Piping Systems

Ocean Legacy Marine Engineering (OLME) specialises in the Mechanical Installation of Stainless and Carbon Steel Piping Systems, for various industry sectors.

Our piping installations conform to ASME B31.3 (Process Piping Guide) guidelines and prescribed quality standards as mandated by various industry sectors. All pressure systems conform to SANS 347 (Pressure Equipment Regulation) Hazard Categorization and include all legal documentation requirements.

We utilise manual GTAW and GMAW Welding techniques depending on installation specifications and offer fully documented and validated Piping Systems. All welding works are performed by qualified and trained personnel with appropriate industry certification according to approved procedures and specifications.

Carbon Steel Piping Solutions include Low Pressure/Temperature (Medium Weight) and High Pressure/Temperature (Schedule) systems.

Our Mild Steel Piping reticulations are generally utilised to transfer the following liquids:

Medium Weight - Low Pressure/Temperature

  • Municipal Water Distribution
  • Water Treatment Plant Distribution (Carbon/Sand Filtration, etc.)
  • Compressed Air

Schedule – High Pressure/Temperature

  • High Pressure Water Reticulation
  • Water Treatment Plant Distribution (Carbon/Sand Filtration, etc.)
  • Industrial Steam Distribution
  • Oil/Fuel Transfer Piping

Stainless Steel Piping Solutions include Low Pressure/Temperature (Dairy Thin Walled Members) and High Pressure/Temperature (Schedule Members) systems. Solutions include Stainless Steel materials within the Austenitic and Duplex groups.

We are fully conversant with the following Stainless Steel material specifications with existing Welding Procedure Specifications and Qualifications:

 

  • Stainless Steel 304L
  • Stainless Steel 316L
  • Stainless Steel Duplex 2205
  • Stainless Steel Duplex 2507

 

Our Stainless Steel Piping reticulations are generally utilised to transfer the following liquids:

 

Dairy - Thin Walled Members

  • Municipal Water Distribution
  • Water Treatment Plant Distribution (Reverse Osmosis, Carbon/Sand Filtration, etc.)
  • Product Piping (Human Consumption) – Beverage and Dairy Industry

 

Schedule - High Pressure/Temperature

  • High Pressure Water Reticulation
  • Water Treatment Plant Distribution (Reverse Osmosis, Carbon/Sand Filtration, etc.)
  • Pure Steam Distribution

 

We also offer Stainless Steel Hygienic Piping Solutions confirming to Pharmaceutical Standards. Hygienic Piping installations are recommended within the Pharmaceutical Industry and all product transfer installations within the Food and Beverage Industry.

 

Installations are fully documented and validated prior to commissioning and includes the following information as minimum within a Validation/Data Pack:

  • Weld Procedure Qualification Record (PQR)
  • Weld Procedure Specification (WPS)
  • Welder Performance Qualification (WPQ)
  • Quality Control Procedure (QCP)
  • Design and As-Built Isometric Drawings
  • Weld Log Records (Incl. Sample Welds)
  • Gas Bottle Tags/Certificates
  • Non-Destructive Testing Reports (X-Ray)
  • Pickle and Passivation Reports
  • Alcohol (IPA) Pull Through Records
  • Slope Verification Reports
  • Certificate of Conformity/Compliance
  • Material Certificates (Incl. Consumables)
  • Equipment Certificates
  • Endoscopic Testing
  • Pressure Test Reports

As part of our services we also supply OEM Dockweilwer Piping Materials through our accredited partner and distributor NDE Stainless Steel conforming to ASME BPE standards.

 

We utilise the latest Orbital Cutting and Automatic GTAW Welding Equipment to ensure precision, consistency and complete traceability. Our current Orbital Welding equipment is capable of welding piping within the following diameter ranges – Ø12.7mm – Ø101.4mm (Maximum Ø254mm – Available on Special Request)

 

Our services also include an approved internal Pickle and Passivation Procedure fully documented post any Stainless Steel piping reticulation installation.

 

Through our existing partnerships we offer the following ancillary services required for turnkey piping solutions:

  • Piping Material/Componentry Supply
  • Lagging and Cladding
  • Crane and Rigging Services
  • Non-Destructive Testing (Radiographic, Magnetic Particle, Dye-Penetrant etc.)
  • Approved Inspection Authority (AIA) Verifications

Based on our vast experience within the piping sector and our involvement within the Water Treatment Industry we also offer technical advice and support backed by our specialist partners with regards to material selections and current installation failures and recommendations.
