@@Liaoyang acoustic test tube nationwide delivery Liaoyang acoustic test tube@@
Liaoyang acoustic test tube manufacturer, Liaoyang acoustic test tube spot, Liaoyang acoustic test tube wholesale, Liaoyang acoustic test tube today's latest quotation, Cangzhou Lianye Steel Pipe Co., Ltd. welcomes your inquiries:
Liaoyang acoustic pipe has three key points:
① The raw material is stainless steel strip
② The forming method generally adopts roller continuous forming
③ The welding method adopts argon arc welding or high-frequency welding, so there is a welding seam.
It is these three points that determine the type and level of Liaoyang's acoustic tube unit, as well as the production and product quality of Liaoyang's acoustic tube.
Liaoyang acoustic pipe requires deep penetration, no oxide inclusions, and the heat affected zone as small as possible. Tungsten inert gas shielded argon arc welding has good adaptability, high welding quality, and good penetration performance. Well, its products are widely used in chemical, nuclear, food and other industrial fields. The low welding speed is a shortcoming of argon arc welding. In order to increase the welding speed, foreign research and development methods have been developed. Among them, the welding method has been developed from single-electrode single-electrode acoustic tube to multi-electrode multi-electrode acoustic tube. This welding method has been applied in production.
In the 1990s, Germany first used multiple welding pipes to be arranged in a straight line along the direction of the weld, forming a long heat flow distribution and significantly increasing the welding speed. Generally, three-electrode argon arc welding is used to weld the steel pipe wall thickness r, the welding speed is ~ times higher than that of a single welding pipe, and the welding quality is also improved. The combination of argon arc welding and plasma welding can weld steel pipes with larger wall thickness.
In addition, using hydrogen gas in argon gas and using high-frequency pulse welding power source can also increase the welding speed. Duoliaoyang acoustic pipe argon arc welding is suitable for the welding of austenitic and ferritic Liaoyang acoustic pipes.
The acceptance of Liaoyang acoustic pipe products is a key point
The acceptance of Liaoyang acoustic pipe is an important process for bridge pile foundation inspection, so how to accept the Liaoyang acoustic pipe?
First, we need to check whether the thickness of the pipe matches the depth of the pile foundation. If the pipe wall is thin, it may affect the accuracy of the pile foundation detection. In addition, check whether the outer wall of the Liaoyang acoustic pipe is intact. , and finally check the firmness of the connections. Ensure safety monitoring after placing piles.
Liaoyang acoustic detection tube is a pile foundation detection tube. It is the channel for ultrasonic testing. It must be fixed to the steel cage. It can only be tied to the steel cage by wire. Why can't it be welded to the Liaoyang acoustic tube?
Because the Liaoyang sonic detection pipe is relatively thin, firstly, the welding may penetrate the Liaoyang sonic detection pipe, which may cause leakage when water is injected. Secondly, welding may occur in the pipe body, affecting ultrasonic testing. Effect.
