Prioritise bend capability and coatings for large‑diameter OCTG work

What happened

Firstgas addressed an in‑line inspection anomaly on the DN750 Maui transmission pipeline by commissioning bespoke induction bends. Engineers redesigned and uprated bending equipment to produce three long‑radius, transition‑free induction bends for heavy‑walled X60 pipe, making the fix operationally specific rather than a simple off‑the‑shelf order. Watch whether this local capability is repeatable for future large‑OD repairs or remains a one‑off specialised job

Why the category manager should care

Treat reports of local induction‑bend success as a supply‑side signal: capability exists but is scarce, so verify supplier repeatability before relying on it for schedules

Key facts

• DN750 Maui transmission pipeline repair location
• Three long‑radius induction bends formed at 28 m radius
• Components formed from heavy‑walled 15.9 mm X60 PSL2 SAW pipe

What happened

Denso Australia published independent testing results for its Bore‑Wrap HDD protective system, including gouge resistance and adhesion tests against common parent coatings. The product resisted high gouge loads in both weld‑margin and standard configurations under third‑party protocols, providing a concrete basis for specifying coating protection in HDD projects. Buyers should watch for field trial reports and include test evidence in supplier prequalification

Why the category manager should care

Use the independent test data to raise minimum coating acceptance criteria in tenders, rather than relying on vendor claims alone

Key facts

• Tested for gouge resistance and adhesion using CSA Z245.20, NACE TM0215, ASTM D4541
• Resisted gouging forces up to 1250 kgF before disbondment in weld‑margin tests

What happened

Michels’ Direct Pipe trenchless method — a one‑pass combination of horizontal directional drilling and steerable microtunnelling — is being used on large offshore landfalls and has handled 30–60 inch carrier pipe diameters. The technique was applied on multi‑installation landfall projects that required tight schedules and 24‑hour coordination between crews, highlighting uptime and mobilisation dependencies. For buyers, the method illustrates why large‑OD projects need robust fabrication and logistics planning

Why the category manager should care

When projects specify trenchless landfall methods, expect tighter mobilisation windows and upgrade contractor prequalification to include integrated onshore‑offshore capability

Key facts

• Direct Pipe used for 30–60 inch pipe diameters
• Applied in multi‑installation large offshore landfall projects with continuous schedules

What happened

Elaflex Pacific highlighted engineered expansion joints and flexible pipe systems for high‑stress pipeline environments, noting manufactured sizes that cover a broad range up to very large diameters with fire‑rated inner pipes. Their product set targets thermal expansion, vibration and extreme conditions common in gas and offshore facilities, making expansion joints a non‑negotiable spec item for large systems. Procurement should capture these capabilities in spare‑parts and maintenance contracts

Why the category manager should care

Include expansion‑joint capability and certification in tenders for large pipeline systems to avoid late‑stage scope changes

Key facts

• Product range covers sizes from DN25 through DN1000, with engineered options reported up to D
• Stainless steel inner pipes provide high mechanical and temperature resistance and fire ratin
