1. All furnace tubes and furnace tubes are installed and inspected.
2. All heating furnace tubes and furnace tubes are systematically purged and cleaned according to the provisions of Chapter 7 of the "Code for the Construction and Acceptance of Industrial Pipework" (GBJ235-82).
3. The installation of steel structures and pipe frames and tube plates related to the pressure test system shall meet the design requirements.
4. Two test pressure gauges shall be installed before the test, and the range is preferably twice the test pressure. One is installed at the outlet of the hand pump and the other is installed at the heating furnace tube system, and uses this table as the basis of test pressure.
5. Test water should use clean water above 5 °C, generally 20 °C -70 °C.
6. During the hydrostatic test, measures should be taken to remove the air from the system.
7. The pressure-relief elements and components of the furnace system shall be provided with special tools and plugs when carrying out a separate hydrostatic test, preferably on a hydrostatic test stand.

The petrolatum Anti-corrosion tape is made of plastic petrolatum ester, filler, paraffin oil, special preservatives, fillers, synthetic fibers and other raw materials. Gapless flexible ribbon roll. The petrolatum anti-corrosion tape can be used together with the petrolatum topcoat, the petrolatum cement and the polymer adhesive tape to form a complete anti-corrosion maintenance system.
The mineral ester anti-corrosion tape has stable properties, no curing, no hardening, no cracking, adapts to thermal expansion and contraction of workpieces with large temperature changes, has excellent plasticity and flexibility, contains volatiles within a safe range, and is harmful to the human body and the environment. No poison. It is suitable for anti-corrosion work of metal pipes and fittings, Flanges and Valves of any regular and irregular shape. It is widely used in gas, oil, water, petrochemical plants, urban construction, ships and other fields. It is also the first choice for anti-corrosion materials for steel pipelines, cast iron pipelines, joints, tees, elbows, refueling and refueling storage tanks, special-shaped prefabricated components (such as flanges, gate valves, tees, etc.), and edge plates of storage tank bases.
Scope of application
1. Pipeline anti-corrosion
From the pipelines inside and outside the factories of large-scale chemical companies, steel companies, and electric power companies, to equipment pipelines in high-rise buildings, and residential pipelines, whether it is overhead, ground, underground pipe gallery, buried or not in water, all pipelines can be used. Because it does not deteriorate even at the lowest temperature, it is suitable for corrosion protection of low temperature piping such as liquefied gas, and corrosion protection of cooling water and cold air piping.
2. Anti-corrosion of flanges, pipe fittings and welds
The petrolatum anti-corrosion system is a suitable anti-corrosion material for piping connections, valves, flanges, bolts, etc. Pipes pre-coated with plastic and bitumen, etc., can also be used for welds connected in the field.
Specifications of petrolatum anti-corrosion belt:
50mm x 10M, 75mm x 10M 100mm x 10M 150mm x 10M 200mm x 10M 300mm x 10M
The thickness and width of the tape can also be customized according to the user's specific design or construction requirements.
