Packing And Delivery

1 Packaging: Steel strapping for easy handling Wooden blocks or dunnage are put between the stacks to prevent organ shift while in shipping process. Surface treatment (optional): Black painting, rust preventive oil, plastic film. Galvanized piles can also be wrapped in a temporary protective plastic film to prevent scratching the surface. Customized packaging is available.

2 Delivery Information: Standard Lengths In Stock: 6m, 12m. Lengths: standard and custom. They Come with Sea Rail and Road Applicability Suitable for sea, rail or road transport, they are also strong enough on road application. The time of delivery is 15-30 days after receipt of payment, depending quantity and specification. Applicable to global export,with full document (Test Certificate, Packing List, Bill of Lading).

3 Handling precautions: Do not use slings or hooks without pads to come into direct contact with the pipe surface which may cause pipe deformation. Store in a cool,dry and well-ventilated place. To avoid rust before installation. Oversize and overweight cargo must comply with local shipping regulations.

FAQ

1. Why specify S275J0H over regular S275JR for piling works?

Core: Avoid brittle fracture. S275J0 delivers minimum 27J Charpy V-notch impact toughness at 0°C per J0 grade. Under heavy dynamic piling loads in stiff ground or cold climates, it prevents pipe cracking, unlike room-temperature-certified S275JR prone to catastrophic structural failure.

2. Secure weld integrity amid high-energy piling?

Core: Full non-destructive testing. All structural welds undergo 100% continuous ultrasonic (UT) inspection plus supplementary radiographic (RT) checks at pipe ends. Welding follows EN ISO 15614-1 to eliminate internal flaws and match weld strength to base metal.

3. Stop hot-dip galvanising (HDG) peeling during transit?

Core: Controlled silicon + Sa 2.5 blast cleaning. Restrict steel silicon to <0.03% or 0.14%–0.25% to avoid Sandelin-induced brittle zinc coating. ISO 8501-1 Sa 2.5 blasting ensures ductile, well-adhered galvanisation resistant to abrasion delamination.

4. Optimal surface finish for C5-M severe marine exposure?

Core: Glass-flake epoxy + full holiday testing. 400–500μm dry-film glass-flake epoxy over 50–80μm blast profile. Every pipe gets 100% high-voltage spark holiday inspection to seal pinholes and block chloride ingress.、

5. Prevent coating scratches during shipment?

Core: Non-metallic separation. Rubber/plastic spacers separate stacked pipes onboard; heavy-duty end caps guard against end impact. Fabric/nylon slings used exclusively for loading to eliminate metal-on-metal contact.
