Double Studded Adapter (dsa)
The Double Studded Adapter (DSA) from Dongying Lake Petroleum Technology Co., Ltd is a flanged connection component designed to join two piping systems with threaded studs on both ends. It is manufactured in standard sizes to match ASME B16.5 and EN 1092-1 flange dimensions, enabling compatibility with industrial pipeline networks. The adapter is machined from carbon steel or low-alloy steel, with no material grade specified in the listing.
Typical applications include oil and gas pipelines, chemical processing units, and water treatment plants where high-pressure fluid transfer requires leak-proof flange interfaces. The design allows for alignment correction between mismatched flanges and reduces stress on connected equipment. Wall thickness and bore diameter follow standard industry tolerances for Class 150 and Class 300 pressure ratings, though exact ratings are not confirmed.
This product is sourced by industrial procurement teams for maintenance, retrofitting, or new plant construction. Buyers typically require certification of material traceability and pressure testing. Packaging is in protective cartons with rust inhibitors. No MOQ, lead time, or incoterms are provided. Buyers must confirm all trade terms directly with the supplier, as no commercial data is listed.

| Typical material | Carbon steel ASTM A105 or low-alloy steel ASTM A182 F22, standard for pressure fittings |
| Typical pressure rating | Standard ratings for DSA fittings are Class 150 or Class 300 per ASME B16.5 |
| Typical flange face type | Raised face (RF) or flat face (FF), as per ANSI/ASME B16.5 |
| Typical stud size | Standard stud diameter ranges from M16 to M64, depending on flange size |
| Typical stud length | Typical stud length is 1.5 times the flange thickness plus 20 mm for nut engagement |
| Typical bore diameter | Bore diameter matches the pipe nominal diameter, with tolerance ±0.5 mm |
| Typical thread type | ISO metric external threads, per ISO 724 or ASME B1.1 |
| Typical finish | Anti-rust oil coating or bare metal; galvanized or painted finishes not confirmed |
| Typical testing | Hydrostatic pressure test at 1.5x working pressure is standard for pressure-rated fittings |

Sourcing Double Studded Adapter (DSA) from Dongying Lake Petroleum Technology Co., Ltd - China Import Guide
Before ordering, confirm the material grade and pressure rating of the DSA fitting. Request material test reports (MTRs) and pressure test certificates if used in high-risk environments. Verify flange face type and bore diameter against your existing piping. Do not assume compatibility without physical or dimensional verification.
Lead time, incoterms, and payment terms are not listed and must be confirmed directly. Packaging is likely in sealed cartons with rust inhibitors, but ask for moisture protection details if shipping long distances. Incoterms such as FOB Qingdao or CIF are common but unconfirmed. Buyers should negotiate payment terms like LC at sight or TT against documents.
For quality control, inspect for surface cracks, thread damage, and flange alignment. Use a micrometer to check bore diameter and stud length. Confirm that the finish is uniform and free of rust spots. Retain samples for reference. Request batch-specific documentation for traceability, especially if the product is used in regulated industries like oil and gas.
