High-pressure straight pipe is a tubular component designed to withstand high-pressure environments and is widely used in the industrial sector. Here is a detailed introduction:
Definition and Classification
A high-pressure straight pipe typically refers to high-quality carbon steel, alloy structural steel, and stainless steel seamless pipes used for manufacturing high-pressure vessels and pipelines. It can be classified into two types based on manufacturing methods: hot-rolled (extruded, expanded) and cold-drawn (rolled). Among them, hot-rolled (extruded, expanded) steel pipes have an outer diameter range of 22-530mm and a wall thickness range of 2.0-70mm; cold-drawn (rolled) steel pipes have an outer diameter range of 10-108mm and a wall thickness range of 2.0-13mm.
Features
High strength: Made from high-quality alloy structural steel such as 42CrMo, with the addition of alloy elements like chromium and molybdenum and through special heat treatment processes, it has high tensile strength and yield strength, capable of withstanding high pressure.
Good sealing performance: The end fittings are forged together with the straight pipe, avoiding disassembly. The multiple sealing designs and extremely high processing accuracy ensure the overall pipeline's sealing performance, effectively preventing leakage.
Easy to install and remove: Some high-pressure straight pipes use Acme thread connections, which are convenient and quick to remove, and the connection is firm and reliable, meeting the requirements for rapid installation and removal on-site.
Stable quality: The production process implements full-process quality monitoring, and strict quality control ensures that the product has good comprehensive mechanical properties at room temperature and high temperature, suitable for various working conditions under high-pressure conditions.
