2.7. The connecting flanges of pipeline fittings and gate valves must have holes for fasteners and mating surfaces, except as otherwise specified by the customer.
2.8. The internal surfaces of the equipment subject to corrosion protection for the period of transportation, storage and installation must be preserved with compositions and methods that do not require disassembly of the equipment for depreservation.
2.9. Apparatuses containing toxic products during operation, as well as tubular heat exchangers that are under the control of state supervision bodies, must be sealed before transportation and, if indicated in the operational documentation, filled with inert gas or air with excess pressure.
3. COMPLETENESS
3.1. The completeness of the equipment must be determined in the terms of reference, design and regulatory and technical documentation for the equipment.
3.2. In general, a set of equipment should include:
1) foundation bolts with embedded parts;
2) cleaned and mothballed assembly units of pipelines, and for pipelines, the wiring of which is carried out along the foundations and structures of buildings and structures, pipes and necessary connecting parts (flanges, fittings, bent elements with a diameter of more than 40 mm, bends, tees, transitions, etc. );
3) means of technological support for specified requirements and (or) indicators of assembly and installation accuracy, including: support and adjustment tools for aligning equipment on foundations (adjusting screws, support shoes, special jacks, wedge pads, etc.); templates for installing foundation bolts on the most critical or repeating (structurally) types of equipment; conductors for assembling repeating (structurally) assembly units (assemblies) of equipment; special removable lifting devices (clamps, traverses, etc.), as well as special equipment for hydraulic and pneumatic testing, etc.;
4) sealing gaskets, sealing composition and sets of compensating gaskets for installation in connectors of components (assembly units) transported separately;
5) slewing and other devices for installing equipment in the design position;
6) welding consumables (electrodes, welding wire and fluxes) for welding pipelines made of stainless steels and special alloys, as well as pipes for control welding;
7) special tools and fixtures required for installation and testing of equipment. When sending a batch of equipment to one facility, in agreement with the customer, these products are included in the set of the first piece of equipment;
8) products for fixing heat and sound insulation and various internal coatings installed on the equipment, if necessary, to perform the specified work during the installation process;
9) flanges (including mating flanges of all types) to equipment, pipeline fittings and gate valves.
3.3. Each piece of equipment should generally be accompanied by documentation that includes:
1) passport or form and installation instructions in accordance with GOST 2.601-68;
2) picking and packing lists;
3) assembly drawing of equipment and its components (when transporting equipment in parts) in accordance with GOST 2.109-73;
4) installation drawing, except for products for which such drawings are not developed, in accordance with GOST 2.109-73;
5) schemes (hydraulic, pneumatic, etc.) according to GOST 2.701-84;
6) working drawings, passports, certificates, etc. for pipelines, materials and parts for their manufacture, necessary for processing documentation on the delivery of pipelines to state supervision bodies.
3.4. When sending a batch of equipment to one object, the accompanying documentation is included, as a rule, in the set of the first piece of equipment.
