Fourth, the production process of pipe
1. The production process of the pipe The main production process of the pipe is: first wrap a solid wall PE inner layer tube on the host, and then place the steel plate reinforcement folded into an inverted "U" shape on the solid wall PE inner layer tube At the design position, a PE outer layer with the same waveform as the steel belt reinforcement is extruded and compounded on the outside, and the finished pipe can be obtained after shaping, shaping, cooling and cutting.
The main requirements of the production process are: in a short period of time, when the inner layer and the outer layer are in a molten state, under a certain pressure, the inner layer tube, the steel strip reinforcement, and the outer layer PE complete the compound to ensure that each layer is compounded A monolithic tube wall.
The two main processes of coating and extrusion winding for pipe production are as follows:
(1). Steel strip coating process
Steel strip coating process is as follows:
In the steel strip coating process, the focus is on controlling the temperature of the heating and incubator, so that the bonding resin can be well coated on the surface of the steel strip to ensure the bonding strength; another important point is to control the extrusion speed and traction speed of the extruder, Ensure stable coating thickness.
(2). Extrusion winding production process
The process of extrusion winding is as follows:
The extrusion winding process focuses on controlling the inner and outer winding thickness, the speed of the steel belt, and the heating temperature of the steel belt; the composite of the steel belt must ensure the temperature and pressure of the composite process to ensure the stable quality of the pipe.
Fifth, the connection of the pipeline
One of the advantages of plastic pipes is that the system has a particularly high sealing performance when transporting fluids, and the key to its sealing performance is the sealing reliability of the pipe connection parts. The historical experience of pipeline application proves that the key to the success of the promotion and application of the new pipeline is to see whether there is a connection technology that is consistent with the performance and service life of the pipe. The connection method specified in this standard is a typical connection method for practical applications. The connection methods that have been widely used in engineering are: hot melt extrusion welding connection, heat shrinkable tube (belt) connection, clamp (huff sleeve) connection, electric fusion tape connection, socket type electric fusion or sealing ring connection Etc., these connection methods have more mature connection structure and connection product and construction technology, and two (or three) connection methods can be used in combination when needed.

Steel strip steel is easy to rust in air and water, and the corrosion rate of zinc in the atmosphere is only 1/15 of the corrosion rate of steel in the atmosphere. Galvanized steel plate is to protect the steel plate from corrosion by a dense galvanized layer. Steel belt (steel-belt) refers to the conveyor belt made of carbon steel used as the traction and carrying member of the belt conveyor, and can also be used to bundle goods; A narrow and long steel plate produced for the needs of mechanical products. The steel belt is also called steel belt, and its width is within 1300mm, and the length is slightly different according to the size of each roll. Strip steel is generally supplied in coils, which has the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving. Steel strips are divided into ordinary steel strips and high-quality steel strips according to the materials used; there are two types of hot-rolled steel strips and cold-rolled steel strips according to the processing method.
corrugated pipe English name: corrugated pipe. Types of corrugated pipe: corrugated pipe mainly include metal corrugated pipe, corrugated pipe expansion joints, corrugated pipe heat exchange tubes, diaphragm capsules and metal hoses. The metal corrugated pipe is mainly used to compensate the thermal deformation of the pipeline, shock absorption, absorption of settlement deformation of the pipeline, etc. It is widely used in petrochemical, instrumentation, aerospace, chemical, electric power, cement, metallurgy and other industries. Plastic and other corrugated pipes play an irreplaceable role in the fields of media transmission, power threading, machine tools, and home appliances. corrugated pipe: A kind of pressure measuring elastic element in pressure measuring instruments. It is a cylindrical thin-walled wrinkled shell with multiple transverse corrugations. The corrugated pipe have elasticity and can produce displacement under the action of pressure, axial force, lateral force or bending moment. corrugated pipe are widely used in instruments and meters, the main purpose is to be used as a measuring element of pressure measuring instruments to convert pressure into displacement or force. corrugated pipe have thinner walls and higher sensitivity, and the measuring range is from tens of MPa to tens of MPa. In addition, the corrugated pipe can also be used as a sealing isolation element to separate the two media or prevent harmful fluids from entering the measurement part of the device. It can also be used as a compensation element, using its volume variability to compensate for the temperature error of the instrument. It is sometimes used as an elastic joint for two parts. Corrugated pipes can be divided into metal corrugated pipe and non-metallic corrugated pipe according to the constituent materials; they can be divided into single layer and multilayer according to the structure. Single-layer corrugated pipe (see picture) are used in many applications. Multi-layer corrugated pipe have high strength, good durability and low stress, and are used in important measurements. The materials of corrugated pipe are generally bronze, brass, stainless steel, Monel and Inconel.
