How to avoid wear of spiral steel pipe?

Update time : 2022-06-15 15:04:53

　　Spiral welded pipe generally refers to the spiral steel pipe with a diameter greater than 1m. Water pressure, bending, flattening and other tests shall be carried out for steel pipes. There are certain requirements for surface quality. Generally, the delivery length is 12M, and it is often required to deliver in fixed length.

　　In the process of loading and unloading, the spiral steel pipe will inevitably be damaged.

　　1. if the customer requires that the spiral steel pipes have no damage such as collision, the protective device can be used between the spiral steel pipes. Rubber, straw rope, fiber cloth, plastic, pipe cap, etc. Can be used for protection devices.

　　2. packaging materials shall comply with relevant regulations. If packaging materials are not required, they shall conform to the intended use to avoid waste and environmental pollution.

　　3. the spiral pipe shall be packed to avoid loosening and damage during normal loading, unloading, transportation and storage.

　　4. if the buyer has special requirements for the packaging materials and methods of spiral steel pipes, it shall be noted in the contract; If not specified, the supplier can choose the packaging material and packaging method.

　　5. the thin-walled spiral steel pipe can be protected by the support inside the pipe or the frame outside the pipe, because the wall is thick and thin. The same support and frame material as spiral steel pipe.

　　6. if there are thread protectors at both ends of spiral steel pipe, thread protectors shall be used for protection. Apply lubricant or rust inhibitor to the threads. For the openings at both ends of the spiral steel pipe, nozzle protectors can be added at both ends as required.

　　7. if spiral steel pipe is installed in the container, soft moisture-proof devices such as textile cloth and straw mat shall be laid in the container. To prevent the spiral steel pipe from scattering in the container, the protective support can be bound or welded outside the spiral steel pipe.

　　Seamless steel pipe actual bearing pressure may be affected by many factors such as the quality of the pipe, processing technology, and use environment Please feel free to contact us if you have any questions Email : pipe@stpipefitting.cn
(SMLS pipe) is a type of pipe produced without welds by deforming the metal as a whole using piercing and rolling techniques. Compared to welded steel pipe, its core advantage stems from the continuity of the material and the uniformity of its structure, providing superior reliability and safety under high pressure, high temperature, and complex stress environments. This makes seamless steel pipe a fundamental and reliable material in the petroleum, chemical, natural gas, and power industries for critical processes and the transportation of hazardous media.

Seamless carbon steel pipe Sch 40

Sep .15.2026

Seamless Carbon Steel Pipe Sch 40 (Schedule 40) is a seamless steel pipe specification that meets the American standard. Its pipe wall thickness is Sch40 (corresponding to the standard wall thickness series), which represents the standard wall thickness under a specific pressure level and is often used in occasions with higher pressure and temperature.

Schedule 80 Carbon Steel Pipe: Thickness, Dimensions & Weight in mm

Sep .10.2026

Schedule 80 Carbon Steel Pipe is made up of carbon steel materials. The carbon steels can vary in composition based on the grades. The strengths and the toughness vary. To have an international and equal identification of the pressure capacities of the pipes, the schedule scale is used. The wall thickness grades of the steel pipe range from Schedule (SCH) 5 to Schedule (SCH) 160. SCH 5 has the lowest pressure resistance, while SCH 160 has the highest.
