosion challenges. For seawater intake pipelines and desalination plant cooling systems in Al-Faw, we engineer Duplex UNS S32205 flanges and SS316L seamless fittings with elevated Pitting Resistance Equivalent Numbers (PREN ≥ 34) to resist localized chloride attack.
Understanding the shifting regulatory landscape, quality benchmarks, and logistics requirements for industrial piping materials imported into the Iraqi market.
With Iraqi oilfields extracting increasingly sour crude reserves, major international oil companies (IOCs) and state companies (such as Basra Oil Company - BOC, and North Oil Company - NOC) strictly enforce NACE MR0175 compliance. Fittings must undergo rigorous hardness testing (maximum 22 HRC) and wet H2S cracking evaluations prior to installation.
Unverified gray-market piping materials present catastrophic failure risks. Procurement policies in Iraq now universally demand 100% heat-traceable Mill Test Certificates certified to EN 10204 3.1. Chemical compositions, Charpy V-notch impact values, and hydrostatic test pressures must match physical heat numbers stamped directly on each fitting.
Efficient supply chains into Iraq depend on standardized ocean freight packing and clear customs documentation. Materials exported from our facilities are shipped in sea-worthy, heat-treated ISPM 15 wooden crates with heavy-duty plastic cap end protectors, VCI anti-rust film, and full shipping mark documentation optimized for smooth clearance through Umm Qasr Port.
Combining decade-long manufacturing expertise in Mumbai with global export standards to deliver unmatched piping reliability.
Viha Steel & Forging (established in 2010) is a certified manufacturer approved under Pressure Equipment Directive (PED 2014/68/EU) and an active member of the Fastener Manufacturers Association of India (FMAI). Our integrated forging facility operates under strict ISO 9001:2015 quality management procedures.
Every batch of seamless fittings, forged flanges, and high-tensile studs undergoes stringent QA protocols: Positive Material Identification (PMI via XRF spectrum analysis), Radiographic Testing (RT) on welded connections, Ultrasonic Testing (UT) for internal flaw detection, and Magnetic Particle Inspection (MPI) to guarantee zero surface micro-cracks.
Direct answers to common technical, compliance, and logistics questions encountered when importing seamless pipe fittings and flange assemblies into Iraq.
We manufacture and export seamless butt weld fittings across the entire dimensional spectrum, including Schedule 20, Schedule 40 (STD), Schedule 80 (XS), Schedule 120, Schedule 160, and XXS (Double Extra Strong) in accordance with ASME B16.9. Custom heavy wall thickness fittings for ultra-high-pressure injection lines are also forged to order.
Yes. We specifically supply carbon steel (ASTM A234 WPB / A105N) and stainless/duplex steel components manufactured to meet NACE MR0175 / ISO 15156 guidelines. Material heat treatments are controlled to ensure hardness levels remain below 22 HRC, preventing sulfide stress cracking in high H2S oilfield environments such as Rumaila and West Qurna.
Every shipment is accompanied by a full EN 10204 3.1 Mill Test Certificate detailing ladle chemical analysis, mechanical property testing (Tensile, Yield, Elongation), Charpy V-Notch impact testing (especially for A420 WPL6 low-temp fittings), heat treatment records, NDT inspection logs, and hydrostatic pressure test verifications.
Sea freight shipments are routinely routed to Umm Qasr Port in Basra Governorate, serving southern projects directly. For northern destinations such as Erbil or Sulaymaniyah, land transit routes via Mersin Port (Turkey) or Jordan border terminals can be arranged depending on client customs preferences and project timelines.
Absolute integrity upon arrival is vital. All carbon steel and alloy pipe fittings are thoroughly cleaned, dried, and coated with black rust-preventative varnish, transparent anti-corrosion lacquer, or heavy rust-inhibiting oil. Pipe ends are fitted with protective plastic bevel caps to prevent physical edge damage during transit.
Yes. In addition to standard ASME B16.9 and B16.5 components, our machine shop custom forges heavy ring flanges, orifice flanges, long weld necks, and customized reducing tees to exact customer-supplied engineering drawings, complete with custom bevel angles and specialized face finishes (smooth or serrated finish).
