The catalogue spans Drilling Machines & Tools, Industrial Valves & Gauges, Tools & Instruments, Agriculture, Flanges, Industrial Pumps, Oil Field Machinery & Equipments and Elevators & Escalators, reflecting a diversified product portfolio that includes both mechanical and electrical components.

The supplier’s product list features items such as the API F Series Single Acting Triplex Mud Pump, API 3NB Series Mud Pump, API 7K Type WA‑T Safety Clamp, API 8A/8C SLX Side Door Elevator, Horizontal Centrifugal 32 PL Spray Pump and specialised items with HS codes - for example the API 16C Flexible Choke Coflex Hose (HS 7304.29, carbon‑steel with API 16C elastomer lining), the Reverse Circulation Fishing Magnet (HS 8505.19, NdFeB N52 core with carbon‑steel housing), the SE Type Elevator/Spider (HS 8428.10, carbon‑steel with high‑strength alloy components) and Elevator Links (HS 8431.31, stainless‑steel 304/316).

Product Range and Specialties of Dongying Lake Petroleum Technology Co., Ltd

The mud‑pump line follows API specifications commonly required for drilling rigs, with triplex designs delivering flow rates from 30 m³/h up to 120 m³/h and pressure ratings up to 35 MPa. Electric drive units such as the U L Certified NEMA D motor and the 10 Hp‑60 Hz‑900 rpm NEMA D motor comply with NEMA‑MG 1 standards for temperature class, insulation class and service factor, and are typically supplied with name‑plate data sheets and performance curves.

Hoses and couplings are listed under API 16C, where carbon‑steel bodies are lined with elastomeric seals to meet the API 16C‑5 standard for pressure resistance and temperature tolerance. The Reverse Circulation Fishing Magnet uses an N52‑grade NdFeB core, a grade that provides a pull force of approximately 500 kg in a 10 mm diameter shaft, a common benchmark for offshore fishing tools. Elevators and related components such as the SE Type Elevator/Spider and stainless‑steel Elevator Links are fabricated to ISO 9001 quality management procedures, with typical design loads ranging from 5 t to 30 t and compliance with ASTM A36 or ASTM AISI 304/316 material standards.

Trade and Export Information - Dongying Lake Petroleum Technology Co., Ltd

China is a global exporter of oil‑field machinery, with the majority of shipments destined for the Middle East, North Africa, Southeast Asia and South America. The HS‑code families represented in this catalogue - 7304 (metal hoses), 8428 (elevators and escalators), 8431 (elevator parts) and 8505 (electrical machines and parts) - are routinely inspected under the Chinese customs export inspection system and may be subject to third‑party verification such as API certification, CE marking or DNV‑GL type approval depending on the buyer’s market.

Typical export logistics involve 20‑ft or 40‑ft containers packed on wooden pallets or in steel‑framed crates, with Incoterms most often quoted as FOB Shanghai or CIF Dubai. Buyers usually request mill‑test reports, API data sheets and conformity certificates before shipment, and many importers in the target regions require compliance with local safety regulations such as Saudi Arabian SABIC standards or Brazilian ABNT norms for pressure equipment.

Sourcing from Dongying Lake Petroleum Technology Co., Ltd - Buyer Guidance

When sourcing from this supplier, buyers should request the specific API or ISO certificates that correspond to each product - for example API 6A for wellhead equipment, API 16C for flexible hoses, and NEMA‑MG 1 data sheets for electric motors. Mill‑test reports (MTR) confirming material grades, tensile strength and hardness, as well as dimensional inspection certificates for pipe, tubing and couplings, are standard documents that help verify compliance with industry specifications.

It is advisable to verify the HS‑code declared for each item against the product description, confirm packaging dimensions (e.g., 1 m × 0.8 m × 0.6 m wooden crate for a mud pump) and clarify minimum order quantities, which for heavy equipment typically start at a single unit but may increase for smaller accessories such as hoses or magnetic fishing tools. Sample testing of magnetic pull force, hose pressure rating and motor performance is common practice before final acceptance.

What oil‑field equipment categories does Dongying Lake Petroleum Technology list?

The catalogue includes mud pumps, safety clamps, side‑door elevators, spray pumps, flexible hoses, fishing magnets, electric motors, casing cutters, float equipment, drilling motors, pipe, tubing, couplings, screens and elevator components, each mapped to relevant HS‑code families.

Which certifications are available for the API 16C Flexible Choke Coflex Hose?

The product is listed with an API 16C designation; buyers should request the API 16C test report and any ISO 9001 quality‑management certificate the supplier holds for hose production.

What specifications should I check for the Reverse Circulation Fishing Magnet?

Verify the NdFeB N52 magnetic grade, the pull‑force rating (typically around 500 kg), the carbon‑steel housing thickness and the HS 8505.19 classification. Request a magnetic pull test report and material certification.

How are the NEMA D electric motors documented?

The motors comply with NEMA‑MG 1 standards; buyers should obtain the name‑plate data sheet, efficiency class, service factor and a test report confirming 10 Hp, 60 Hz and 900 rpm performance.

What are the typical HS‑codes for the elevator components?

Elevator/Spider units are recorded under HS 8428.10, while Elevator Links fall under HS 8431.31, both indicating carbon‑steel or stainless‑steel construction respectively.

What packaging is used for large oil‑field pumps during export?

Large pumps are usually crated in reinforced wooden boxes with internal bracing, loaded on 20‑ft or 40‑ft containers, and secured according to ISO 1496 container handling standards.

Which documents should I request before placing an order for pipe and tubing?

Ask for API 5L mill‑test reports, chemical composition analysis, dimensional inspection certificates and, where applicable, a CE or DNV type‑approval certificate for the specified grade (e.g., L80 or L90).
