About Tangshan Dachuan Machinery Co., Ltd. - Drilling Machines & Tools Supplier in China

Based in China, Tangshan Dachuan Machinery Co., Ltd. lists seven active products across its catalogue. The company is classified under the “harbor” trust tier and focuses on drilling machines and tools, industrial machinery, and industrial pumps. Its product portfolio includes equipment designed for drilling fluid management and pump applications, reflecting the typical HS‑code families for earth‑moving and fluid‑handling machinery. The catalogue size of seven items indicates a targeted offering rather than a broad line‑up, emphasizing specialised solutions for oil‑field and tunnelling operations.

The specific items listed are a Mud Cleaning Machine, a Drilling Mud Desander, a TBM Slurry Separation Plant, a Linear Motion Shale Shaker, a Drilling Mud Mixer, a Centrifugal Pump, and a Mud Gun used in oil‑field drilling. These products fall under categories such as fluid separation, solids removal, mixing, and high‑pressure pumping, which are common components of drilling‑fluid circulation systems. Each product is identified by its functional name without additional HS codes in the supplied data, aligning with typical Chinese export listings for drilling‑equipment machinery.

Product Range and Specialties of Tangshan Dachuan Machinery Co., Ltd.

Tangshan Dachuan’s catalogue covers seven pieces of equipment that are standard in drilling‑fluid circuits. Mud cleaning machines and desanders are used to remove cuttings and reduce solids content; typical capacities range from 10 to 50 m³/h with mesh sizes down to 0.2 mm. The TBM slurry separation plant is a specialised system for tunnel‑boring‑machine operations, often designed for continuous operation at flow rates above 30 m³/h. Linear motion shale shakers provide high‑frequency, low‑amplitude vibration, with screen panels commonly offered in 0.5 mm to 2 mm apertures. Drilling mud mixers are sized to handle 5 - 20 m³ batches and feature agitators that meet API RP 13 specifications. The centrifugal pump is generally a cast‑iron or stainless‑steel unit with head ratings of 30 - 150 m water and flow rates up to 200 m³/h. Mud guns are handheld devices that deliver pressurised mud streams, typically rated to 0.5 - 2 MPa.

In the broader industry, such equipment is classified under HS chapter 84 (machinery) and often conforms to standards such as ISO 9001 quality management, API 650 tank construction, and ISO 14001 environmental management. Buyers frequently request data on material grades (e.g., ASTM A105 carbon steel for pump casings) and performance curves that meet API 13‑1 for mud‑system components.

Trade and Export Information - Tangshan Dachuan Machinery Co., Ltd.

China is a leading exporter of drilling‑fluid handling equipment, supplying oil‑field service firms in the Middle East, Africa, and South America, as well as tunnelling contractors in Southeast Asia. Products like mud cleaners, shakers, and centrifugal pumps are normally classified under HS codes 8421 (centrifugal pumps), 8424 (shakers), and 8479 (other machines). Importing countries often require certificates of conformity such as ISO 9001, CE marking for the EU, and API‑approved test reports for pressure equipment.

Typical export logistics involve 20‑ft or 40‑ft containers for smaller units (shakers, mud guns) and heavy‑lift shipping for large pumps or complete slurry‑separation plants, usually under FOB or CIF Incoterms. Chinese customs may request pre‑shipment inspection by CIQ, and buyers should be prepared for documentation that includes a commercial invoice, packing list, certificate of origin, and any required third‑party inspection reports. Seasonal demand peaks align with oil‑field drilling campaigns, influencing lead times and container availability.

Sourcing from Tangshan Dachuan Machinery Co., Ltd. - Buyer Guidance

When sourcing from Tangshan Dachuan, buyers should request detailed product datasheets that specify flow capacity (m³/h), pressure rating (MPa), material of construction (e.g., ASTM A105 or 304 SS), and any applicable API or ISO standards. Test reports for mud viscosity (ASTM D4642) and solids removal efficiency are common verification documents for mud cleaning machines and desanders.

Buyers are advised to confirm the supplier’s ISO 9001 certification and, if exporting to the EU, CE conformity for relevant machinery. It is prudent to ask for a performance curve for the centrifugal pump and a screen‑mesh verification report for the shale shaker. Prior to full order placement, a sample unit or on‑site demonstration can validate installation fit‑ment and operational reliability. Clarify the minimum order quantity, typical lead time (often 30‑60 days for standard models), and packaging details such as wooden crates with shock‑absorbing padding for heavy equipment.

What types of drilling‑fluid equipment does Tangshan Dachuan list in its catalogue?

The catalogue includes a Mud Cleaning Machine, Drilling Mud Desander, TBM Slurry Separation Plant, Linear Motion Shale Shaker, Drilling Mud Mixer, Centrifugal Pump, and a Mud Gun used for oil‑field drilling.

Are there standard specifications buyers should look for in these machines?

Typical specifications include flow capacity (10‑50 m³/h for cleaners, up to 200 m³/h for pumps), pressure rating (0.5‑2 MPa for mud guns, up to 150 m water head for pumps), and screen mesh size (0.2‑2 mm for shakers).

Which certifications are commonly required for drilling‑fluid equipment from China?

Buyers usually request ISO 9001 quality management, API 650 for pressure vessels, and CE marking for EU imports. Specific projects may also call for API 13‑1 compliance.

What HS code families do these products fall under?

The equipment is generally classified under HS chapter 84: centrifugal pumps (8421), shale shakers (8424), and other drilling‑fluid machinery (8479).

What is the typical minimum order quantity and lead time?

Lead times are commonly 30‑60 days for standard models, with minimum order quantities ranging from a single unit for shakers to a full set for slurry‑separation plants, depending on configuration.

How are the items packaged and shipped?

Smaller units are containerised in 20‑ft or 40‑ft containers, while larger pumps or complete plants are shipped on pallets or heavy‑lift frames, usually packed in wooden crates with cushioning and secured with steel strapping.

Can I request a sample or on‑site demonstration before placing a full order?

Yes, buyers can arrange for a sample unit or a field demonstration to verify performance, installation compatibility, and durability before confirming larger volumes.

What documentation should I expect with the shipment?

Standard export documents include a commercial invoice, packing list, certificate of origin, ISO 9001 certificate, and any third‑party inspection reports required by the destination country.
