What does B refer to in structural winding wall B-shaped pipe?

In the field of plastic pipes, structural winding wall B-shaped pipes are widely used pipe types, but many people are not clear about the meaning of "B" in their names. The definition of B in structural winding wall B-shaped pipes is closely related to the classification system of international standards.

According to ISO standards, plastic structural wall pipes are divided into A and B types according to the morphological characteristics of the outer wall. Among them, the outer wall of the A-shaped pipe is a smooth structure, and it is further subdivided according to the processing method, including the axial hollow wall pipe and the radial hollow wall pipe; while the outer wall of the B-shaped pipe is a non-smooth structure. According to different processing technologies, the B-shaped pipe can be divided into reinforced pipe, carat pipe (that is, HDPE wound structural wall B-shaped pipe), double-wall corrugated pipe and other types. In simple terms, the "B" in the structural wound wall B-shaped pipe represents the special non-smooth structural design of the pipe outer wall.

Compared with the structural wall A-shaped wound pipe, the non-smooth structure of the B-shaped pipe gives its unique advantages. Taking the carat pipe as an example, as a typical representative of the B-shaped pipe of the structural wall winding pipe, it adopts the hot winding molding process, and the molten HDPE flat strip and the circular reinforcement rib coated with PP are synchronously wound on the steel mold heated to a predetermined temperature to form a spiral structure outer wall with reinforcement ribs. This design greatly improves the ring stiffness of the pipe, enabling it to withstand greater external pressure and perform well in projects with poor foundation conditions or large buried depths. The smooth outer wall of the A-shaped pipe has relatively weak compression resistance under the same conditions. In addition, the non-smooth structure of the B-shaped pipe can also increase the friction between the pipe and the soil, improve the stability of the pipe underground, and reduce the risk of displacement.

among many structural wall B-shaped winding pipe manufacturers, Hubei AD Building Materials Co., Ltd. stands out with excellent product quality and advanced production technology. As a Wuhan carat pipe manufacturer and Hubei carat pipe manufacturer, the company produces AD PE carat pipes that strictly follow industry standards, and are strictly controlled from raw material selection to production process. The structural wall winding pipe B-shaped pipe carat pipe it produces not only has excellent pressure resistance and corrosion resistance, but also can customize specifications according to different engineering needs, providing reliable pipeline solutions for municipal drainage, power communication and other fields.
