As the core product of Jianlong Plastics, Jianlong brand ground source heat pump pipe is positioned as a "green pipeline advocate". With its excellent system advantages and product characteristics, it has become the preferred pipeline solution in the field of building heating and cooling.

On May 26, 2025, Professor Zhang Heng's research team from the School of Bioengineering at Qingdao University of Science and Technology visited Shandong Jianlong Plastic Co., Ltd. to carry out special docking and exchanges around the antibacterial material technology project, using the collaborative power of industry, academia and research to solve technical problems and inject new impetus into industrial upgrading.

The 5th International Engineering Construction Supply Chain Expo recently concluded successfully at the Tianjin National Convention and Exhibition Center. Shandong Jianlong Plastic Co., Ltd. was awarded the honorary title of "Excellent Supplier of International Engineering Procurement Alliance" at this event!

Today, we will analyze in depth why this HDPE siphon drain pipe stands out among many competing products from the two dimensions of performance characteristics and application scope.

As a leading enterprise in the domestic plastic pipe industry, Shandong Jianlong Plastic Co., Ltd. made a stunning appearance at the 2025 China International Hardware Fair with its full range of innovative pipe products.

When selecting pipe materials for construction projects, performance, safety, and affordability are often key considerations. Jianlong brand green, lead-free, high-impact polyvinyl chloride (PVC-M) water supply pipes, with their innovative technology and superior performance, have become the preferred solution for numerous projects, providing stable and reliable support for water supply and drainage systems.

Definition and material: PVC water supply pipe is a water supply pipe made of sanitary grade polyvinyl chloride resin as the main raw material, with a certain amount of stabilizers, lubricants, fillers, color enhancers, etc. added. It is extruded by a plastic extruder and injection molded by an injection molding machine, and produced through processes such as cooling, curing, shaping, inspection, and packaging.

In PE pipe gas transmission systems, installation compliance directly determines the initial safety of the system, while scientific maintenance is the key to ensuring long-term stable operation. Standard processes and technical requirements must be strictly followed. The specific points are as follows:

The key logic behind choosing PVC pipes (primarily the most widely used UPVC pipes) is that the environment does not have particularly stringent requirements (such as low temperature, high pressure, and severe corrosion), and that cost and basic performance must be balanced. PVC pipes are a better choice when the following environmental conditions are met:

The most common PVC pipes are PVC drainage pipes and PVC water supply pipes. Both are made of polyvinyl chloride resin as the main raw material and are produced through an extrusion molding process. From the literal meaning, it is not difficult to understand that one is used for drainage and the other is used for water supply. But what are the specific differences? Here we list them for you.

Whether serving as the "lifeline" of urban water supply, the "nourishing vein" of farmland irrigation, or the "safety line" of gas transmission, pipeline systems are the core infrastructure supporting production and daily life. Polyethylene (PE) pipe, with its core advantages of durability, ease of use, and environmental friendliness, has long been the preferred choice for pipeline projects. From municipal services to livelihoods, from industry to agriculture, it safeguards every pipeline journey with its strength!

Across the vast fields, every crop thrives on water. An efficient and reliable irrigation system is crucial for farmers to achieve their dreams of a bountiful harvest. With the accelerated pace of agricultural modernization, traditional irrigation pipes are increasingly unable to meet the demands of modern agricultural production due to issues such as fragility, high energy consumption, and difficult maintenance. PE pipes (polyethylene pipes), with their many advantages for adapting to agricultural scenarios, have become the new favorite in the agricultural irrigation field. From field installation to daily irrigation, they empower agricultural production in all aspects, ensuring a smoother path to a bountiful harvest.
