Kemasan Ekspor untuk Flensa Baja Paduan: Pencegahan Karat dan Perlindungan Laik Laut
Export packaging was completed for alloy steel flanges covering F11, F22 and F91 grades, multiple flange types and pressure classes. The packing route combined dry surfaces, temporary rust prevention, rigid face covers, moisture control, separation and seaworthy crate bracing.

Delivery highlights
Rust prevention before the crate is closed
Low-alloy steel can develop atmospheric rust when moisture, salt or condensation reaches bare machined surfaces. After final inspection, the flanges were cleaned and dried before an approved temporary rust preventive was applied to permitted areas. Gasket faces, RTJ grooves and weld ends received compatible protection that can be removed without damaging the surface.
Barrier wrap, VCI materials and desiccant were used according to the packing specification and expected transit conditions. Wet components were never sealed inside moisture-resistant wrapping.
Seaworthy protection for handling and ocean transport
Rigid covers protected raised faces and ring grooves. Individual flanges were separated, blocked and braced so their mass could not shift into adjacent components during truck, port or vessel handling. Crate members, lifting provisions and package markings were selected for the gross weight and destination requirements.
Before closure, quantities, markings and heat-number groupings were reconciled with the packing list. Receiving instructions identify the need for dry storage, periodic package inspection and preservation renewal when installation is delayed.
Information needed for a comparable RFQ
A comparable inquiry should identify the exact material specification and grade, governing standard and edition, NPC, kelas tekanan, tipe flensa, menghadap, jadwal bore atau pencocokan pipa, quantity and destination. For this project-news scope, the key reference points were ASTM A182 F11, F22 and F91, WN, SO, BL, SW and THD, Class 150–2500 Dan NPS 1/2–24; large-diameter NPS 26–60 when ordered.
State the required EN 10204 certificate type, keterlacakan nomor panas, PMI extent, batas kekerasan, dimensional report, NDE method and acceptance standard, third-party witness points, packing method and required delivery date at quotation stage. Early definition allows manufacturing, inspection and document schedules to be reviewed together.

Pertanyaan yang sering diajukan
Should alloy steel flange faces be painted?
Permanent paint should not be applied to sealing faces or RTJ grooves unless an approved removable system specifically allows it.
Is VCI alone enough for ocean shipment?
No single product is sufficient by itself. Dryness, barrier integrity, desiccant, duration, climate and crate design must be considered together.
What should be checked when the shipment arrives?
Check crate condition, moisture ingress, item count, markings, preservation and the condition of sealing faces and weld ends before storage.
