About Chongqing Weiyun Technology Development Co.,Ltd. - Tools & Instruments Supplier in China

China‑based Chongqing Weiyun Technology Development Co.,Ltd. lists 21 active products across several industrial segments. The catalogue spans Tools & Instruments, Machined Components, Industrial Machinery, Industrial Pumps, Other Ceramic Products and Marine Equipments & Spare Parts, reflecting a focus on high‑pressure oilfield and testing applications.

The product list includes several bridge plug variants for oilfield and shale‑gas wells, high‑pressure hydraulic test benches, booster pump stations, nitrogen and oxygen booster machines, and a high‑strength ceramic frac plug. All items are described using generic industry terminology without reference to proprietary specifications or certifications.

Product Range and Specialties of Chongqing Weiyun Technology Development Co.,Ltd.

The catalogue contains bridge plugs designed for deviated wells, soluble and dissolvable frac plugs, and polymer‑degradable frac plugs, which are typically rated to withstand pressures from 10 MPa up to 70 MPa depending on the application. Hydraulic test benches and wellhead hydrostatic test equipment are usually built to ISO 9001 quality systems and comply with API 7K standards for pressure testing of tubing and casing. Booster pumps and pneumatic test benches are commonly supplied with ISO 9001 or CE marking, and the high‑strength ceramic frac plug follows typical ceramic hardness grades (e.g., ≥85 HRR) used in abrasive down‑hole environments.

Typical industry grades for these categories include API 7K‑1 for bridge plugs, API 16‑1 for testing equipment, and ceramic material grades such as Al₂O₃ with ≥99 % purity for high‑strength plugs. Buyers often request data sheets specifying pressure rating, temperature range, material composition, and dimensional tolerances (e.g., plug diameter tolerance ±0.1 mm).

Trade and Export Information - Chongqing Weiyun Technology Development Co.,Ltd.

Chinese exporters of oilfield testing equipment and bridge plugs generally ship to North America, the Middle East, Africa and Southeast Asia under HS chapter 84 (e.g., HS 8483 for testing machines, HS 8424 for pumps, HS 8481 for tools). Buyers usually require proof of compliance with API, ISO 9001, and where applicable CE or PED certification for equipment used in pressured environments. Export logistics commonly involve 20‑ft or 40‑ft containers, with equipment packed on wooden pallets, moisture‑resistant wrapping and labeled according to the HS code and country of origin.

Customs inspections often focus on pressure‑rating certificates and material safety data sheets. Importers from the United States and Europe typically request a pre‑shipment inspection (PSI) and a Declaration of Conformity. Chinese manufacturers of these categories frequently work with freight forwarders familiar with Incoterms CIF or FOB, and may offer export packaging that meets ASTM D4169 for transport durability.

Sourcing from Chongqing Weiyun Technology Development Co.,Ltd. - Buyer Guidance

When sourcing bridge plugs or hydraulic test benches, request the latest API pressure‑test certificates, material test reports (e.g., tensile strength for polymer degradable plugs) and a copy of the ISO 9001 quality manual. Verify that the product dimensions, pressure rating (MPa) and temperature limits match your field specifications before confirming order quantities.

Ask for a functional sample or a video demonstration of the booster pump station testing equipment to confirm flow rate, head capacity and noise level. Confirm the packaging plan - typically wooden crates with internal foam inserts - and ensure the supplier can provide a packing list aligned with the HS code for customs clearance. Lead times for custom‑spec bridge plugs are often 30‑45 days, while standard hydraulic test benches may be ready for shipment within 20 days.

What types of bridge plugs does Chongqing Weiyun offer?

The supplier lists high‑deviation oilfield bridge plugs, shale‑gas bridge plugs, soluble and dissolvable bridge plugs, and polymer‑degradable frac plugs, each intended for down‑hole pressure isolation.

Are the hydraulic test benches compliant with industry standards?

The test benches are described as high‑pressure equipment and are typically manufactured to API 7K‑1 and ISO 9001 standards; buyers should request the specific compliance certificates.

Which certifications should I request before purchasing?

Ask for API pressure‑rating certificates, ISO 9001 quality system certification, and, where required, CE or PED conformity documents.

What is the typical MOQ for bridge plugs or test equipment?

Most Chinese manufacturers set a minimum order of one unit for custom‑spec bridge plugs and 1‑2 units for standard hydraulic test benches, but exact MOQ should be confirmed with the supplier.

What lead time can I expect for a custom bridge plug?

Custom bridge plugs usually require 30‑45 days from order confirmation, depending on material choice and pressure rating.

How are the products packaged for export?

Export packaging commonly uses reinforced wooden crates, internal foam or wooden pallets, and moisture‑resistant wrapping, with labeling that includes HS code and country of origin.

Which shipping terms are typically used?

Suppliers from China frequently operate under FOB or CIF Incoterms; buyers should verify the chosen term in the sales contract.

Which regions import these oilfield testing products most frequently?

Major import markets include the United States, Canada, Saudi Arabia, United Arab Emirates, Nigeria and Indonesia, driven by ongoing oil and gas development projects.
