Preparation & fabrication

Industrial fabrication and specialty machining

From part requirements to finished equipment.

ACS coordinates industrial fabrication and specialty machining for shafts, flanges, specialty alloy work and pipe spools built to project requirements under ASME B31.3. Fabrication, surface preparation, coatings and stainless finishing are reviewed together around the drawing and scope of supply.

Specialty machining

Parts up to 36 inches in diameter and 20 feet in length.

ASME B31.3 pipe spools

Drawing-based spool fabrication and coordinated finishing.

Coordinated finishing

Bring fabrication and coating or lining requirements together.

CAPABILITIES

Shafts, flanges and pipe spools

Shafts & flanges

Machining of shafts and flanges, coordinated with the fits, tolerances and finish required by the assembly.

Common uses

  • Shaft assemblies and mating flanges.

What matters for your part

Alloy, drawing revision, critical fits, tolerances and finishing allowances.

Pipe spools

Pipe spools built to project requirements under ASME B31.3.

Common uses

  • Process piping with coating or lining requirements.

What matters for your part

Drawing, material, connections, fabrication scope and inspection requirements.

Specialty alloy work

Fabrication coordinated with preparation and finishing.

Common uses

  • Process equipment components that need both fabrication and a protective finish.

What matters for your part

Material supply, machining and welding scope, quantities and coating or lining requirements.

QUOTE INFORMATION

What to include in your inquiry

Drawing & material

Provide the drawing revision, alloy, quantity and dimensional requirements. Identify critical fits and tolerances.

Scope of supply

Clarify who supplies material and whether the work includes machining, welding, pipe-spool fabrication or a combination.

Finishing & inspection

Specify the coating or lining, areas requiring masking, dimensional checks and documentation so finishing allowances can be addressed before manufacture.

ONE PROJECT, COORDINATED SCOPE

Plan fabrication and finishing together

Bring the drawing, fabrication requirements and protective finish to ACS together. Coordinating these steps can reduce supplier handoffs, freight transfers and scheduling friction.

Address finishing before manufacture

Coating thickness, thread masking, sealing faces, weld condition and internal access affect the finished part. Include them at quotation so fabrication and finishing allowances can be reviewed together.

Define responsibility clearly

The quote establishes material supply, machining, welding, preparation, finishing, inspection and delivery responsibilities. ACS confirms the agreed scope and sequence before accepting the work.

Materials and field-work requirements

Supply the exact material specification, including carbon steel or 304/316 stainless where specified. Specialty alloys, including duplex or aluminum inquiries, require review of the drawing and fabrication scope before acceptance.

Installed equipment and field rubber lining

For equipment that cannot travel to the shop, discuss field rubber lining and repairs. Include location, dimensions, access, existing lining, service conditions and the available shutdown window.

Review rush eligibility and shipping

Common questions

Can fabrication and finishing be quoted together?

Yes. Include the drawing, material, fabrication scope, coating or finishing specification and inspection requirements. ACS reviews the sequence and scope before confirming the quotation.

What information is required for an ASME B31.3 pipe spool inquiry?

Provide drawings, material specifications, applicable code and specification revisions, dimensions, quantity, required testing and documentation, and the coating or lining requirements. The project requirements determine the agreed fabrication scope.
