About Tianhe Oil Group Huifeng Petroleum Equipment Co., Ltd - Drilling Machines & Tools Supplier in China

China hosts the catalogue of Tianhe Oil Group Huifeng Petroleum Equipment Co., Ltd, which lists five active products in the drilling equipment segment. The supplier’s catalogue is limited to five distinct items, all related to oil‑field drilling hardware, and falls under the broader categories of Heavy Machinery and Drilling Machines & Tools. Each product is identified by its functional name without additional sub‑variants, indicating a focused product line rather than a broad assortment. The supplier is classified as an imported tier with a harbor trust level, suggesting it operates through established import channels for downstream buyers.

The listed products include PDC bits, a drill collar, standard drill pipe, heavy weight drill pipe, and a stabilizer. PDC bits are polycrystalline‑diamond‑compact cutting tools used for high‑rate penetration in hard formations. The drill collar and both types of drill pipe provide weight on bit and torque transmission, while the heavy weight variant adds extra axial load for deep wells. Stabilizers are inserted to maintain borehole trajectory and reduce vibration. All items are typical steel‑based oil‑field components that conform to the engineering standards commonly applied in the sector.

Product Range and Specialties of Tianhe Oil Group Huifeng Petroleum Equipment Co., Ltd

The catalogue’s five items cover the core drilling string hierarchy. PDC bits are offered in common diameters from 4 in to 12 in and cutter grades ranging from 12 mm to 14 mm, matching the performance levels required for sandstone to carbonate formations. Drill collars generally conform to API Specification 7‑2, with wall thicknesses between 0.8 in and 1.2 in and grades such as J55 or N80. Standard drill pipe aligns with API 7‑1, typically supplied in lengths of 6 m to 12 m, nominal outer diameters of 4.5 in to 9 in, and strength grades like K55, N80, or P110. Heavy weight drill pipe follows the same API 7‑1 family but with increased wall thickness (up to 1.5 in) to provide additional weight on bit. Stabilizers are usually API 7‑3 compliant, featuring a central mandrel of 4 in to 6 in diameter and three to five rubber or steel sleeves for borehole conditioning.

Trade and Export Information - Tianhe Oil Group Huifeng Petroleum Equipment Co., Ltd

China is a leading exporter of oil‑field drilling equipment, with the majority of shipments destined for the Middle East, West Africa, and Latin America where offshore and onshore drilling activity remains high. Buyers typically import these components under HS chapter 84 (machinery) and HS chapter 73 (iron and steel products), and they often require compliance with API specifications and ISO 9001 quality management systems. Export logistics commonly use 20‑ft or 40‑ft containers packed in wooden crates or steel frames to protect against corrosion during sea transit. Incoterms such as CIF or FOB are standard, and customs authorities in importing countries frequently request a mill test report, product data sheet, and declaration of country of origin. Chinese manufacturers of drilling hardware also observe the Export Control regulations that restrict certain high‑strength steel grades without proper licensing, so verification of export licences may be necessary for some markets.

Sourcing from Tianhe Oil Group Huifeng Petroleum Equipment Co., Ltd - Buyer Guidance

Purchasers should request a complete product data sheet that lists API specification numbers, material grades, dimensions, and pressure ratings for each item. Mill test reports (MTR) and material certificates confirming compliance with API 7‑1, 7‑2 or 7‑3 and the relevant steel grade are standard documents that help verify quality. Because PDC bits are performance‑critical, buyers often ask for laboratory test results such as penetration rate (ft/hr) and cutter wear data under specified formation parameters. Samples or pilot runs are advisable before committing to full‑scale orders, and any deviation from the advertised API grade should be clarified in writing. Verification of ISO 9001 certification, if claimed, provides additional confidence in the supplier’s quality management system.

What drilling equipment does Tianhe Oil Group Huifeng Petroleum Equipment Co., Ltd list in its catalogue?

The catalogue includes five items: PDC bits, a drill collar, standard drill pipe, heavy weight drill pipe, and a stabilizer, all intended for oil‑field drilling applications.

Which industry standards are typically applicable to the drill pipe and drill collar offered by this supplier?

Drill pipe and drill collar normally follow API Specification 7‑1 and API Specification 7‑2 respectively, with steel grades such as K55, N80, P110 for pipe and J55 or N80 for collars.

What documentation should a buyer request before purchasing PDC bits?

Buyers should ask for a product data sheet, API specification reference, cutter grade details, and laboratory test results on penetration rate and cutter wear.

Are there typical certifications that buyers should verify for these drilling products?

Commonly required certifications include API compliance (7‑1, 7‑2, 7‑3), ISO 9001 quality management certification, and a mill test report confirming the steel grade and mechanical properties.

What are the usual packaging and shipping methods for these drilling components?

Items are usually crated in wooden or steel frames and loaded into 20‑ft or 40‑ft containers; shipping terms often use CIF or FOB, with protective coatings applied to prevent corrosion.

Which global regions most frequently import Chinese drilling equipment like that supplied by Tianhe?

The primary import markets are the Middle East, West Africa, and Latin America, where onshore and offshore drilling projects drive demand for drill strings and bits.

What size and length options are typical for the drill pipe and heavy weight drill pipe listed?

Standard lengths range from 6 m to 12 m, with nominal outer diameters between 4.5 in and 9 in; heavy weight drill pipe features thicker walls to increase weight on bit.

How can a buyer verify the quality of the stabilizer before shipment?

Request the stabilizer’s product data sheet, API 7‑3 compliance certificate, and a mill test report showing the material grade and sleeve hardness.
