The quality of the detection of the high-frequency steel pipe is particularly important in the production process due to its high efficiency.

Usually, the high-frequency ultrasonic testing of the steel pipe is divided into two kinds of online and manual ultrasonic flaw detection waves of the line frequency steel pipe installed in a production line online detection of the continuous production of steel pipe, a number of defects will alarm because the online ultrasonic testing equipment is automatic, will appear the phenomenon of underreporting and misstatements in the detection process, each batch of high-frequency steel pipeline even after manual ultrasonic pumping detection.

High-frequency steel pipe using high-frequency welding due to its special production process, welding defects generally appear as fusion, but also because of its current, and voltage controlled by the machine, an amount of high-frequency steel pipe is usually incomplete fusion phenomenon long a high-frequency steel pipe ultrasonic testing to determine more easily. But must require detection to detect fast and slow will affect the efficiency of the production, and also easily lead to an increased amount of steel pipe scrap.

High-frequency steel pipe is generally after the completion of high-frequency welding, using the doctor blade clear the weld, weld almost no more than to reduce the difficulty of the defect judgment, but one should pay attention to the weld location in testing, to avoid judgments error.

Although the ultrasonic flaw detection of the high-frequency steel pipe compared with submerged arc straight-seam pipe is simple, it is the high efficiency of production, the quantity of product defects is also a batch, so the high-frequency flaw detection of the steel tube is particularly important.

Cangzhou Shenlong Pipe Manufacturing Co., Ltd. cooperates with Baosteel and Baogang to produce large-caliber seamless steel pipe, straight-seam welded pipe, spiral steel pipe, and pipe fittings. The products comply with API, ASTM, DIN, BS, and JIS standards, and can accept SGS, BV, and other inspections. The products are used in oil, natural gas, bridge, water conservancy, and other large-scale projects, which are worthy of trust.
