Abstract
The utility model discloses a U-shaped corrugated seamless steel pipe, which comprises a U-shaped steel pipe which is a corrugated pipe. The utility model solves the problem of per heat exchange performance of the current special-purpose seamless steel pipe for heat exchanger, improves the equipment heat exchange effect, reduces steel pipe welded joints number, and greatly improves the safe operation performance of the equipment.
Description
Technical field:
The utility model relates generally to a kind of steel pipe, specifically is a kind of U type ripple seamless steel pipe
Background technique:
Along with the transformation of China's economy to the marketization also integrates with international economy gradually, market heat exchanging organ pipe bundle is more and more higher with the quality requirement of seamless steel pipe.Heat exchanger to existing seamless steel pipe is made reflects that generally its heat-exchange performance is poor; Welded joint is many, has potential safety hazard.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of U type ripple seamless steel pipe to be provided, and its heat-exchange performance is good and obviously reduced the quantity of welded joint.
The utility model is achieved through the following technical solutions:
U type ripple seamless steel pipe is characterized in that: include the U shape steel tube, described U shape steel tube is a bellows.
The utility model has increased the steel pipe inner and outer surface area, makes heat transferring medium can touch the surface of steel pipe more.Comparing general overall coefficient of heat transfer with common light pipe can be enhanced about more than once; Save the heat exchange area of about 30-40%, or under identical heat exchange area, can reclaim the heat more than 60% more.While is owing to straightway steel pipe employing of the present utility model is bellows, the ripple projection is all arranged inside and outside its pipe, can change the mobile direction of fluid effectively and wash away tube wall, prevent the generation of dirt resistance, reach antiscale and self-cleaning purpose, be implemented in and keep higher heat-transfer effect in the whole on-stream time.With the heat transmission equipment that the utility model is made, welded joint is few, makes the safe running performance of equipment obtain improving widely.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
U type ripple seamless steel pipe includes U shape steel tube 1, and U shape steel tube 1 is a bellows.
