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 Smartphone Supplier 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 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. Buyers searching for an intrinsically safe smartphone supplier for CNPC can take the datasheet and the certification schedule for the IS-04Z1 now; supply follows certification.

WhereCNPC
Short answer. An intrinsically safe smartphone for CNPC cannot be bought yet: the SAMS IS-04Z1 is pre-launch (certification in progress, no certificate issued), and the datasheet, certification schedule and safe-area evaluation units are available now.
Status: pre-launch. IECEx, ATEX, UKEX and NEC 500 certification is in progress and no certificate has been issued; launch is planned for Q4 2026. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

Supplier approval · CNPC
Becoming an approved supplier to 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: infrastructure
In 2018 the company announced gas storage facilities with a total capacity of 55.6 billion cubic metres in northern Henan province, to ease winter supply bottlenecks, adding underground storage and compression sites.
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.
The route · supply
Sourcing the IS-04Z1 for CNPC
Supply of the IS-04Z1 to CNPC starts only after certification, through authorised distributors. Until then a buyer can request the datasheet and the written certification schedule, and arrange a safe-area evaluation unit, which puts the site on the list for the right local channel at launch.
- 01
Request the datasheet
The technical specification, marking target and conditions of use, sent by email.
- 02
Ask for the certification schedule
Which certificates are in progress, in what order, and what is still to be confirmed.
- 03
Evaluate in a safe area
Evaluation units can be used for connectivity, MDM enrolment and workflow testing outside classified areas.
- 04
Register for launch
Tell us the site, zone, gas group and quantity so the right authorised distributor can contact you.
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 smartphone for CNPC cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
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.
How will SAMS supply CNPC?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
What language is expected on documentation for Chinese sites?
Chinese is the working language, so labelling, safety instructions and training for hazardous-area devices are normally expected in Chinese, with English accepted for some engineering discussion. Confirm the documentation language with the site's procurement and safety departments.
Is CNPC or PetroChina the right contact for supplying Ex phones?
PetroChina holds most of the operating assets, including refining, chemicals and gas, while CNPC is the parent group with other businesses such as drilling services. The right contact depends on the site, so ask the local oilfield or refinery safety and procurement teams which entity places the order.
Does CNPC accept IECEx documents for equipment approval?
CNPC runs its own supplier registration and equipment approval, so the answer depends on its current requirements and any national rules. IECEx documents help comparison. The IS-04Z1 has no certificate yet. Confirm requirements with CNPC's procurement and HSE teams before planning an evaluation.
