Its PE pipe products will be widely used in the downstream West-East Gas Pipeline project and the cross-border gas pipeline project from Kazakhstan to Xinjiang. This marks Wanji Plastics' official breakthrough of overseas market barriers and its entry into the international energy pipeline market.This breakthrough is not only important for businesses...

In 2017, the domestic pipe industry ushered in a significant period of development opportunities. With the acceleration of urbanization across the country and the continued implementation of the 'coal-to-gas' policy, the demand for natural gas pipelines experienced explosive growth. Against this backdrop, according to the latest operating data released by Shandong Wanji Plastics, the company's core natural gas pipeline business continued its booming performance, becoming the core engine of the company's revenue growth. According to the head of the company's production department, to cope with the surge in order demand, the company's 10 natural gas pipeline production lines have been put into operation...Full-load operation mode under all weather conditions...

In 2018, the "gas-for-coal" policy in the Beijing-Tianjin-Hebei region entered a phase of full-scale implementation. This policy not only effectively improved air quality but also spurred huge demand for natural gas pipelines. Simultaneously, the continued implementation of municipal water supply and drainage pipelines and rural revitalization infrastructure projects nationwide has brought unprecedented development opportunities to the pipe materials market. To seize this historic opportunity and meet the growing market demand across the country, Shandong Wanji Plastics officially launched a large-scale capacity expansion plan.Scale of entry, rate of increase in production capacity...

In the increasingly competitive pipe industry, product quality and brand reputation have become the core competitiveness for enterprises to survive in the market. Recently, Shandong Wanji Plastics has received a series of good news: the company has successively passed ISO9001 quality management system certification, ISO14001 environmental management system certification, and OHSAS18001 occupational health and safety management system certification. At the same time, thanks to its high-quality products and comprehensive services, it has won awards such as "China's Famous Brand," "AAA Enterprise for Quality, Service, and Reputation," and "Leading Brand in Jiangbei Pipe Industry"...

PE pipe construction encompasses trench excavation, pipe connection, installation, backfilling and protection, and pressure testing and cleaning. Appropriate connection methods must be selected based on project requirements, and the construction quality of each stage must be strictly controlled. The specific construction methods are as follows: I. Trench Excavation and Preparation Requirements: Trench excavation should ideally be in a straight line. The trench bottom width is typically DN (nominal pipe diameter) + 0.30m. If the pipe needs to be connected underground, the trench bottom width at the joint should be appropriately increased, not less than DN + 0.50m, to facilitate installation and connection. When burying the pipe, the minimum top diameter...Soil...

Currently, cheap PE pipes on the market are priced even lower than the cost of PE raw materials. PE pipes made from these materials simply cannot meet national standards, causing serious damage to users and projects. Some of the more serious issues include: 1. Inadequate oxidation induction time, directly impacting pipe lifespan by causing rapid aging and failing to meet the minimum 50-year service life requirement. 2. Decreased weather resistance. 3. Poor long-term hydrostatic strength and resistance to...

Pressure reduction for polyethylene (PE) water supply pipe systems due to temperature: When a polyethylene pipe system is used continuously at temperatures above 20℃, for a given material at its maximum working pressure, if the analysis according to GB/T 18252 deems a smaller reduction feasible, a higher reduction factor can be used. Municipal drinking water pipes are blue or black, and black pipes should have co-extruded blue stripes. There should be at least three stripes along the longitudinal direction of the pipe. PE water supply pipes are a type of PE pipe; there are many types of PE pipes used in various fields, including PE water supply, PE wiring, etc...

Common connection methods for steel wire mesh reinforced polyethylene composite pipes used in coal mines include electrofusion connection, flange connection, clamp-type quick coupling connection, slip-on flange-type quick coupling connection, and plate-type necked flange-type quick coupling connection. The following is a detailed introduction to these connection methods: Electrofusion Connection: Principle: The composite pipe is inserted into the electrofusion fitting, and an electric heating wire embedded in the inner surface of the fitting is energized to heat it. This first melts the inner surface of the fitting, creating a molten body. The molten body expands and fills the gap between the pipe and fitting until the outer surface of the pipe also produces a molten body.A melt, two melts melting together...

The most commonly used materials in water supply and drainage engineering are various pipes. What do you know about these commonly used pipes? Different pipes have different functions and uses. Let's learn about them together! I. Polyethylene (PE) Pipes PE pipes are processed without the addition of heavy metal salt stabilizers, making the material non-toxic, free of scale, and non-breeding of bacteria, effectively solving the problem of secondary pollution of urban drinking water. Except for a few strong oxidizing agents, they are resistant to the erosion of various chemical media; there is no electrochemical corrosion. Under rated temperature and pressure conditions, PE pipes can...Use 50%...

Temperature and Pressure Reduction: When a polyethylene pipeline system operates continuously at temperatures above 20°C, its maximum working pressure must be reduced accordingly. For a specific material, if the analysis in GB/T 18252 determines that a smaller reduction factor is feasible, then a higher reduction factor can be used. Pipe Color and Marking: The color of municipal drinking water pipes is specified as blue or black. If black pipes are used, they must have co-extruded blue stripes, and there should be at least three stripes along the longitudinal direction of the pipe. This color and marking specification...Helpful in...
