114 Steel Pipe

Welded steel pipes, that is, slotted steel pipes, are formed by bending pipe blanks (steel plates and steel belts) into pipes with required cross-sectional shapes and sizes through various forming methods, and then welding the weld seams through different welding methods. The process of obtaining steel pipes. Compared with seamless steel pipe, welded steel pipe has higher product accuracy, especially wall thickness accuracy, simple main equipment, small floor space, continuous operation in production, flexible production and wide range of unit products. Welded pipes should be divided into three types according to production technology: spiral submerged arc welded pipes; Straight seam double-sided submerged arc welded pipe; Resistance welded pipe.

Straight seam high frequency welded pipe

Straight-seam high-frequency welded pipe is formed by forming hot-rolled coil by forming machine. The skin effect and proximity effect of high frequency current are used to heat and melt the edge of tube blank, and pressure welding is carried out under the action of extrusion roller to realize production.

UOE molding adopts u and o double pressure molding. It is characterized by large capacity and high output. Suitable for mass production of single specification.

Last week, I had the honor to have a long talk with a senior and old purchaser who has been deeply involved in the procurement field for more than 20 years. During the conversation, he gave me a detailed account, which seemed to take me back to the changeable business era in 1998. He recalled that in 1998, when looking for suppliers, there was a completely different set of "rules of conduct". At that time, the competition was who handed out the cigarettes with better grades and who could better push the cups and call each other brothers on the wine table. It seemed that the business achievement depended more on the "soft power" of these human contacts. ​

However, as time goes by, the business environment has already undergone earth-shaking changes. Nowadays, considering whether a supplier is reliable depends on these three solid and hard-hitting data indicators. ​

First of all, the delivery accuracy has become a key factor to measure suppliers. In the current fast-paced business operation, time is money, and every link is closely linked. An excellent supplier must deliver the goods on time, no matter what kind of bad weather it encounters, even if it is a squall, a downpour, or a holiday, and never delay the production progress of customers. This is not only the persistence of commitment, but also a powerful manifestation of corporate reputation. ​
