SNT 3.05.01-2016 — Gas supply systems. Rules for performance and acceptance of works. This national technical document establishes requirements and procedures for the execution, inspection and acceptance (handover) of construction, installation, testing and commissioning activities related to gas supply systems in the Turkmenistan national SNT series.

Abstract

This standard sets out technical and procedural rules for carrying out work on gas distribution and service systems, and for formal acceptance of completed works. It covers workmanship, testing (including pressure and leak tests), quality control, documentation required for handover, and criteria used by inspectors to accept or reject completed elements of gas supply projects. The document is published as SNT 3.05.01-2016 and is listed in collections of Turkmenistan SNT construction norms.

Scope

The scope covers performance and acceptance rules for gas supply works within Turkmenistan’s national construction practice. It applies to on-site construction and installation activities for gas mains, service lines, meter installations, internal building gas connections (where specified), associated civil works and associated testing and documentation required for final handover and commissioning. The standard is intended to be used where national SNT rules are applicable to gas distribution projects.

Key topics and requirements

• Definitions and terminology for gas supply works (as used in the SNT series).
• Requirements for materials, components and workmanship used in gas mains and service lines.
• Procedures for site preparation, excavation, laying of pipelines and backfilling.
• Joining methods (welding, mechanical joints, fusion), inspection and acceptance criteria.
• Pressure testing and leak testing procedures, test pressures and hold times.
• Corrosion protection, insulation and bedding requirements for buried pipelines.
• Inspection, quality control and records required for intermediate and final acceptance.
• Documentation, as-built records and certificates required for commissioning and handover.
• Safety, temporary protections and requirements for working near existing utilities.

Typical use and users

Primary users are gas network operators, contracting and installation companies, construction supervisors, site inspectors and acceptance commissions, consulting engineers and authorities responsible for approval and commissioning of gas infrastructure projects in Turkmenistan. The standard is used during project execution, for quality control on site, and as the basis for formal acceptance (handover) of completed gas works.
