Professional analysis of the three core connection technologies of PE pipes - hot melt docking (large diameter), hot melt socket (small diameter), electrofusion connection (electrofusion pipe fittings) and flange connect

PE pipe as a commonly used pipe material, its connection is very important. Chinese PE pipe manufacturers in the long-term production and practice, the formation of a variety of mature connection methods, Hubei AD Building Materials Co., Ltd. as a professional PE pipe manufacturers, to provide users with reliable connection solutions.

1, hot melt connection: can be divided into hot melt butt and hot melt socket. Hot melt butt is suitable for large diameter PE pipe, through the hot melt butt machine to heat the ends of the pipe to the molten state, and then quickly butt, so that the two closely combined, this way of high strength, good sealing. The hot melt socket is suitable for small diameter PE pipe, using the hot melt characteristics of the socket and the pipe, the pipe is inserted into the socket to achieve a firm connection, which is easy to operate and efficient.

2, Electrofusion connection: It is completed by means of electrofusion pipe fittings. There are heating elements inside the electrofusion pipe fittings. After inserting the PE pipe into the electrofusion pipe fittings, the contact surface between the pipe fittings and the pipe is melted and formed after cooling. Electrofusion connection is easy to operate, especially suitable for on-site construction, which can ensure the reliability of the connection.

3, flange connection: When the PE pipe needs to be connected with pipes or equipment of other materials, flange connection is a good choice. Through flanges, bolts and other accessories, the PE pipe is fixedly connected with other parts, which is firmly connected in this way, easy to disassemble and maintain, and is suitable for a variety of complex engineering scenarios.

PE pipe is a high-performance pipe made of polyethylene (HDPE). As a professional PE pipe manufacturer and Chinese manufacturer, Hubei AD Building Materials Co., Ltd. uses new materials to produce, which has the advantag

PE pipe, that is, polyethylene pipe, is made of polyethylene material. Polyethylene is a thermoplastic resin formed by polymerization of ethylene. It is widely used in many fields due to its good chemical stability, heat resistance, corrosion resistance and anti-aging properties.

According to the difference in density and structure, polyethylene can be divided into low density polyethylene (LDPE), medium density polyethylene (MDPE) and high density polyethylene (HDPE). HDPE is mostly used in the manufacture of PE pipes, which has high mechanical strength and strong chemical corrosion resistance. It is suitable for water pipes, gas pipes and other fields. Hubei Au Yuan Building Materials Co., Ltd., as a professional PE pipe manufacturer, manufacturer and supplier, always insists on using new PE pipe materials for production to ensure product performance and quality from the source. The PE pipe made of new material has excellent hygiene, does not scale, does not breed bacteria, and effectively avoids secondary pollution of water quality.

Hubei AD Building Materials Co., Ltd. has advanced production equipment and mature technology, which can produce a variety of specifications and types of PE pipes to meet the needs of different industries such as construction, municipal administration, energy, and environmental protection. During the production process, the company strictly controls the quality. The products have won high recognition in the market for their reliable quality and have been successfully applied to many large-scale engineering projects. Choosing the PE pipe products of Hubei AD Building Materials Co., Ltd. is to put a "peace of mind lock" on the safe and stable operation of the pipeline system.

Professional pipeline procurement customization services, covering product list inquiry, production customization, logistics delivery and after-sales services. From demand submission to after-sales maintenance, the whole

Pipeline procurement customization process

1. Product list inquiry

Demand submission: Customers need to submit a detailed pipeline procurement customization product list to our business POC. The list must cover the specifications and models of the pipeline (such as pipe diameter, wall thickness, length), material requirements (such as ppr, pvc, mpp, pphm, PE), technical parameters (pressure level, temperature resistance range), purchase quantity and special customization requirements (such as special interface, length processing). At the same time, clarify the expected delivery time and delivery location. Quotation and delivery feedback: After our business team receives the product list, it will organize technology, production, procurement and other departments to evaluate within 1 working day. Combined with market conditions, production costs, customization difficulty and other factors, give accurate quotations, and clarify the unit price, total price and payment method of each product.
