Common Challenges for Oil & Gas / Petrochemical Buyers in Sri Lanka
Traceability requirements
Pressure-boundary bolting requires heat-number traceable mill certificates that many suppliers can't produce.
Long-lead alloy grades
Specialty alloy stud bolts often have long lead times from unprepared suppliers.
How We Help
Certified stud bolt sets
Stud bolts, nuts, and washers supplied as matched sets with full mill test certification.
Grade planning
Early engagement on alloy grade requirements to manage lead time for project schedules.
Standards & Grades for Oil & Gas / Petrochemical Fasteners in Sri Lanka
The specifications oil & gas / petrochemical buyers most often quote. Our partner factories manufacture to the standard, grade and finish on your drawing or purchase order.
ASTM A193 B7 / B7M / B8 / B8M
Stud bolts for high-temperature and high-pressure flange bolting; B7M is the lower-hardness version for sour service.
ASTM A194 2H / 2HM / 8 / 8M nuts
Heavy hex nuts matched to A193 studs for pressure-vessel and pipeline flanges.
ASME B16.5 / B16.47 flange bolting
Stud length and diameter sets sized to flange class and nominal pipe size.
ASTM A320 L7 / L7M
Low-temperature stud bolts for cryogenic and cold-climate service.
Materials & Coatings
Cr-Mo alloy steel (B7)
Quenched and tempered alloy steel for most refinery and pipeline flange joints.
Stainless steel 304 / 316 (B8 / B8M)
For corrosive process fluids, offshore platforms and chemical plants.
PTFE / Xylan and hot-dip galvanized coatings
Fluoropolymer and zinc coatings extend stud life in offshore and coastal atmospheres.
