How we create value

Clear technical ownership from inquiry to delivery

Our service philosophy is simple: protect the operation with product quality and create value through responsive support.

Application review

We clarify the well conditions, duty cycle, pressure, mobility, climate and site constraints before recommending a configuration.

Manufacturing control

Equipment is supported by a documented quality system, product testing and configuration review before dispatch.

Export coordination

We prepare the technical and commercial information needed for international procurement, logistics and project communication.

Quality and responsibility

Credibility comes from verifiable detail

SJ reports ISO 9001, HSE and API Q1 related quality credentials and maintains a product and service network serving oil and gas markets in China and overseas.

For a project-specific review, ask our team for the relevant configuration, available technical documents and delivery scope instead of relying on generic brochure language.

Buyer verification

Ask for the documents relevant to the selected configuration

Before order confirmation, an international buyer can request the product information needed for technical review. The appropriate package depends on the equipment and project scope.

  • Current product description and matched parameter table.
  • Configuration, interface and inspection requirements for the quotation.
  • Packing, delivery and export-document information relevant to the order.
  • Clarification of spare parts, commissioning and after-sales responsibilities.

Send the operating conditions and tender requirements through the inquiry page so the available documentation can be confirmed against the selected product.
