Recently, Shandong Wanji Plastics, headquartered in Huantai, Zibo, officially announced the launch of an intelligent management and control center construction project with a total investment of up to 50 million yuan. This investment and construction is not accidental, but an important decision made by the company based on industry development trends and its own strategic layout. As competition in the domestic pipe industry becomes increasingly fierce, problems such as efficiency bottlenecks and

While the domestic market is steadily expanding, Shandong Wanji Plastics has set its sights on a broader international market. Recently, the company has received heavy news. With excellent product quality, advanced production technology and perfect service system, it has successfully won cooperation orders from the two state-owned enterprises of PetroChina and Sinopec. The PE pipe products produced by it will be widely used in the West-East Gas Transmission downstream pipeline project and the tr

In 2018, the policy of "replacing coal with gas" in Beijing Tianjin Hebei region entered the stage of comprehensive promotion. The implementation of this policy not only effectively improved the air quality, but also gave birth to a huge market demand for natural gas pipelines. At the same time, the continuous landing of municipal water supply and drainage pipelines and supporting infrastructure projects for rural revitalization across the country has also ushered in unprecedented development op

In 2017, the domestic pipe industry ushered in an important period of development opportunities. With the acceleration of urbanization and the continuous promotion of the "coal to gas" policy, the market demand for natural gas pipelines ushered in explosive growth. In this context, the reporter learned from the latest operating data released by Shandong Wanji Plastics that the company's core business natural gas pipeline sector continues to maintain a hot trend and has become the core engine of

PE pipe construction covers pipe groove excavation, pipe connection, installation and laying, backfilling protection, pressure test cleaning and other links. Appropriate connection methods shall be selected according to engineering requirements and the construction quality of each link shall be strictly controlled. The following is the specific construction method: 1. pipe trench excavation and preparation excavation requirements: pipe trench excavation should be in a straight line, and the widt

Against the backdrop of increasingly fierce competition in the pipe‑and‑tube industry, product quality and brand reputation have become the core competitive advantages that enable companies to secure their market position. Recently, Shandong Wanjie Plastics has received a series of accolades. The company has successively obtained certification for three core management systems—ISO 9001 for quality management, ISO 14001 for environmental management, and OHSAS 18001 for occupational health and saf

At present, the market has seen low‑cost PE pipes priced even below the cost of the PE resin itself. Pipes manufactured from such materials cannot possibly meet national standards, posing serious risks to consumers and construction projects. One of the more serious aspects are: 1. Oxidation induction time is not up to standard, the direct impact on the project is to shorten the life of the pipe, in a very short period of time the pipe is aging, can not meet the minimum service life requirements

Pressure reduction of polyethylene PE water supply pipeline system to temperature When the polyethylene pipeline system is used continuously at a temperature above 20 ℃, the reduction coefficient higher than the numerical value can be used as long as the smaller reduction is considered feasible according to the analysis of GB/T 18252 for a certain material with large working pressure. The color of municipal drinking water pipes is blue or black, and the black pipes should have co-extruded blue s

The commonly used connection methods of polyethylene composite pipes with steel wire mesh skeleton for coal mines include electric melting connection, flange connection, clamp type quick connector connection, looper flange type quick connector connection and plate type with neck flange type quick connector connection. The following is a detailed introduction to these connection methods: electric melting connection: principle: the composite pipe is inserted into the electric melting pipe fitting,

Water supply and drainage engineering is the most commonly used material is a variety of pipes, and you have these commonly used pipe and what do you know? Different pipes, different role and usage, let us understand together! 1. polyethylene (PE) pipe PE pipe processing does not add heavy metal salt stabilizer, the material is non-toxic, no scaling layer, no bacteria, a good solution to the secondary pollution of urban drinking water. Except for a few strong oxidants, it can resist the erosion

Temperature and pressure reduction When the polyethylene piping system is continuously operated at a temperature above 20°C, its maximum working pressure needs to be reduced accordingly. For a specific material, if it is feasible to use a smaller reduction factor according to the analysis of GB/T 18252, a higher reduction factor can be used. Pipe color and identification The color of municipal drinking water pipes is specified as blue or black. In the case of black pipe, there shall be a co-extr
