Engineering Certificate 2Pipeline Welding Quality and Installation Process Requirements
1. Pipes should be installed before blowing root by root to ensure that the pipe is clean;
b. Pipeline welding work by the Labor Bureau to assess the recognition of welders;
c. Pipe weld according to the "hot water boiler safety and technical supervision regulations," the requirements of the inspection;
d. Steel pipe welding should be welded according to the center line of the pipe half welded to prevent the heat concentration and additional stresses, do not allow the weldment in the non-welded surfaces of each layer. The non-welding surface of the lead bluff after each layer of welding, the application of steel brush, planer hammer will be welded slag, flux skin removal, and appearance check, found defects, must be shoveled out of the re-welding, the installation of the certificate of quality of the project.
e. Unqualified welded parts, should be patch welding measures, the same part of the weld the number of times not more than two times.
f. Weld surface quality inspection: the weld surface should be complete, the height shall not be lower than the surface of the base material and smooth transition with the base material, the width of the weld should be beyond the edge of the bevel 2-3 mm.
2. Pipeline installation process
Pipeline installation process should be to maintain vertical and horizontal, the pipeline location, elevation, slope, slope should be in accordance with the requirements of the design drawings, the pipeline should be used for connecting Pipe connection should use counterpart tools, not force counterpart, interface location should avoid the wall and plus casing. When the pipe passes through the wall, it should be equipped with wall casing, and the gap should be filled with asbestos rope.
According to the design requirements and site-specific installation of fixed and adjusted pipeline support hangers, require the correct location, installation of smooth and solid, does not affect the normal thermal expansion of the pipeline.
lifting and handling basic knowledge
construction site lifting and handling is divided into two categories: one is mechanical lifting and handling, the second is manual lifting and handling.
1. commonly used tools
① jack: shall not be overloaded, when used should be placed on a solid and flat foundation, and vertical with the object to be lifted.
② hand chain hoist: check before use whether the components are good; not overloaded; must be hung securely, slowly lifting hoist; should not be in the role of the load for a long time parked, if necessary, will be zipper chained in the heavy chain; drive part should be noted that frequent lubrication.
2. loading and unloading and handling methods
① Rolling method
② Rolling method
Hydrostatic test
① system flushing
In the hydrostatic test, the first clean water rinse the system, certified that the "Quality Certificate of Installation Engineering". System water flushing program should be the system to unlist the flushing pass before re-access to the system, so as not to cause the system debris blockage.
② hydraulic test
When filling the pipe, the pipe should be opened to the high exhaust valve, to be filled with water, close the exhaust valve and water inlet valve;
Pressurization with a test pump, the pressure should be gradually increased, pressurized to a certain value, you should stop and check the pipeline, no problem to continue to pressurize, generally should be divided into 2 ~ 3 times so that the pressure rises to test pressure;
When the pressure reaches the test pressure;
When the pressure reaches the test pressure, the pressure should be increased to the test pressure. >
When the pressure reaches the test pressure (test pressure for strength test pressure is 1.5 times the working pressure), stop pressurization, observation for 10 minutes to the pipeline, accessories and interfaces are not leakage phenomenon, can be considered as strength test qualified;
Hydraulic test is completed after the water is excluded.
The results of the hydrostatic test will be recorded in the "industrial boiler installation project quality certificate", and have to participate in the acceptance of personnel signatures, and finally archived.
Anti-corrosion and heat preservation
1. Rust removal and anti-corrosion
Including a variety of pipelines, pipe fittings, valves and their concave part of the surface of the metal equipment, artificial descaling; a variety of pipelines, pipe fittings, valves and their concave part of the surface of the metal equipment, the brush to reduce the rust paint.
2. Pipe coloring
Pipe name color Pipe name color
Base color ring base color ring
Saturated steam pipe red-condensate pipe green red
Exhaust steam pipe red-black softened water pipe green-white
Boiler discharge pipe black-feed pipe green-yellow
Boiler feed pipe green-yellow
Pipes and valves, and their convex parts. p>
Boiler feed pipe green - hot water supply pipe red red
Drainage pipe green black hot water return pipe red blue
3. Pipeline and heat storage tank insulation
Pipeline insulation using rubber insulation pipe wrapped in white tape.
Thermal storage tank with a thickness of 100mm rubber insulation board insulation, side package of a folded layer of color steel plate, as the insulation layer of moisture, vapor barrier protection layer, the top of the white tin roof.
Outdoor water tanks should also consider waterproofing, conditions are best made into a vault. Electrical engineering project construction method" for="pagetitle">
Electrical engineering project construction method

Antirust paint, equipment installation in place immediately after the secondary line connection.
① electronic control cabinet installation
Electronic control cabinets in the transportation and installation should be shock-proof, moisture-proof, to prevent deformation of the framework of the paint damage, and in the unpacking of specifications carefully check the model, collect all the information. Installation of electronic control cabinets to find the right, leveling, and the foundation of the steel coupling fastened.
Electronic control cabinet secondary circuit should be constructed according to the map to meet the design requirements, and in line with GB50171-92 standards.
The cable core and the end of the wire with the end of the circuit number with a cross-section consistent with the plastic tube hot printing, numbering is correct, clear handwriting.
Wiring neat, clear, beautiful, good insulation without damage to the wire.
Floor-to-ceiling distribution box should be made base, into the pool to take waterproof measures.
② cable installation
cable in the transportation loading and unloading process should not make the cable and cable tray damage, rolling must follow the direction of the arrows on the cable tray to indicate rolling.
Cables and accessories to the scene should be complete technical documents, cable type, specifications, length should be in line with the order and design requirements.
Cables are arranged neatly and beautifully, and the bending radius of cables, the spacing of cable support fixing points, the separate configurations of power cables and weak power cables, and the distances between cables and thermal equipment pipelines are all in line with the provisions of the Code.
Power cables, cores should have obvious corresponding labeling, good insulation.
Cable protection tube installation and cable laying should be in line with GB50168-92 standards.
③ steel pipe laying
Galvanized steel pipe wall thickness uniformity, weld uniformity, no splitting, trachoma, thorns and concave flat phenomenon and the steel pipe should be the product material list and certificate of conformity, dark pipe laying should be sealed, into the floor-standing distribution box of the line pipe, should be arranged in a neat manner, the pipe should be listed in the base surface of the surface of the not less than 50mm, the dark pipeline burial Bending radius should not be less than 10 times the outer diameter of the pipe.
