What is the difference between a new type of tube carat tube and a PE double wall bellows? Today, follow the craftsman equipment manufacturer to find out:
Difference between carat tube and PE double wall bellows
This paper mainly analyzes the difference between HDPE high density polyethylene winding reinforced pipe and HDPE high density polyethylene double wall bellows.
Carat tube (HDPE wound B tube)
Product Name: carat tube
Adopt the standard: the tube of carat tube must conform to the GB/T19472.2-2004 type B structure wall tube.
Connection mode: the clam pipe adopts the wound socket type electric melting connection pipe winding material.
Major raw materials: non-toxic and harmless high-density polyethylene (PE), polypropylene (PP) bellows as the top-grade skeleton tube, mixed with certain colorimetric masterbatch for a scientific and uniform proportion.
The HDPE high density polyethylene double wall bellows is referred to as:
Product Name: PE double wall bellows
Adopt standard: PE double wall bellows pipe must conform to GB/T19472.1-2004 type B structure wall pipe.
Connection mode: PE double wall bellows connection mode is tight type socket type filler connection.
Main raw materials: high density polyethylene or rigid polyvinyl chloride resin as the main raw material.
1. Carat tube (HDPE wound B tube)

1, what is the carat tube?
Clay tube (HDPE winding reinforced tube) is a kind of high density polyethylene structure wall hot-wound tube, HDPE winding structure wall tube, it is a new type of special-shaped structure wall tube, made of high density polyethylene hot-wound molding process.
2, carat tube product specifications:
Clark tube product specifications (mm): DN300, DN400, DN500, DN600, DN700, DN800, DN900, DN1000, DN1100, DN1200, DN1300, DN1400, DN1500, DN1600, DN1700, DN1800, DN1900, DN2000, DN2200, DN2400, DN2500, DN2600, DN2800, DN3000 and other specifications.
3, the production process of carat tube:
High density polyethylene (HDPE) winding reinforced pipe is made of HDPE in hot melt state by winding forming technology. Before demoulding in hot state, the tube is cooled by rolling air cooling method. The pipe gradually dissipates heat and the wall thickness is uniform. HDPE winding reinforcing pipe is connected by plug-in electric fusion. The two ends of the pipe are processed into sockets and sockets during production, and electric fuse is embedded in the socket. When the pipe is connected, the welding can be completed only by connecting the power supply, and the pipe system can achieve zero leakage.
1) Winding: Hot winding process, melted HDPE plain strip and PP-coated circular stiffener winding synchronously on the mold heated to a predetermined temperature.

2) cutting: pipe bearing and inserting ports are processed to standard size.

3) demoulding: the tube is detached from the mold.

4, the main purpose of the carat tube is:
1) sewage system:
All kinds of wall structure and pipe material are wound by hot structure wall. The inspection wells and fittings can be used for advanced shallow drainage system because of their reliable connection performance.
2) drainage system:
Used to discharge liquids and gases into rivers or seas. Hot structure wall winding pipe has the advantages of light weight, safety, reliable connection, corrosion resistance and high ring stiffness, so it has great advantages to use hot structure winding pipe.
3) tanks and containers:
Pipes made of polyethylene or polyacrylic can be used to produce vertical or horizontal tanks with the following advantages.
Suitable for grain storage; acid and alkali resistance; high strength; 100% reliable; complete system; double wall without leakage.
Two, PE double wall bellows
1, what is PE double wall bellows?
PE double-wall corrugated pipe is a new type of light-weight pipe made of polyethylene by extrusion and special molding process. The inner wall is smooth and the outer wall is closed corrugated.

2, PE double wall bellows production line process flow:
Because PE double-wall bellows are mostly of large caliber specifications and have many raw materials for extrusion molding, twin-screw extruders (parallel or conical twin-screw extruders can be used in general manufacturers), the forming process of PE double-wall bellows mainly passes through three technological processes: tube molding, tube cutting and flaring, as follows
1) tube forming process:
Powder after mixing screen - feeding to Extruder - heating plasticizing to Extruder - shunting to extruder head - compressing to double thin-walled tube - blown by compressed air between module and sizing sleeve - forming inside and outside wall - cooling water sequence but finalized - continuous drawing tube stripping
2) tube cutting process:

3. PE double wall bellows product model:
1) S1 type (ring stiffness greater than 4KN/).
2) Type S2 (ring stiffness (> 8KN /) pipe design and selection, generally speaking, no dynamic load or pipe buried depth of about 0.7-5 meters, choose S1; dynamic load or pipe buried depth is too shallow and too deep, choose S2. In case of special circumstances, professional engineers may be required to communicate with each other to ensure the safety and reliability of pipe selection.
