On May 12, 2026, Chinese pipe manufacturer Dalipal Holdings disclosed that it had secured its first batch of orders for the year from Kuwait Oil Company (KOC), totaling approximately 49,000 tonnes. Dalipal said the volume was 3.6 times what it received from KOC in the same period a year earlier. The filing confirmed the buyer and order volume; it did not identify the connection types, sizes, grades, or individual product quantities in the batch.
For oilfield service companies sourcing equipment for Kuwait, the announcement raises a practical question: once the main tubing or casing is specified, how do you source the pup joints, crossover subs, and tool connections that go with it? These items may account for only a small part of the order by weight, but each one has its own dimensions, material requirements, and connection details. A single accessory line can involve two different end specifications and a separate set of inspection documents.
In May 2023, Jiangsu Service Petroleum Technology Co., Ltd. (SWS) supplied Dalipal Pipe Company with 480 finished J55 tubing pup joints with EU connections. The order comprised four items:
| Tubing size | Grade and connection | Length | Quantity |
|---|---|---|---|
| 2⅜ in. | J55 EU | 6 ft | 140 |
| 3½ in. | J55 EU | 4 ft | 140 |
| 3½ in. | J55 EU | 8 ft | 100 |
| 3½ in. | J55 EU | 10 ft | 100 |
| Total | 480 |
The four lines show why an accessory order needs more detail than a total quantity. Even the three items with the same 3½-inch size, J55 grade, and EU connection were ordered as separate products because the lengths differed. A quote or packing list that combined them into a single 340-piece line would lose information the buyer needs to check the shipment against the order.
The 480-piece shipment was a separate historical delivery to Dalipal and was not part of the 2026 KOC order disclosed in May. Its EU connections were conventional threads. It illustrates how SWS supplied finished accessories to a tubular manufacturer, while the current KOC announcement provides the market context for why this kind of sourcing matters.
The same discipline applies to premium connections, with one additional question: who is authorized to machine the exact connection on the part being ordered? A pipe mill’s name, the pipe grade, and the connection designation are three different pieces of information. Even when a buyer specifies all three for the main tubulars, the accessory drawing should still identify the connection and end configuration for each component.
A crossover makes the issue easy to see. If one end must connect to the tubing and the other to a downhole tool, the supplier needs the exact designation, size, and pin or box configuration for both ends. A note that says only “Chinese premium thread” or lists a mill name leaves the machining scope open. When two different connections are specified on one part, the supplier also needs to review whether it can cover both ends under the applicable authorizations.
The same review applies to a float shoe or float collar body. The buyer should make clear whether the order is for a complete cementing tool or for thread machining on a customer-supplied body. In the second case, the supplier also needs to know the condition of the incoming part, which end requires machining, and whether any prior machining has already been completed. That information helps both sides agree on what the quotation actually covers.
SWS has separate machining experience with Baosteel BGT2 on 13⅜-inch and 9⅝-inch cementing tool components. This is an example of applying a specified Chinese premium connection to an accessory body. For a new order, SWS reviews the product form, connection designation, end configuration, and applicable licensor documents before confirming the scope. It is a separate machining reference, not a claim that the announced KOC batch used BGT2.
A useful inquiry lets the supplier identify the part, confirm both ends, and understand what must be delivered. For pup joints, crossovers, or cementing tool components, include:
Product and quantity: Identify each part and list different lengths or configurations on separate lines.
Material and dimensions: State the grade, nominal size, wall thickness or weight per foot, and the required length. If the drawing distinguishes overall length from effective length, retain that distinction.
Connection at each end: Use the full designation and show which end is pin or box. For a crossover, label the two ends on the drawing.
Supply scope and documents: Say whether you need a finished component or threading only. List any required material certificates, product conformity documents, inspection records, or third-party inspection requirements.
Schedule: Give the requested factory shipment date and, for threading-only work, the expected arrival date of the customer-supplied bodies.
For contractors buying from several suppliers, it is useful to settle these details while the main tubular order is being finalized. That gives the team time to check the accessory drawings, confirm the applicable connection authorization, and coordinate shipment dates before the parts are needed together.
If you are sourcing OCTG pup joints, crossover subs, or premium-threaded cementing tool components for Kuwait, send your item list or latest drawing to SWS. We can review finished supply and customer-supplied threading inquiries and confirm the applicable machining scope before quoting.
