Pipes, Tubulars & Pipeline Equipment
Casing, tubing, drill pipe and line pipe, with the fittings, flanges and accessories that connect them into wells and pipelines.
What this category covers
Tubular goods go into the well as casing and tubing, make up the drill string as drill pipe, and carry product as line pipe. We investigate sourcing across these groups, together with the fittings, flanges, gaskets and pipeline accessories that join them.
Quotations in this category are compared on size, wall thickness, grade, connection and quantity, so a complete specification matters more than any brand name. Where a project allows technically suitable alternatives, we say so in the comparison and leave the technical approval to you.
Equipment and parts we investigate
- Casing and tubing (OCTG)
- Drill pipe, drill collars and heavy-weight pipe
- Line pipe, seamless and welded
- Pup joints, couplings and crossovers
- Elbows, tees, reducers and caps
- Flanges, gaskets and fasteners
- Pipeline accessories such as pig launchers and receivers
These are examples, not a stock list, and they do not limit what we can investigate. If your equipment or part is not listed, send us your requirements.

Standards often referenced
These standards are common reference points when a requirement is written. Listing one here is not a statement that LB or any supplier holds a certificate or licence. If your requirement calls for certified or monogrammed products, say so in your RFQ and we will investigate whether suitable manufacturers can meet it.
- API Spec 5CT: casing and tubing
- API Spec 5L: line pipe
- API Spec 5DP: drill pipe
- ASME B16.5 and B16.47: pipe flanges
- ASME B16.9: factory-made butt-welding fittings
- ASME B31.4 and B31.8: liquid and gas pipeline systems
About Pipes, Tubulars & Pipeline Equipment
What details do you need to quote casing or tubing?
Outside diameter, weight or wall thickness, grade, connection type, length range and quantity for each size. If the order is for a specific well programme, include the casing programme or a summary of it.
Does it matter whether line pipe is seamless or welded?
Yes. The two are manufactured and specified differently. State which your project allows, with grade, wall thickness and any product specification level, so the quotation compares like with like.
Are you limited to the categories shown on this site?
No. The categories are examples of what we source. If your equipment or part is not listed, send us your requirements and we will investigate sourcing options.
Are you a manufacturer, and do you hold stock?
No to both. We are a sourcing company: we work with suitable manufacturers in China and primarily operate requirement by requirement, not from ready stock.
