How to order fluorocarbon coated stud bolts?

Orders should specify details like size, length, nut type, thread class, material grade (e.g., ASTM A193 Gr.B7 - A194 Gr.2H), coating type, and color. Example: Stud Bolt 5/8"x80mm + 2 Heavy Hex Nuts, ASTM A193 Gr.B7, Fluorocarbon Coated blue.

What is the recommended nut for ASTM A193 Grade B7 studs?

For ASTM A193 Grade B7 studs, the nuts must conform to the ASTM A194 specification. A194 Grade 2H nuts are the most commonly paired option unless specified otherwise by a project engineer.

AI-Powered supplier vetting

SummaryThe supplier is a pipe fitting and flange manufacturer and authorized dealer serving pipeline-related industries. It demonstrates broad customization, OEM and ODM services, 3D software design capability, 13 R&D engineers, and evidence of new products during the past year. Production-related evidence includes hydraulic, EDM CNC cutting, heat-treatment, material-testing, and spectrometer equipment, with documented finished-product inspection procedures. ISO9001:2015, ISO45001:2018, and ISO14001 certifications are reported. Service management procedures cover supplier assessment, corrective and preventive actions, and customer complaints. However, the supplier has no valid manufacturing-capacity contract with associated subcontractors, no overseas warehouse, showroom, agent, or branch, and no SDK. Customer references include named oil, energy, and industrial organizations, but no Fortune 500 cooperation is reported.

Supplier typeThe supplier is described as a pipe fitting and flange company that also acts as an authorized dealer, serving electric power, metallurgy, city gas, heat networks, shipbuilding, and other pipeline engineering applications. This indicates a manufacturer-led industrial supplier with distribution activity.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 management-system certificates. These explicitly demonstrate certification coverage for quality, occupational health and safety, and environmental management.

After-Sales capabilityWritten and followed procedures are reported for service-capability assessment, corrective and preventive actions, and customer complaints. The supplier also reports training and equipment installation services and lead times within 15 working days in both peak and off-season, but lacks overseas warehouses, showrooms, agents, and branches.

R&D capabilityThe supplier reports 3D software design services, ODM capability, 13 R&D engineers, and new products during the past year. It also provides multiple forms of design customization, although no SDK is available.

Production capacityProduction evidence includes hydraulic machinery, EDM CNC cutting, heat-treatment equipment, universal material testing, and direct-reading spectrometer equipment, plus uniformly followed finished-product inspection instructions. The supplier also reports in-stock capability and 10 qualified service-capability suppliers, but lacks a valid manufacturing-capacity contract with associated subcontractors.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports custom design support to ASME VIII, ASME B31.3, and ASME B31 requirements, supported by 3D design services.

Client casesThe supplier names ARAMCO, SADRA, SWCC, PDO, OQ, ADAMA, DOWL, and Sonatrach as clients or organizations whose approval it has received. It reports no Fortune 500 cooperation, so the evidence supports established industrial customer experience but not Fortune 500 coverage.

Product Q&A

Q:What is Xylan coating?

Xylan is a family of fluoropolymer coatings designed to provide corrosion protection, lubrication, wear resistance, and non-stick properties. It offers benefits like anti-rust (resistant up to 3900 hours in salt spray tests), sustainability, lower maintenance costs, and low torque friction.

Q:Is Xylan the same as Te-flon?

No. Xylan and Te-flon are both brands of PTFE coatings. While they may have similar properties, they are not identical, and variations exist that make each suitable for different applications and environments.

Q:Is Xylan suitable for fasteners?

Yes. Xylan includes fastener-class coating systems designed to improve performance and longevity. It can be applied via dip-spin and spray methods, making it suitable for small screws up to large stud bolts.

Q:What is Xylan Blue?

Xylan Blue, or PTFE Blue, refers to coating B7 Stud Bolts and Nuts for the Petrochemical industry. The specific product is usually Xylan 1424 or Xylan 1070, but it is best to clarify with the end user or technical advice.

Q:What additional coating types can you supply?

We supply various coated stud bolts including Zinc + Fluorocarbon/PTFE, Cadmium + Fluorocarbon/PTFE, Zinc Nickel + Fluorocarbon/PTFE, Zinc Plating + Xylan 1424 Blue, and Xylar 2 + Xylan 1070 Blue.
