View Details & InquiryNavigating extreme thermal stress, corrosive H2S environments, and rapid infrastructure expansion
Iraq's industrial sector is undergoing a massive transformation driven by extensive upstream oil field developments in the southern oil basins (such as Rumaila, West Qurna, Majnoon, and Halfaya), modernization of key refineries in Baiji, Basra, and Karbala, alongside sweeping reconstruction projects in municipal water treatment and electrical grid expansion nationwide.
In these aggressive operational conditions, pressure gauges serve as critical first-line diagnostic instruments. Operating in Iraq requires pressure measuring systems that can endure ambient summer temperatures exceeding 55°C (131°F), high particulate atmospheric sandstorms (fine silica dust), and severe internal process vibration caused by heavy-duty positive displacement pumps and gas compressors.
Standard brass or partial-alloy pressure gauges frequently suffer from rapid degradation, internal movement wear, pointer flutter, and Bourdon tube oxidation when deployed in sour gas (H2S enriched) environments or coastal marine air around the Umm Qasr port terminal. Consequently, EPC contractors and procurement managers across Iraq are increasingly standardizing on All-Stainless Steel (SS 304 / SS 316L) Pressure Gauges to achieve operational safety, zero-leak integrity, and long-term TCO (Total Cost of Ownership) reduction.
Engineered for extreme longevity under high thermal expansion, pulsation, and chemical attack
For applications involving sour crude, natural gas processing, or active chemicals, Bourdon tubes and socket connections engineered from AISI 316L (low carbon stainless steel) prevent stress corrosion cracking (SCC) and pitting caused by hydrogen sulfide (H2S) and chlorides, conforming strictly to NACE MR0175/ISO 15156 standards.
To eliminate pointer oscillation under severe mechanical vibration (such as near turbine exhausts or hydraulic power units), gauges are filled with 99.5% pure industrial Glycerin or high-temperature Silicone Fluid (-40°C to +200°C). Liquid filling lubricates internal movements and cushions internal gears from sudden pressure spikes.
Safety is non-negotiable in downstream refineries. Our heavy-duty stainless steel pressure gauges feature a solid front baffle wall and a rear blow-out disc compliant with EN 837-1 / ASME B40.100 S3 safety standards, ensuring process media is safely directed backward in the event of an accidental overpressure rupture.

Tailored pressure measurement solutions engineered for specific Iraqi operational field conditions
In high-pressure wellhead manifolds and degassing stations (DS) across southern Iraq, all-SS pressure gauges equipped with high-pressure diaphragm seals monitor crude oil suction and discharge lines. Their rugged SS316L housing resists corrosive ambient coastal humidity and sulfur dioxide exposure.
Gas-insulated switchgear (GIS) substations managed by the Iraqi Ministry of Electricity require hermetically sealed 2.5-inch SF6 gas density monitors with temperature compensation. These instruments prevent dangerous electrical arcing by continually validating SF6 gas pressure across extreme seasonal temp fluctuations.
Municipal water treatment plants in Baghdad and Mosul utilize sanitary stainless steel differential pressure transmitters and bimetal thermometers to control reverse osmosis (RO) membrane filter pressure and monitor chemical dosing pump output without fluid contamination.
Providing Iraqi industrial distributors and contractors direct access to OEM manufacturing efficiency
By sourcing directly from advanced Chinese manufacturing hubs like Huzhou Accuracy Instrument Co., Ltd., Iraqi engineering firms reduce procurement expenditures by 40% to 60% compared to European trading intermediaries—while receiving instruments fully certified to ISO 9001:2015, CE, and EN 837-1 standard accuracy.
We maintain streamlined shipping corridors connecting major Ningbo and Shanghai ports directly to Umm Qasr Port (Basra) and inland container depots in Erbil and Baghdad. Our dedicated export department handles all Iraqi customs clearance documentation, including COSQC compliance certificate issuance.
Huzhou Accuracy Instrument CO LTD is professionally engaged in the development, sales and service of industrial mechanical pressure gauges, bi-metal thermometers, SF6 manometer, pressure sensor. Products are widely used in various applications such as Mechanical Engineering, Chemical Engineering, Food Industry, Pharmaceutical, and high technology electric appliances.
Established over two decades ago, our pressure gauge manufacturing facility spans 3,000 square meters, equipped with advanced production lines and rigorous quality control systems. As an industry leader, we integrate innovation with precision engineering to deliver reliable measurement solutions for global clients.
Ensuring 100% frictionless import compliance for contractors and government procurement bodies
Importing mechanical pressure gauges into Iraq requires strict adherence to the **Central Organization for Standardization and Quality Control (COSQC)** regulations. Products entering ports such as Umm Qasr or Erbil International Airport must be accompanied by a Verification of Conformity (VoC) certificate issued by accredited international inspection bodies (e.g., SGS, TÜV Rheinland, or Intertek).
Our manufacturing workflow incorporates comprehensive batch inspection protocols that directly align with Iraqi regulatory demands:

Iraqi crude oil and associated natural gases contain significant concentrations of hydrogen sulfide (H2S) and ambient airborne salinity, particularly in Basra and southern oilfields. Brass components corrode rapidly and embrittle under H2S exposure. Stainless steel (304 or 316L) offers superior chemical immunity, higher pressure burst safety, and extended operational longevity.
Standard liquid filling can leak or cause dial discoloration under extreme thermal expansion. We utilize temperature-stabilized 99.5% pure Glycerin or specialized Silicone oil along with an internal top-venting rubber diaphragm plug. This allows internal pressure equalization and prevents pointer zero displacement during ambient temperatures exceeding 55°C.
For legacy infrastructure and European-designed units, G 1/2", G 1/4", or BSP threads are widely used. However, for oil and gas projects managed under API or US standards (e.g., in Kurdistan or southern oil concessions), 1/2" NPT or 1/4" NPT male threads are standard. We provide all international thread profiles with NPT, BSP, or Metric options.
Yes. As an OEM/ODM direct factory manufacturer, we customize dial scale layouts. We regularly manufacture dials featuring dual scales (e.g., Bar / PSI or KPa / PSI) with customized company branding, logos, and dual-language technical markings for engineering clearance in Iraq.
We provide full documentation packages required for Iraqi import clearance: ISO 9001 certificates, EN 10204 3.1 Material Traceability reports, Factory Calibration Certificates, Certificate of Origin (COO) legalized by the relevant Chamber of Commerce, and coordination for SGS/TÜV Verification of Conformity (VoC) testing.
Standard stainless steel pressure gauge orders of 1,000 to 5,000 units are produced within 15 to 20 days. Transit time via ocean shipping from Ningbo/Shanghai to Umm Qasr Port typically ranges from 22 to 28 days, ensuring reliable schedule planning for EPC contractors.
