Outstanding Product Advantages

- Strictly follows ASME B18.31.5 dimension tolerance, uniform round bend ensures perfect fit with standard pipes and pipe brackets

- High-strength carbon steel substrate delivers reliable clamping force for static pipe loads, good ductility and stable tensile property

- Zinc plated coating forms a protective barrier against oxidation and light corrosion, ideal for indoor use and mild outdoor atmospheric environments

- Smooth, clean threads without burrs, easy for quick field assembly, reduces the risk of thread galling during installation

- Flexible customization: custom bend width, leg length and thread length for non-standard special pipe diameters

- Consistent batch quality, each lot undergoes sampling inspection for dimension, plating thickness and thread check

- Can be supplied separately or pre-assembled together with nuts and washers to save on-site installation time

- Stable supply chain, continuous production schedule to support long-term framework orders for overseas clients

Every detail is controlled for field installation. Our ASME B18.31.5 Round Bend U Bolt Carbon Steel Zinc Plated features a smoothly rounded bend that avoids concentrated stress at the turning point, lowering the risk of fracture under sustained load. The electro zinc plating is evenly distributed over the whole surface, including inner thread valleys and the curved section, instead of only covering outer surfaces. If you have special chromate requirements, clear or yellow passivation options are available to match your local market standards.

Packaging, Shipment & Export Service

Item	Details
Packaging Mark	Custom shipping mark & size label
Shipment	Sea, air or express delivery
Order Form	Bulk order & framework contract acceptable
Inspection	Pre-shipment sampling inspection supported
After Service	Technical support for installation advice

Our export team is familiar with customs requirements of different countries. We can prepare all required documents neatly and mark batch and size information clearly on outer packages. Custom shipping marks are acceptable as your design. For large bulk orders, pallet packing with stretch wrapping will be adopted to prevent cargo shifting during sea transportation and reduce damage risk. We can cooperate with your nominated freight forwarder or recommend reliable logistics solutions according to your delivery schedule and budget.

Typical Application Scenarios

Our ASME B18.31.5 Round Bend U Bolt Carbon Steel Zinc Plated is widely used across a broad range of piping systems. Common applications include water supply pipelines, fire protection piping networks, HVAC pipe racks, mechanical equipment pipeline supports, factory process piping and building mechanical service systems.

It is widely selected by overseas pipeline contractors, fastener wholesalers, pipe support manufacturers and engineering material suppliers. For projects adopting American piping standards, this ASME compliant U bolt eliminates dimension mismatch risks and simplifies inspection and acceptance on site.

It works well in stationary pipe fixing scenarios where frequent disassembly is not required. Many customers combine this U bolt with pipe clamps and strut channels to build complete pipe support systems. If your project runs under US engineering codes, using ASME B18.31.5 certified fasteners helps you pass site inspection smoothly.

Rigorous Quality Control

Every batch of our ASME B18.31.5 Round Bend U Bolt Carbon Steel Zinc Plated goes through multi-stage quality checks. Raw carbon steel material will be verified before production. After bending, threading and plating, QC teams inspect bend geometry, thread integrity, plating adhesion and surface finish. We can provide test reports upon request to support your project documentation and third-party inspection.

Our inspection workflow covers incoming material check, in-process patrol inspection and finished product sampling. We keep batch records for traceability. If third-party inspection is arranged before shipment, our workshop and QC team will fully cooperate for measurement and appearance verification.
