Compliance special equipment gas pipe, Hubei gas engineering material

The compliance special equipment gas pipe belongs to the pressure pipeline components, which is an engineering-grade special pipe specially developed for the gas transportation scene. The whole production process strictly follows the relevant specifications of the national special equipment supervision, and is the mainstream compliance selection of Hubei gas engineering materials. This type of pipe is divided into different pressure grades and pipe diameter specifications according to different application scenarios, which can meet the needs of the whole scene from long-distance high-pressure gas transportation to low-pressure entry at the end point. According to the climate and geological characteristics of Hubei, the performance of special projects has been optimized, which can be adapted to different cities in Hubei and gas engineering construction requirements under different construction conditions. Standardized testing nodes are set up in the whole link from raw material procurement, production and manufacturing to finished product delivery to ensure that the performance parameters of each batch of products are in line with the current national and industry standards, and no substandard products enter the market.

The core selling points of this type of gas pipe mainly include four points, all of which are in line with the actual construction needs of Hubei Gas Project:

1. The whole process of compliance and adaptation, to meet the requirements of inspection and acceptance. The production and manufacture of this type of gas pipe strictly follows the current national and industry standards such as "Pressure Pipeline Safety Technical Supervision Regulations - Industrial Pipeline" and "Buried Polyethylene Pipeline System for Gas", and has obtained the qualification for the manufacture of special equipment pressure piping components. Before each batch of products leaves the factory, a number of mandatory tests such as pressure strength, airtightness, corrosion resistance, and stress cracking resistance are completed. Complete product qualification certificates, test reports and other documents can be provided, which are fully adapted to the application and acceptance process of gas projects in Hubei. It can be put into use normally without additional performance verification, reducing the cost of material verification in the early stage of the project.

2. Strong adaptability to the regional environment, reducing the difficulty of construction. In view of the climate characteristics of high temperature and humidity in summer and low temperature freezing damage in winter under the subtropical monsoon climate in Hubei, as well as the geological conditions of hills, dense water networks, and uneven soil pH in some areas, this type of gas pipe has been optimized by special projects on the formula. The anti-aging performance, low temperature brittle cracking resistance, and acid and alkali corrosion resistance are all higher than the basic requirements of the industry. The underground laying can adapt to various soil environments with pH values between 4 and 10. The open-air temporary deployment can withstand the temperature range of -20 ° C to 60 ° C, and will not cause deformation and leakage problems due to conventional temperature changes. The construction process can choose a variety of connection methods such as hot melt connection, electrofusion connection, flange connection, etc., according to the site conditions. The connection process is mature, and the requirements for the construction environment are low, which can effectively shorten the construction period and adapt to the gas projects with different construction periods in Hubei.

3. Stable performance for long-term use, and controllable operation and maintenance costs. Under the premise of compliance laying and normal use, the design service life of this type of gas pipe is not less than 50 years. During daily operation, the resistance to external impact performance is up to standard, and it can withstand conventional soil settlement and small external disturbance. It is not easy to break and leak. The inner wall of the pipe has high smoothness, the flow resistance during the gas transportation process is small, and it is not easy to retain impurities. Long-term use will not cause the problem of transportation efficiency reduction caused by scaling on the inner wall. At the same time, the maintenance process of the pipe is simple, and the conventional inspection can be completed directly using the existing gas pipeline inspection equipment. There is no need to configure special operation and maintenance tools, which can effectively reduce the operation and maintenance cost of the whole life cycle of

4. Safety performance up to standard and reduce operating risks. The flame retardant performance of this type of gas pipe meets the requirements of industry standards. When encountering open flames, it will not burn rapidly and the fire will spread. It has good anti-static performance, which can avoid safety hazards caused by static electricity accumulation during gas transportation. The gas tightness of the pipe meets the standard. After the connection is completed according to the standard process, the gas leakage rate is far lower than the safety threshold allowed by the industry, which can effectively reduce the safety risks such as explosion and poisoning caused by gas leakage, and fully adapt to the high safety requirements of gas transportation scenarios.

The application scenarios of this type of compliance special equipment gas pipe cover all kinds of gas construction needs in Hubei, mainly including: First, the municipal gas main network, branch pipeline network construction, reconstruction and expansion projects, which can meet the long-distance and wide-range gas transportation requirements of different pressure levels; Second, the gas matching access projects of residential quarters, commercial complexes, and industrial parks can be adapted to different scales of gas demand; Third, the outdoor pipe network laying and end point home connection links of rural gas popularization projects can be adapted to the complex construction conditions of rural areas; Fourth, special scenarios such as gas emergency repair and temporary pipeline laying can be quickly deployed and put into use. The suitable population includes the construction units, construction units, and supervision units of various gas projects in Hubei, the gas operating enterprises responsible for the procurement, operation and maintenance of gas facilities, and the responsible subjects of commercial and industrial projects that need to carry out gas supporting construction and transformation.

At present, this type of compliance special equipment gas pipe has passed the relevant type test of national special equipment. All performance parameters meet the requirements of national mandatory standards, and complete qualification documents and test reports can be provided, which fully meets the regulatory requirements of gas engineering materials in Hubei. Up to now, this type of pipe has been put into use in municipal gas engineering, commercial supporting gas engineering, and rural gas popularization projects in many cities in Hubei. It has a stable long-term operation state and no safety accidents caused by product quality problems. It is a reliable selection of materials for gas engineering in Hubei.
