Dalipal’s 2026 Saudi Aramco Milestones: From Trial Order to Supplier Approval

In January 2026, Chinese pipe manufacturer Dalipal Holdings announced that its products had completed a trial order issued by Saudi Aramco and met the required test criteria. On May 12, Dalipal reported a second milestone: it had received formal confirmation of supplier approval from Saudi Aramco. The two filings describe the progression from a trial order to supplier qualification. They do not disclose the trial volume, steel grades, or connection designations, or announce a subsequent commercial order.

The announcements offer a useful view of how a Chinese pipe manufacturer can enter a major Middle Eastern supply chain. They also raise a more specific question for oilfield service companies: once a project approves its main tubulars and specifies a premium connection, how should the buyer source the pup joints and crossover subs that go with them?

That question comes up even when the accessory order is small. The pipe supplier, the machining shop, and the finished component supplier may have different responsibilities. A buyer who identifies those responsibilities at the inquiry stage can compare quotations on the same basis and see early which documents still need to be arranged.

Three checks before placing a premium connection accessory order

First, confirm the main tubular specification. Record the pipe manufacturer, steel grade, nominal size, weight or wall thickness, and full connection designation. These details should come from the approved project documents. The name of the mill alone does not tell an accessory supplier which connection to quote. If the project permits several options, identify the one that will actually be used on the string before releasing an accessory drawing for manufacture.

Second, confirm the scope of machining. Check the connection at each end of the accessory and identify who will machine it. If a crossover has two different proprietary connections, review each end separately, including the applicable authorization and product scope. For a finished component order, clarify whether one supplier is responsible for the entire part or coordinates part of the work with another processor. For a threading-only order, show which operations the incoming body has already undergone and which end still needs machining.

Third, agree on the documents required for the finished item. A machining authorization supports the review of the shop’s permitted work. The material and conformity documents requested for a shipment serve a different purpose: they identify the material or components actually supplied. If the project requires an inspection record or third-party witness, specify that at the inquiry stage so the supplier can confirm what it can provide and allow time for the inspection.

An SWS delivery case: Two BGT3 and CBS3 crossover configurations in one order

A March 2026 delivery note from Jiangsu Service Petroleum Technology Co., Ltd. (SWS) records two configurations of finished 4½-inch, 12.6 lb/ft, L80-13Cr crossover subs, each 1.5 m long. The material, size, and length were the same across both lines. What changed was the connection assigned to the box and pin ends.

Writing “26 BGT3/CBS3 crossovers” would give a supplier the right total and the names of both connections, but it would leave out the direction and quantity split. The order needed 12 BGT3 box × CBS3 pin crossovers and 14 CBS3 box × BGT3 pin crossovers. A procurement team needs that distinction on the drawing, purchase order, and shipment list to check that it has received the configuration needed at each interface.

This was a separate SWS delivery, unrelated to Dalipal’s Saudi Aramco trial or supplier approval. The delivery note documents the finished crossover configurations. For any new order, the machining scope for each connection must be confirmed against the applicable authorization and project requirements.

What to send with a Saudi project inquiry

If you are sourcing crossover subs or pup joints for Saudi Arabia or elsewhere in the Middle East, start with the latest drawing and an item list. For each line, identify the material grade, tubing size and weight or wall thickness, length, exact connection at each end, pin or box configuration, and quantity. For a crossover, it also helps to identify the mating component at each end so the supplier knows which side connects to the tubing and which side connects to the tool.

State whether the inquiry covers finished components or customer-supplied bodies, and include the required factory shipment date. If your project has its own supplier approval, authorization, inspection, or document requirements, include them with the inquiry. SWS can review the drawings and confirm the scope it can offer before quoting.
