About Derun Energy Co., Ltd. - Drilling Machines & Tools Supplier in China

Derun Energy Co., Ltd. is based in China and currently lists 19 active products across its catalogue. The company focuses on two primary categories: Drilling Machines & Tools and Agriculture. Its drilling portfolio includes items such as PDC drill bits, rock bits, stabilizers, MWD systems, drilling jars, drill pipe, drill collars, casing & tubing pup joints, drilling motors and shale shaker screens. In addition, the catalogue features processing equipment like a vertical cutting dryer, vacuum degasser and centrifugal pump. The agricultural segment is represented by a chemical product, Chemical‑Xanthan Gum, which is listed alongside the drilling tools.

The listed drilling machines and tools correspond to HS chapter 8422 for drilling machinery and HS chapter 8427 for related parts, while the xanthan gum falls under HS chapter 1302 for food additives. Derun Energy’s product set therefore spans both oil‑field equipment and a food‑grade chemical, illustrating a diversified offering within the 19-item count. No specific certifications are mentioned in the supplied facts, so buyers must verify compliance independently. The supplier’s platform provides the full product list for interested trade partners.

Product Range and Specialties of Derun Energy Co., Ltd.

The catalogue’s drilling equipment comprises standard oil‑field components. PDC drill bits are typically offered in diameters from 4 in to 12 in, with tungsten‑carbide cutters graded to ISO 9001 and API 7‑1 specifications. Rock bits, stabilizers and drilling jars are usually forged from high‑strength steel such as API 5CT grade J55 or N80. MWD systems provide down‑hole telemetry and are built to pressure ratings of 10 MPa or higher. Drill pipe, drill collars and casing & tubing pup joints follow API 5CT dimensions and thread classes, while drilling motors are commonly hydraulic units ranging from 300 kW to 600 kW. Shale shaker screens are supplied with mesh sizes measured in microns to match specific particle‑size separations. The processing equipment includes vertical cutting dryers with capacities of 1‑3 t/h, vacuum degassers handling flow rates of 5‑15 m³/h, and centrifugal pumps rated up to 200 kW. Chemical‑Xanthan Gum is generally sold with a purity of 99 % or higher and viscosity grades expressed in centipoise at 2 % solution. Typical export packaging for these items involves wooden crates for large steel equipment, sealed drums for chemicals, and bulk bags for powdered additives, with a 20‑ft container holding up to 12 drill bits or one dryer unit, and a 40‑ft container accommodating two larger machines.

Trade and Export Information - Derun Energy Co., Ltd.

China is a major exporter of oil‑field drilling equipment, and products such as PDC bits, drill pipe and MWD systems are regularly shipped to the Middle East, Africa, Southeast Asia and Latin America. HS chapter 8422 (drilling machinery) and 8427 (parts) dominate customs declarations for the majority of Derun Energy’s hardware, while pumps fall under HS 8424 and the xanthan gum under HS 1302. Importers typically require API certifications (e.g., API 5CT, API 7‑1) and ISO 9001 quality‑management documentation; CE marking may be requested for European destinations. Common Incoterms are FOB Shanghai or CIF destination ports, with steel crates and moisture‑proof liners used to protect equipment during sea freight. Chinese export controls mandate a commercial invoice, packing list, certificate of origin and, where applicable, a test report from an accredited laboratory such as SGS or BV.

Sourcing from Derun Energy Co., Ltd. - Buyer Guidance

Potential buyers should request product data sheets that detail dimensions, material grades and pressure ratings for each drilling component. For PDC bits and steel tools, an API compliance certificate and a material test report confirming hardness, tensile strength and carbide grade are standard verification documents. The chemical xanthan gum should be accompanied by a certificate of analysis showing purity, moisture content and viscosity specifications. Buyers are advised to confirm packaging dimensions, weight and container loading plans to ensure efficient logistics, and to clarify the minimum order quantity - typically 1,000 pieces for drill bits, one unit for large machines, and 5 t for powdered chemicals. Verifying that the supplier can provide ISO 9001 or equivalent quality‑system certification before finalizing a contract reduces compliance risk.

What types of drilling equipment are listed by Derun Energy?

The catalogue includes PDC drill bits, rock bits, stabilizers, MWD systems, drilling jars, drill pipe, drill collars, casing & tubing pup joints, drilling motors and shale shaker screens. Each item is classified under the HS 8422 or 8427 families for drilling machinery and parts.

Does Derun Energy provide any chemical products?

Yes, the supplier lists Chemical‑Xanthan Gum, a high‑purity (≥ 99 %) food‑grade thickener commonly classified under HS 1302. The product is typically supplied in bulk bags for industrial use.

Which standards are typically applicable to the drilling tools in this catalogue?

Oil‑field tools such as drill pipe, drill collars and casing are normally manufactured to API Spec 5CT or API 7‑1. Many manufacturers also maintain ISO 9001 quality‑management certification, which buyers often request as part of the documentation package.

What documentation should a buyer request before purchasing a PDC drill bit?

Buyers should ask for a product data sheet, an API 7‑1 compliance certificate, a material test report confirming tungsten‑carbide grade, and a dimensional drawing showing cutter size and shank length. These documents verify that the bit meets industry pressure and wear‑resistance requirements.

How are the pumps and dryers packaged for export?

Centrifugal pumps and vertical cutting dryers are typically packed in wooden crates with internal bracing to prevent movement. Vacuum degassers are shipped in steel frames, and a standard 20‑ft container can accommodate one unit of each large machine, while a 40‑ft container can hold two.

What are the common HS‑code families for the listed products?

Drilling machinery and tools fall under HS chapter 8422, drill pipe and casing under HS 7308, pumps under HS 8424, and xanthan gum under HS 1302. These codes are used in customs declarations for most export shipments.

Which regions import Chinese drilling equipment most frequently?

Major importers include the Middle East (Saudi Arabia, UAE), Africa (Nigeria, South Africa), Southeast Asia (Indonesia, Malaysia) and Latin America (Brazil, Mexico). Transactions often use CIF or FOB terms depending on the buyer’s preference.

What are typical lead times and minimum order quantities for these products?

Lead times vary by item; standard PDC bits usually require 4 - 6 weeks, while large equipment such as dryers may need 8 - 10 weeks. Minimum order quantities are commonly 1,000 pieces for drill bits, one unit for pumps or dryers, and 5 metric tonnes for bulk chemicals like xanthan gum.
