If you are building a procurement list or filtering booth interests for the 19th China (Dongying) International Petroleum & Petrochemical Equipment and Technology Exhibition (CDYPE / Dongying Petroleum Equipment Exhibition), you usually do not need a rumour that “it is huge.” You need three readable facts: what the official site writes as the exhibit scope, how to read the dual-track theme, and which numbers are estimates only.
This page does one job. It restates the official exhibit theme and category list as a verification handbook. Missing detail stays labelled “check the official site.” We will not pad a fake complete picture.
Verify at http://dongying.banshanlvtu.com/. If the official site updates, that text wins.
CDYPE AI on www.cdype.ai is an unofficial third-party assistant. It is not the organizer’s website and not official support.
First: the dual track is a theme, not a guarantee
On the official “exhibit scope” section, the organizer states the exhibition theme as a “petroleum equipment + refining equipment” dual track (official Chinese: 「石油装备 + 炼化装备」双主线).
You can read it this way:
- Petroleum-equipment side: closer to exploration and development, drilling and completion, oil and gas production, gathering and transportation, offshore engineering, specialized materials, and engineering services — upstream through field-engineering equipment and technology.
- Refining-equipment side: closer to integrated refining and petrochemicals, basic chemicals, new chemical materials, and high-end specialty chemicals.
The dual track is a framework for “what this edition is talking about.” It is not a promise from this site that any given exhibitor will attend, and it is not a guarantee that each category has its own hall. Floor plans, exhibitor lists, and side-event detail follow later official notices — if and when the official site publishes them.
Official exhibit categories (summary restatement)
The following categories come from the official site’s exhibit-scope list. This site restates them in the official English labels where the same page already prints English. We do not invent extra product lines.
- Oil and Gas Exploration and Development Equipment
- Well drilling and completion equipment
- Oil and Gas Production Equipment
- Oil and gas gathering and transportation equipment
- Integrated Refining and Petrochemical Equipment and Basic Chemical Equipment
- New Chemical Materials and High-end Specialty Chemicals
- Offshore Oil and Gas Engineering Equipment
- Intelligent Oil & Gas and Digital Technologies
- Integrated Equipment for Green, Low-Carbon, and New Energy Applications
- Specialized Materials and Core Components for the Petroleum Industry
- Engineering Technology and Comprehensive Services
When you make a pre-show interest sheet, copy these 11 items as a checklist. Tick what you care about. Mark the rest “re-check on site / on the official page.” Do not let a third-party page guess “what else will be there.”
If a later official update adds, splits, or rewords a line, follow the live official list, not this snapshot.
370 categories, 17,000 varieties, area and visitors: how not to misread the numbers
The official introduction says the 19th edition is expected to cover more than 40,000 square meters, attract more than 500 enterprises, span 370 major categories and 17,000 varieties of petroleum and petrochemical equipment, and that visitor numbers are expected to exceed 60,000.
Read those figures as official-site introduction / estimate wording:
- They describe the organizer’s published scale expectation and category breadth.
- They are not a guarantee by www.cdype.ai or CDYPE AI.
- If the official site revises the numbers before the show, the revised official text wins.
Leaving the numbers incomplete is the honest move. You may use the official estimates for a rough trip plan. Do not rewrite an estimate as a completed statistic. Line-by-line scale reading: How to read official scale estimates. This page keeps the dual track and the 11 categories so the two posts do not swallow each other.
How this page differs from “what is CDYPE”
If you still need the name, edition, and “held since 2008 / eighteen consecutive editions” background, read the existing page: What is CDYPE / the 19th edition?. That page answers “what is it called, which edition.” This page answers how to read the exhibit theme and categories. It deliberately does not retell the full-name story, so the two posts do not swallow each other.
Dates and venue: When and where is CDYPE 2026?. How this site relates to the official source: How to verify official information.
Three checks you can run with the dual track
- Map your interest. Put your procurement or technology questions onto one or more of the 11 official categories.
- Open exhibit scope on the official site. See whether the wording changed, and whether extra notes were added.
- Exhibit or visit. The official page shows exhibitor registration and visitor registration entry points (buttons). Steps, fees, and deadlines follow the official site. This site does not invent a process.
If you want to turn “I care about drilling and completion / integrated refining” into a question you can paste into chat, ask the assistant on the site home. The assistant will not invent an unverified exhibitor list either.
Short FAQ
Does dual track mean there are only two kinds of exhibits?
No. Dual track is the theme skeleton. The official site then lists multiple equipment and technology directions (see the 11 items above). Theme is the frame; the categories are the published detail.
Will this site add “hot exhibitor picks”?
No. We will not dress an unverified list as a recommendation. Exhibitors and booth numbers: check the official site or on-site sources.
Are green/low-carbon and intelligent oil & gas a “third track”?
This site will not invent a third track. The official site lists them inside exhibit scope. Read them inside the dual-track theme the official page already gave, and check the original wording.
Can I put area and visitor figures in external materials?
If you quote them, mark the source as official-site introduction / estimate and keep the verification link. Do not write them as a CDYPE AI guarantee.
Is registration on this site?
No. Use exhibitor registration / visitor registration on the official site, and follow that site’s instructions.
