About Yancheng Jingcheng Petroleum Machinery Manufacturing Co., Ltd - Oil Field Machinery & Equipments Supplier in China

Yancheng Jingcheng Petroleum Machinery Manufacturing Co., Ltd is located in Yancheng, China and currently lists nine active oilfield equipment products. The catalogue includes high‑pressure choke manifolds, adjustable choke valves, plug valves, swivel joints and a complete wellhead Christmas tree system. Pressure ratings range from 3 000 psi to 15 000 psi and nominal sizes cover 1 in to 2 in bore dimensions. Each item is identified by its functional description rather than a model number, reflecting a focus on standard oilfield wellhead components. The supplier’s product set falls under the broader categories of Agriculture and Oil Field Machinery & Equipments as indicated in the source data.

The listed items correspond to HS‑code chapters commonly used for oilfield hardware, such as Chapter 84 (machinery) for choke manifolds and Chapter 84.79 for valves and fittings. In international trade, buyers typically expect compliance with API standards (e.g., API 6A for wellhead equipment, API 6D for gate and globe valves) and material certifications such as ASTM A105 for carbon steel bodies. Chinese exporters of similar equipment often provide CE marking or ISO 9001 quality management certificates upon request. Typical shipment configurations include steel‑framed pallets or wooden crates sized for 20‑ft or 40‑ft containers, with moisture‑resistant packaging to protect seals and joints during sea transport.

Product Range and Specialties of Yancheng Jingcheng Petroleum Machinery Manufacturing Co., Ltd

The catalogue comprises nine specific oilfield components: a high‑pressure wellhead choke manifold, a 2 1/16 in × 10 000 psi choke manifold, an API‑rated 2 1/16 in × 3 000 psi adjustable choke valve, a 2 9/16 in × 3 000 psi adjustable choke valve, a 1 in plug valve with 2 in connections (Fig 1502), a 2 in × 2 in × 15 000 psi wellhead plug valve, a 1 in swivel joint rated to 15 000 psi, a complete oilfield wellhead Christmas tree for drilling, and a 4 1/16 in × 10 000 psi choke manifold.

In the oilfield sector, choke manifolds and valves are typically supplied in carbon steel or alloy steel grades such as API 5L X65 for high‑pressure service. Standard performance specifications include pressure testing to 1.5 times the rated pressure, leak‑tightness to 0.1 MPa, and surface finish class 1.5 µm for valve seats. Buyers often select API 6A‑compliant designs that meet the 15 000 psi rating and incorporate ANSI B16.5 flanged connections. The Christmas tree assemblies usually consist of a series of valves, spools, and sealing elements designed for sequential opening and closing during drilling operations.

Trade and Export Information - Yancheng Jingcheng Petroleum Machinery Manufacturing Co., Ltd

China is a major exporter of oilfield wellhead equipment, with shipments directed to regions such as the Middle East, North Africa, Southeast Asia and Latin America. The products listed fall under HS codes 8421.21 (oilfield wellhead equipment) and 8481.80 (valves and fittings), which are subject to standard customs valuation and may require a Certificate of Origin for preferential duty rates under relevant trade agreements. Importers typically request API certification documents, material test reports, and a pressure test certificate prior to clearance.

Logistically, the nine items are sized for container loading; a 20‑ft container can accommodate up to four choke manifolds and associated valves, while a 40‑ft container is used for larger Christmas tree assemblies. Export packaging follows industry practice of using wooden crates with internal bracing and anti‑corrosion coating on exposed metal surfaces. Common Incoterms in this segment include FOB Yancheng port or CIF destination port, allowing buyers to arrange marine freight and insurance. Regulatory oversight may involve the receiving country’s petroleum safety authority, which often checks for compliance with API and ISO standards.

Sourcing from Yancheng Jingcheng Petroleum Machinery Manufacturing Co., Ltd - Buyer Guidance

Prospective buyers should request the supplier’s API 6A and API 6D compliance certificates, as well as material test reports conforming to ASTM A105 or equivalent alloy specifications. A pressure test report demonstrating at least 1.5 × rated pressure is standard for high‑pressure choke valves and manifolds. Samples of critical components such as valve seats or sealing rings can be requested for laboratory verification of hardness and corrosion resistance.

Before placing an order, verify the flange rating (ANSI class 150, 300, etc.) and the exact connection dimensions to ensure compatibility with existing wellhead infrastructure. Clarify the packaging details, including crate dimensions and whether moisture‑proof liners are used, to prevent damage during sea freight. Typical minimum order quantities are one unit per valve type, but lead times of 6‑8 weeks are common for custom‑rated equipment, with possible acceleration for stocked standard sizes.

What pressure ratings are available for the choke manifolds?

The catalogue includes choke manifolds rated at 10 000 psi (2 1/16 in) and 10 000 psi (4 1/16 in), as well as a high‑pressure version that is commonly supplied up to 15 000 psi for compatible wellhead applications.

Which API standards apply to the listed valves?

The adjustable choke valves and plug valves are typically designed to meet API 6A for wellhead equipment and API 6D for valve construction; buyers should request the supplier’s API certification documents to confirm compliance.

What are the typical material specifications for these products?

Most Chinese oilfield valves and manifolds are fabricated from carbon steel grades such as ASTM A105 or alloy steel X65, with surface treatments like phosphating or epoxy coating to enhance corrosion resistance.

How are the products packaged for export?

Standard export packaging uses reinforced wooden crates with internal bracing, each crate fitted with moisture‑resistant liners and protective padding around flanged connections to meet handling requirements for HS‑code 8421 equipment.

Which HS codes are relevant for customs clearance?

The choke manifolds and wellhead components fall under HS 8421.21 (oilfield wellhead equipment), while the plug and swivel valves are classified under HS 8481.80 (valves, taps, cocks and similar fittings).

What documentation should a buyer request before shipment?

Buyers should obtain API certification copies, material test reports (ASTM A105), pressure test certificates, and a Certificate of Origin; these documents facilitate customs clearance and verify product conformity.

What are typical lead times and minimum order quantities?

For standard size valves and manifolds, lead times are usually 6‑8 weeks from order confirmation, with a minimum order of one unit per valve type; customized pressure ratings may require longer production periods.
