Specification
The spiral pipe welding process is also the difference between SSAW and LSAW, which is the form of welding seam. The difference between SAW and ERW is the difference of welding process. According to the production method, steel pipe can be divided into two categories: seamless steel pipe and welded steel pipe. According to the production method, seamless steel pipe can be divided into: hot rolled seamless pipe, cold drawn pipe, precision steel pipe, hot expansion pipe, cold spinning pipe and extrusion pipe. Seamless steel tubes are made of high quality carbon steel or alloy steel.Commonly used standards of the spiral steel pipe can be divided into: SY/T5037-2008 (solid, also known as the common fluid conveying pipe with spiral seam submerged arc welding steel pipe), GB/T9711.1-2008 (national standard, also known as oil and gas industry conveying pipe delivery technical conditions in the first part: grade A steel pipe (GB/T9711.2 strict grade B steel pipe)), API 5 l (American petroleum institute, also known as the pipeline steel pipe; Two grades: PSL1 and PSL2), SY/ t5040-2008 (spiral welded steel pipe for pile)
Large diameter welded pipe is mostly spiral welding.
The commonly used helical pipe materials for structural reinforcement are as follows: Q235A, Q235B, Q345, L245, L290, X42, X52, X60, X70, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb.
The reinforced spiral pipe used for structure is mainly used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction. Liquid transport: water supply, drainage, sewage treatment engineering, mud transport, Marine water transport. For gas transmission: gas, steam, LPG. For structure: piling pipe and bridge; Wharf, road, building structure pipe, Marine piling pipe, etc
- Q:What is the lifespan of steel pipes?
- The lifespan of steel pipes can vary depending on various factors such as the quality of the steel, usage conditions, maintenance, and external factors like corrosion. However, properly installed and maintained steel pipes can typically last for several decades or even a century.
- Q:Can steel pipes be used for transporting drinking water?
- Indeed, steel pipes have the capacity to transport drinking water. These pipes are extensively employed in water distribution networks and have a long history of usage. Renowned for their robustness, potency, and ability to resist corrosion, steel pipes are highly favored. Nonetheless, it is imperative to ensure that steel pipes designated for drinking water transportation are adequately coated or lined in order to avert any potential contamination originating from the metal. Moreover, it is crucial to conduct routine inspections and maintenance to safeguard the pipes' integrity and to forestall any leaks or ruptures that could jeopardize the water's quality.
- Q:Can steel pipes be used for wastewater treatment plants?
- Yes, steel pipes can be used for wastewater treatment plants. Steel pipes are commonly used in these facilities due to their high strength, durability, and resistance to corrosion, making them suitable for handling the harsh and corrosive nature of wastewater. Additionally, steel pipes can be easily welded and are available in various sizes, making them versatile for different applications within wastewater treatment plants.
- Q:What are the different types of gaskets used with steel pipes?
- There are several types of gaskets commonly used with steel pipes, including ring type joint (RTJ) gaskets, spiral wound gaskets, and flat gaskets. RTJ gaskets are designed to create a tight seal by compressing between two flanges, while spiral wound gaskets consist of a metal winding and filler material for enhanced sealing properties. Flat gaskets are typically made from rubber or non-metallic materials and are used for lower pressure applications.
- Q:How much is the tube?
- The first prerequisite we need to determine is: what are the specifications of the steel pipe mentioned? Such as the commonly used steel pipe specifications: diameter 108*4.5, diameter 219*6, diameter 377*10, diameter and wall thickness of steel pipe with different specifications, different weight, so the steel price per meter is different.
- Q:How are steel pipes used in the construction of gas distribution networks?
- Steel pipes are commonly used in the construction of gas distribution networks due to their durability, strength, and ability to withstand high pressure. These pipes are used to transport natural gas from the source to homes, businesses, and industries. The steel pipes are laid underground and connected using fittings and valves to create a network that efficiently distributes gas. It ensures a safe and reliable delivery of gas to consumers while minimizing the risk of leaks or accidents.
- Q:What is the difference between ERW and SAW steel pipes?
- ERW (Electric Resistance Welded) steel pipes are manufactured by welding the edges of the steel strip or coil together to form a pipe. On the other hand, SAW (Submerged Arc Welded) steel pipes are manufactured by welding the steel plates or coils together using a submerged arc welding process. The main difference between the two is the method of welding used. SAW pipes generally have a higher strength and better dimensional accuracy compared to ERW pipes.
- Q:How does the price of steel pipes vary based on market demand?
- The price of steel pipes varies based on market demand because when the demand for steel pipes is high, the prices tend to increase as suppliers can charge more for their products. Conversely, when the demand is low, the prices may decrease as suppliers may need to offer discounts or special deals to attract buyers. Essentially, the price of steel pipes fluctuates with changes in market demand.
- Q:How are steel pipes used in the manufacturing of sewage treatment plants?
- Steel pipes are commonly used in the manufacturing of sewage treatment plants primarily for their durability, strength, and resistance to corrosion. These pipes are utilized for various purposes within the treatment process, including transporting sewage and wastewater between different treatment units, carrying chemicals for disinfection or neutralization, and providing structural support for the plant's infrastructure.
- Q:Can steel pipes be used for underground fuel pipelines?
- Yes, steel pipes can be used for underground fuel pipelines. Steel pipes are commonly used for underground fuel pipelines due to their strength, durability, and resistance to corrosion, making them suitable for transporting fuel safely and efficiently.
