Tube Processing & Customization
Custom processing requirements are reviewed according to the tube material, dimensions, exchanger drawing and applicable manufacturing requirements.
Custom Sizes & Long Length Tubes
Project-specific OD, wall thickness, finished length and straightness are reviewed together with manufacturing, inspection, packing and transportation requirements.
U-Bending
Drawing-based U-bending with specified centerline radius, straight-leg length, wall-thinning and ovality limits, alignment and post-bend requirements.
Heat Treatment & Solution Annealing
Grade-specific heat-treatment requirements are reviewed against the material standard, manufacturing route and forming operations. Treatment records are provided where required.
Finned Tube Manufacturing
Integral low-fin and high-frequency welded fin requirements are reviewed for material combinations, finished geometry, wall or attachment requirements and inspection criteria.
BA / EP Surface Finish
Bright-annealed and electropolished surface options for applicable stainless steel projects, with finish, roughness and cleanliness requirements agreed before processing.
Inspection & Documentation Support
Inspection methods, acceptance criteria, document requirements and witness points are agreed before production.
Testing & Inspection
Dimensional checks, applicable NDE, pressure testing and material verification are planned according to the product standard and agreed inspection requirements.
EN 10204 3.1 / 3.2
Inspection-document requirements are reviewed before production. Certificate type, supporting records and validation arrangements are confirmed as part of the project inspection plan.
Third-Party Inspection
Document reviews, witness inspections and release requirements are coordinated with the agreed inspection organization or purchaser’s representative.
