Welded finned tube

 Welded finned tube

We produce laser-welded finned tubes and high-frequency welding finned tubes. And it is widely used for civil wall-hung boilers, industrial boilers, etc. 

There are many types of finned tubes. Although high-frequency welding finned tubes are more advanced in terms of product quality and production automation compared with inlay and brazing methods. Due to its factors such as difficulty in welding the root and wrinkles at the root cause many shortcomings in heat exchange efficiency and fouling prevention. By comparison, the laser-welded finned tube is the most advanced product of irreplaceable advantages. It has a high penetration rate, can prevent crevice corrosion, prolong service life and reduce heat transfer resistance. Breaking through material restrictions. And it can use different materials for processing, saving material costs, and easy for secondary processing.

The disadvantage of laser welding is that the processing time is longer and the output will be limited. Therefore, we still maintain a high-frequency welding production line, which can provide fast and large numbers of finned tubes with low cost, and still has a high market share in general industrial applications.

What are railway rail fasteners？

What are railway rail fasteners？ Railway rail fasteners Railway rail fasteners are a kind of railway accessories. The parts used to combine rails and sleepers (or other types of under-rail foundations) on the track are also called central joint parts. Its function is to fix the steel rail on the sleeper, maintain the gauge and prevent the longitudinal and lateral movement of the rail relative to the sleeper. The railway rail fastener system is divided into the shrapnel fastener system, gusset fastener system, and elastic strip fastener system. The gusset-type fastener is composed of a gusset plate, a threaded spike, a spring washer, an iron seat, and a buffer pad. The threaded spike is anchored in the reserved hole of the concrete sleeper bearing platform with sulfur cement mortar, and then bolts are used to fasten the buckle. Plate fastened. There are elastic strips I, II, and III types of clip fasteners. Type I elastic strip is composed of ω elastic strip,  screw spike , gauge b...
