Scope of PER

Pressure Equipment Regulations (PER) 2 (1) These regulations shall apply to the

• design, • manufacture, • operation, • repair, • modification, • maintenance,• inspection and testing

of pressure equipment with a design pressure equal to or greater than 50 kPa (0.5 Bar)

11

Key PER Definitions

Pressure equipment • steam generator, • pressure vessel, • piping, • pressure accessory, • safety accessory, • transportable gas container, • fire extinguisher, • an accumulator, • a hot-water geyser and • a hyperbaric chamber

12

Key PER Definitions

Steam GeneratorAny apparatus to convert water continuously into steam at a pressure higher than atmospheric and where the heat is derived from a source other than steam PipingPipes, tubes or flexible pressure hose elements intended for the transport or distribution of any fluid at a pressure of 50 kPa or above when connected together for integration into a system, including heat exchangers consisting of pipes for the purpose of cooling or heating air PipelinePiping or a system of piping designed for the transport of any fluid from an installation that is onshore or offshore, starting from and including the last isolation device located within the confines of the installation, including all the auxiliary equipment designed specifically for that pipeline

13

Key PER Definitions

Pressure AccessoryA device with an operational function having a pressure–bearing housing

Safety AccessoryA device designed to protect pressure equipment against the allowable limit being exceeded

14

PER: General Requirements

3 (1) Any person who manufactures, imports, sells, offers or supplies any pressure equipment described in these Regulations for use in the Republic shall ensure that such equipment complies with these Regulations.

3 (2) Any person who erects or installs any pressure equipment for use in the Republic shall ensure, as far as is reasonably practicable, that it is erected or installed in a safe manner and without risk to health and safety when properly used.

3 (3) All pressure equipment for use in the Republic shall be categorized and submitted to the applicable conformance assessments of SANS 347 in addition to the requirements of the relevant health and safety standard .....

16

Scope: SANS 347

1.1 This standard specifies the criteria for the categorisation and conformity assessment of pressure equipment (metallic and non-metallic) for use by the manufacturer, users, certification bodies and inspection authorities

1.2 This standard is also applicable to the certification, re-certification, modification or repair of pressure equipment (metallic and non-metallic), as defined by the relevant statutory regulations for pressure equipment

17

SANS 347

Categorization / Categories• Fluid Groups:

• Group1 – Dangerous, • Group 2 – Non-dangerous

• Type of equipment • Equipment Hazard Category (SEP/I/II/III/IV)• Conformity Assessment Module

18

SANS 347

1 - Fluid Groups

Fluid Group 1 (Dangerous)Fluids classified as dangerous substances (in accordance with SANS 10228 ...), for example, fluids that are: explosive, extremely flammable, highly flammable, flammable (where the maximum allowable temperature is above flash point), corrosive, toxic, and oxidising in the Council Directive 67/548/EEC. It also includes saturated and superheated steam

Fluid Group 2 (Non-dangerous)Fluids other than those in group 1, including water below it’s boiling point at atmospheric pressure

19

SANS 347

2 - Determine type of equipment

From SANS 347 types of equipment is determined as: Vessels Steam Generators Piping Pressure Accessory Safety accessory

20

SANS 347

3 - Hazard CategoriesThe categorisation will enable the Mechanical Engineer to determine how the statutory regulations will apply to specific items of pressure equipment according to the five Hazard Categories

• Sound engineering practice (category 0/SEP),• Category I,• Category II,• Category III, &• Category IV.

So what now? 4.1.3 – Category I Equipment:

• Comply to Health and Safety standards

4.1.4 – Category II - IV Equipment: • Design has to be approved by a Professionally Registered Engineer

24

SANS 347

4 - Conformity Assessment CriteriaBefore putting pressure equipment classified as either hazard category I, II, II or IV on the market, such equipment shall be subjected to the procedures in the appropriate conformity assessment modules • Modules A to H

25

SANS 347

Conformity Assessment Criteria (cont.)• The modules for products in categories II, Ill and IV require the

involvement of an independent body, either in the approval and monitoring of the manufacturer's quality system, or in direct product inspection.

• Third-party organizations may also carry out the approval of welding procedures and personnel, including non-destructive testing required for pressure equipment assemblies classified as category II, Ill and IV.

26

SANS 347

5 - Final assessment 5.2.2 Final inspection

• inspection to assess visually and by examination of the accompanying documents compliance

5.2.3 Pressure test• hydrostatic pressure test at a pressure equal to the value specified in

the applicable health and safety standard

SANS 347 - Highlights

ImporterImporter to issue declaration of conformity to PER with verification signature by Approved Inspection Authority (AIA) Competency of DesignerFor Cat II, III and IV competent professional engineer to approve. Designer to issue declaration of conformity/affidavit with supporting documentation Approval of Welding and NDEWelding and NDE procedures and personnel are required to be approved for ALL pressure equipment Cat II, III or IV for ALL modules. Verification of Piping DesignerAnnex B requires AIA to check competency and registration of Piping Designer, not the stress and piping calculations. Piping designer to issue declaration of conformity/Affidavit with supporting documentation

28

SANS 10228 – Fluid group 1

“The identification and classification of dangerous goods for transport”

Classification system: Class 1: explosives (with 6 sub divisions); Class 2: gases:

• Division 2.1: flammable gases;• Division 2.2: non-flammable, non-toxic gases;• Division 2.3: toxic gases;

Class 3: flammable liquids; Class 4: flammable solids; substances liable to spontaneous combustion;

substances that, on contact with water, emit flammable gases; Class 5: oxidising substances and organic peroxides; Class 6: toxic and infectious substances; and Class 7: radioactive material.

29

PER - Duties of Manufacturers

“Manufacturer” means any person who has overall control and isresponsible for the construction of the pressure equipment

4. (1) The manufacturer shall have an obligation to ensure that all equipment designed and manufactured for use in the RSA shall be conformity assessed and subjected to the requirements set out in SANS 347.

4. (5) A manufacturer who determines that pressure equipment in use has a latent defect shall advise the chief Inspector in writing forthwith thereof and of measures being taken to correct the defect

Record keeping by the manufacturer is required for a period of 12 years.

30

PER - Duties of Importers and Suppliers

5. (1) Importers and suppliers shall ensure that pressure equipment sold complies with the requirements of these regulations.

5. (2) The importer shall assume the liability of the manufacturer in terms of these regulations.

Records from manufacturer

31

Pressure and Safety Accessories

The interpretation of pressure accessories is that they are not considered piping components and that they are separate pieces of pressure equipment, e.g.

• Valves (manual and automated)• Steam Traps• Strainers• Flow meters• Instrumentation (gauges, etc.)• Pressure Relief Valves• Bursting Disks, etc.

32

Pressure and Safety Accessories

Non-Operational Piping Components are not considered Pressure Accessories, This means that Pipes, Fittings and Flanges are not considered as Pressure

Accessories and that the requirements of SANS 347 are not applicable These components will be purchased with the normal material certificates.

33

Pressure and Safety Accessories

Certificate of Compliance

Every Pressure and Safety Accessory shall be supplied with:

The certification from the manufacturer for the module that the Pressure or Safety Accessory was manufactured to:

A Declaration of Conformity from the Importer that the Pressure or Safety Accessory meets the requirements of PER and SANS 347
