Classification of pipe pilesPipe piles are divided into post-tensioned pre-stressed pipe piles and pre-tensioned pre-stressed pipe piles, pre-stressed concrete pipe piles (PC pipe piles), and pre-stressed concrete thin-walled pipe piles (PTC pipe piles), and high-strength pre-stressed concrete pipes

The high-frequency welding process of submerged arc steel pipe1. Control of the weld gap:After rolling by multiple rollers, the strip steel is sent to the welded pipe unit. The strip steel is gradually rolled up to form a round tube blank with a tooth gap. Adjust the pressing amount of the squeeze r

Anti-corrosion measures for long-distance natural gas pipelinesIn the actual pipeline transportation process, in essence, pipeline corrosion is a normal phenomenon and cannot be completely avoided. To reduce the impact of pipeline corrosion on natural gas transportation, it can only be mitigated by

What is the code for corrosion resistance of 316L stainless steel pipe?1. 316 stainless steel is a kind of stainless steel containing molybdenum. Due to the molybdenum in the steel, the overall performance of this steel is better than 310 and 304 stainless steel. Under high-temperature conditions, w
