CNPC: geography and layout
CNPC's headquarters are in Dongcheng District, Beijing, while its operating assets are spread across China's oil and gas basins and overseas, so site contacts are rarely at head office.

Intrinsically Safe Mobile Phone for CNPC
CNPC is a Beijing-headquartered state-owned integrated energy group and parent of PetroChina, covering crude and gas production, refining and petrochemicals in China and overseas. Its Changqing field in the Ordos Basin is reported as China's largest oil and gas field. This page explains what to look for in an intrinsically safe mobile phone for CNPC, and where the IS-04Z1 stands against that list today.

WhereCNPC
Short answer. The SAMS IS-04Z1 is the intrinsically safe smartphone covered here for CNPC: pre-launch, designed for Zone 1 and Zone 21 (marking target Ex ib IIC T4), with certification in progress and no certificate issued.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

The organisation · CNPC
Working with China National Petroleum Corporation (CNPC): sites and classified areas
The main sites and the hazardous-area types a portable device is likely to meet at this organisation.
Sites and areas
- Changqing oilfield (Ordos Basin)
Classified areas
- Oil and gas production facilities
- Gas processing
- Refinery process units
- Petrochemical plants
Supplier approval · CNPC
How suppliers reach CNPC
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams. The Ex certificate and an organisation's own vendor or engineering approval are two separate timelines; SAMS is working towards both and holds neither today.

CNPC: projects and investment
In July 2013 CNPC and Eni signed a 4.2 billion dollar deal for a 20% stake in an offshore natural gas block in Mozambique, an example of its overseas gas investments.
CNPC: industry on the ground
In March 2014 the chairman announced that six business units would be opened to private investors, which means some service and equipment purchasing may sit with newer mixed-ownership entities.
CNPC: who works there
Its subsidiary Great Wall Drilling Company provides drilling services, so rig crews and service contractors are an important group of hazardous-area users within the CNPC family.
The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In CNPC. Field inspection at the Changqing oilfield in the Ordos Basin, gas processing rounds and petrochemical plant checks involve photographing equipment, reading tags and logging faults. A handheld designed as intrinsically safe could carry that on one device. The IS-04Z1 is designed for the purpose, though certification is still in progress.

Specifying an intrinsically safe mobile phone for CNPC
A short checklist for anyone writing or reviewing the specification, with the IS-04Z1 status against each point.
Check on the paper
- Marking
- Equipment group, category, protection concept, gas group and temperature class, matched to the area drawing.
- Certificate and schedule
- A certificate number, issuing body and the schedule of conditions, not a brochure claim.
- Standards edition
- The IEC 60079 or national standard edition the certificate was issued against.
Check for the IS-04Z1
- Marking target
- II 2 G Ex ib IIC T4: a target, not yet a certificate.
- Certificate status
- IECEx, ATEX, UKEX and NEC 500 in progress; none issued.
- Operator approval
- Separate from the certificate and handled with the site operator.
Questions · CNPC
Frequently asked questions
Can CNPC buy the IS-04Z1 today?
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
What does an intrinsically safe mobile phone for CNPC cost?
No price is published. While certification is in progress there is no list price and no committed lead time, and a supplier quoting a firm figure for an uncertified Ex handset is promising something it cannot stand behind. Indicative pre-launch pricing is issued in writing against a stated quantity and site.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
How does CNPC approve suppliers?
Supplier registration and equipment approval are run by the organisation itself; confirm current requirements with its procurement and HSE teams.
Is intrinsically safe the same as explosion proof?
Not exactly. Explosion proof is a broad everyday term; intrinsic safety is one protection concept, which limits energy so ignition cannot occur. Flameproof (Ex d) is a different concept that contains an explosion. The IS-04Z1 is intrinsically safe by design.
How do northern Chinese oilfields affect device choice?
Fields in northern and north-western China can see very cold winters and dusty, dry summers, so battery performance in cold, dust ingress protection and screen visibility in glare matter. Ask the oilfield for its operating temperature limits and any site restrictions on portable electronics.
What explosion-protection certificate do Chinese sites normally require?
China has its own explosion-protection certification scheme and marking, and operators usually expect equipment to carry the Chinese certificate in addition to any international ones. Confirm with the site and its certification body which approvals they accept before offering handheld devices.
Is a handset suited to wide inland fields like Changqing?
It can be, if the marking matches the area classification, battery capacity covers long shifts and the fleet can be managed centrally. Dust and winter cold need checking. IP68 is not explosion protection. The IS-04Z1 is not yet certified, so confirm with the site operator.
