CNPC: who works there
CNPC is the government-owned parent of listed PetroChina, created in 1999, which holds most of the group's exploration, refining, marketing, chemicals and natural gas businesses, so site buyers are often PetroChina units.

Explosion-Proof Mobile Phone Supplier for CNPC
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. Its Changqing field in the Ordos Basin is reported as China's largest oil and gas field. This page sets out how an explosion proof mobile phone supply route to CNPC will work for the IS-04Z1, and what is and is not available before launch.

WhereCNPC
Short answer. An explosion proof mobile phone 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.
Where things stand: the IS-04Z1 has not launched, and none of its four certification routes has produced a certificate yet. A buyer's engineering review is separate from the certificate. Certification status. Place facts reviewed October 2026.

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.

More about CNPC that matters for portable equipment
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.
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.
The term · explosion proof
What “explosion proof” means for a smartphone
“Explosion proof” is the phrase most buyers use for equipment that may be taken into a classified hazardous area. Strictly, it covers several protection concepts: a flameproof enclosure (Ex d) contains an internal explosion, while intrinsic safety (Ex i) limits electrical energy so that an ignition cannot start. Phones are normally intrinsically safe, because a flameproof handset would be too heavy to carry all shift.
The IS-04Z1 uses intrinsic safety, with a marking target of Ex ib IIC T4, and is designed for Zone 1 and Zone 21. It is pre-launch, certification is in progress and no certificate has been issued.
In CNPC. At oil and gas production facilities and refineries, 'explosion-proof' is everyday shorthand for different concepts. Flameproof Ex d protects fixed motors and enclosures, while intrinsic safety limits the energy of a portable device. A phone used on field or plant rounds is a handheld, so the IS-04Z1 is designed around intrinsic safety.

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.

Questions · CNPC
Frequently asked questions
Can CNPC buy the IS-04Z1 today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an explosion proof mobile phone 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.
Is the IS-04Z1 explosion proof or intrinsically safe?
It is intrinsically safe (marking target Ex ib IIC T4), which is the usual way to make a phone for hazardous areas. It is not a flameproof (Ex d) design, and certification is still 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.
