Comparison: ASME B31.1 to ASME B31.3 B31 Piping Codes PIPELINE CODES B31.4 Liquid Transportation Pipelines B31.8 Gas Transportation Pipelines B31.11 Slurry. Definitions.(1) In these regulations unless the context otherwise requires,- (a) . Application. Definitions, design, materials and equipment, welding, fabrication, installation, testing, operation and maintenance and corrosion control of CGD network shall be in accordance with requirements of ASME B3.
![]() Scope.(a) These regulations cover the design, materials, fabrication, installation, inspection and testing, commissioning, operation, maintenance, modifications and abandonment of CGD network for domestic, commercial and industrial users.(b) Requirements of these regulations shall apply to all pipelines, distribution mains and piping facilities downstream of inlet isolation valve of city gate station (CGS) up to and including consumer meter for commercial or industrial customer and up to final isolation valve including connecting hose to gas appliance for domestic consumer.(c) Design, materials, fabrication, installation, inspection and testing, commissioning, operation, maintenance, modifications and abandonment of steel pipeline between city gate station and natural gas pipeline (sub transmission pipeline) shall be as per separate regulations.(d) The CNG Station, CNG Mother Station, CNG On- Line Station and CNG Daughter Station shall be designed, operated and maintained in line with the requirements of the Chief Controller of Explosives as detailed in the Gas Cylinder Rules, 2. This includes compression, handling and transportation activities of compressed natural gas.(e) These regulations also cover safety aspects of operation and maintenance of CGD network and the requirements covered herein these regulations are meant to supplement the safety requirements already covered under ASME B 3. Intent.(a) It is intended to apply these regulations to all new and such aspects of already existing networks as design, fabrication, installation, testing at the time of construction and commissioning. However, if an entity has laid, built, constructed or expanded the CGD infrastructure based on some other standard or is not meeting the standards specified in these regulations, the entity needs to carry out a detailed technical audit of its infrastructure through a Board authorized or approved third party agency by the Board. The entity thereafter shall submit the recommendations made by the third party along- with its time- based mitigation plan and implementation schedule to the Board for authorization within six months from the date of notification of these regulations.(b) The continuation of operation of existing CGD network shall be allowed only if it meets the following requirements, namely: -(i) The CGD system downstream of city gate station shall have been tested initially at the time of commissioning in accordance with ASME B 3. Chapter IV (with minimum test pressure of 1. MAOP for steel network and 1. MAOP or 5. 0 PSI whichever is higher for PE network). The entity should have proper records of the same. Such test record shall have been valid for the current operation. Alternatively, if such a record is not available, the entity should produce in service test record of the CGD network having tested at a pressure of 1. MAOP as per ASME B 3. The CGD system has leak detection system in position and is operative. For pipeline network it shall be odorisation based and for enclosures such as CGS, above ground DPRS, it shall be gas leak detection based.(iii) The CGD system has in position necessary pressure relief valves; and(iv) There shall be protection of the system against third party damages both in respect to steel pipe, PE pipe and copper tubing. Provided that- (a) The entity shall submit self- certification in support of meeting the above requirements within a month of notification of these regulations and in addition the certification by the approved or authorised third party shall be made available to the Board within six months of notification; (b) Certifications referred to in para (a) shall be done both for operation and maintenance and infrastructure of the entity and shall be submitted to the Board with mitigation plan and implementation schedule; (c) The critical components of the system as identified by the Board for such existing networks shall be complied with these regulations within a period specified at Appendix- I and the authorized entity shall maintain the integrity of the existing system at all times; and(d) Provisions of these regulations related to operation and maintenance procedures shall also be applicable to all such existing installations. The standard. Technical standards and specifications including safety standards (hereinafter referred to as standards) for city or local natural gas distribution networks are as specified in Schedule- I which cover material and equipment (Schedule- 1. A), welding (Schedule- 1. B), piping system components and fabrication (Schedule- 1. C), design, installation and testing (Schedule- 1. D), operating and maintenance procedures (Schedule- 1. E), corrosion control (Schedule- 1. F) and miscellaneous (Schedule- 1. G). 7. Default and consequences.(1) There shall be a system for ensuring compliance to the provision of these regulations through conduct of technical and safety audits during the construction, commissioning and operation phase, as well as on an on- going basis as may be specified from time to time.(2) The Board shall monitor the compliance to Technical Standards and Specifications including Safety Standards either directly or by accredited third party through separate regulations on third party conformity assessment.(3) In case of any deviation or shortfall, in achieving the targets for implementing the specified standards, the entities shall be liable to face the following consequences, namely: -(i) in case of critical activities at Appendix- I, the entity shall be given a single notice by the Board specifying the time limit to remove the specified shortcoming and ensure compliance and if the entity fails to comply within the specified time limit, immediate suspension or termination, as deemed appropriate, of authorization shall be done; (ii) in other cases, the Board may issue a notice to defaulting entity allowing it a reasonable time to remove the specified short coming and ensure compliance and in case the entity fails to comply within the specified time or in case the entity defaults on more than three occasions, its authorization to lay, built, operate or expand the CGD network shall be liable for suspension or termination apart from taking legal action under the provision of the Act and regulations thereunder. Requirements under other statutes. It shall be necessary to comply with all statutory rules, regulations and Acts in force as applicable and requisite approvals shall be obtained from the relevant competent authorities for the CGD network. Miscellaneous.(1) These standards are intended to ensure uniform application of design principles and to guide selection and application of materials and components. Though the standard primarily focuses on safety of employees, public and facilities associated with city or local natural gas distribution networks, it does not eliminate the need for a competent designer and good engineering judgment. If any question arises as to the interpretation of these regulations, the same shall be decided by the Board. APPENDIX- ILIST OF CRITICAL ACTIVITIES In CGD NETWORK.
