Specification basis: The schedule below distinguishes industry geometry from order-specific requirements. Final dimensions, performance and price are defined in the approved quotation and drawing. Photographs identify the product family.
What is a u bolt pipe support?
A U bolt pipe support uses a curved threaded fastener with a base or structural attachment to retain a pipe at its support position. Its clearances and tightening arrangement determine how the pipe interacts with the supporting assembly.
Key dimensions and installation fit
Choose a U-bolt using the actual pipe OD, bend radius, leg spacing, thread length and hardware. Load ratings in another manufacturer’s table apply to that particular assembly and must not be transferred to an untested JINYI configuration. Compare related configurations: split pipe clamp, clamp pipe shoe.
How to specify the u bolt pipe support
Specify actual pipe outside diameter, coating or insulation allowance, bolt diameter, leg spacing and thread length. Identify whether the assembly is a hold-down, guide or fixed restraint. A U bolt should not be selected from pipe size alone.
Match the actual pipe outside diameter, contact arrangement and support elevation. Include the vertical, lateral and axial reactions, thermal movement and any insulation clearance. A component dimension does not establish support capacity; the clamps, welds, foundation and anchors form the complete load path.

Sizes and dimensional requirements
Use the named standard for standardized interfaces and the controlled drawing for custom dimensions. Confirm units, diameter datums, minimum finished thickness and any mating-component requirements. A catalogue dimension is not a universal tolerance, capacity or pressure rating.

Materials, inspection and documentation
Check contact dimensions, mounting-hole spacing, plate thickness and bolt details. For welded items, specify weld symbols, procedures and examination. For bolted supports, define the mating plate, fasteners and tightening requirements. Confirm coating and accessible maintenance surfaces before installation.
State the exact material designation and supplied condition, the controlled drawing revision and the required inspection reports before ordering. Separate material certification from dimensional checks and functional or pressure testing. Agree the acceptance limits for the ordered component and identify any additional witnessing, marking or packing requirements. Use the pipe support and casing manufacturing guidance to confirm fabrication and inspection requirements.
Installation and handling guidance
Check the base hole spacing and access for washers and nuts. Apply the tightening method stated in the assembly detail. Do not clamp a thermally moving pipe rigidly when the piping design requires travel or clearance.
Where the u bolt pipe support is used
- Pipe racks. Supporting or guiding lines at drawing-defined elevations.
- Vertical risers. Transferring the specified pipe reaction through an approved bearing arrangement.
- Plant maintenance. Replacing components with checked pipe interfaces and support reactions.
How to order a u bolt pipe support
Send the required configuration, material, quantity, destination and controlled drawing to JINYI. Identify changed dimensions, mating components, operating conditions and inspection scope. For a repeat order, include the previous approved revision and state any changes. The final quotation defines the supplied geometry, documentation, price and delivery terms.

U Bolt Pipe Support selection and quotation checklist
The U bolt fits around the pipe and attaches to the supporting structure. Specify the thread, leg length, base interface and required restraint, rather than assuming it replaces a sliding shoe. Use the photographed product form to identify the arrangement, then use the controlled drawing to define what will be supplied. Similar-looking components can have different end details, load paths or maintenance requirements.
U Bolt Pipe Support dimensions and tolerances
The first comparison for this u bolt pipe support is bolt spacing and pipe diameter. Mark the dimensions that control mating, alignment and installation space on the enquiry drawing. Give units for every value and identify the datum from which it is measured. If a dimension is critical, specify its individual tolerance and measurement method rather than relying on a general tolerance note.
Choose a U-bolt using the actual pipe OD, bend radius, leg spacing, thread length and hardware. Load ratings in another manufacturer’s table apply to that particular assembly and must not be transferred to an untested JINYI configuration. Review the selection schedule together with the final drawing and inspection requirements.
Prepare the material and interface information
For a u bolt pipe support enquiry, identify the required material designation and supplied condition. Describe the mating components, attachment method and environment. Include the operating temperature and any relevant pressure, movement or structural load. These inputs should describe the actual installation, including changes between normal operation, start-up and maintenance where applicable.
Specify coatings, surface finish and marking separately from the base material. If traceability is needed, identify the record required and how it must correspond to the delivered component. Agree whether inspection covers dimensions, material documentation, welds or functional testing; these are different checks with different acceptance criteria.
Custom u bolt pipe support quotation
Attach the latest drawing revision, required quantity and delivery destination when contacting JINYI. Highlight departures from the illustrated arrangement, including changed dimensions, connections, finish and packing. For repeat orders, reference the approved configuration and list changes explicitly so an earlier drawing is not assumed to remain current.
Compare quotations using the same geometry, grade, supplied condition, unit of supply and inspection scope. A piece, a segment and a complete assembly can represent different quantities. Confirm quantity discounts and delivery terms with the final quotation.

Questions to resolve before ordering
Which dimensions need checking first?
Start with bolt spacing and pipe diameter and the mating or mounting detail. Check nominal designations against measured dimensions, then review the installation envelope. Photographs help identify the form; the drawing provides the dimensional basis for acceptance.
What should the quotation include?
A u bolt pipe support quotation should identify the configuration, drawing revision, material, quantity, price basis and agreed inspection records. Keep these details together with the approved order so receiving inspection can compare the delivered product with the specified component.
