Extruded finned tube supplier from China- Glorytubetech

Extruded finned tube

Extruded finned tubes are mostly bimetallic composite finned tubes, which are in the form of base tube sleeved aluminum tubes. (The base tube can be made of carbon steel, stainless steel, copper，or Titanium) through the machine, extrusion to form fins. And the base of the fin and the tube The outer wall fits closely, So the heat transfer coefficient is high, and the heat transfer performance is excellent.
The extruded fin tube also can be made of pure aluminum or pure copper. And the aluminum-rolled fin tube is integrally rolled from an aluminum tube. As it has no contact thermal resistance, high strength, thermal shock resistance, mechanical vibration, and thermal expansion performance. And has a considerable expansion of the heat exchange surface, the heat exchanger made of this finned tube is ahead of the string or wound fin heat exchanger.

Principle of rail clamp design

Principle of rail clamp design rail clamp design The rail clamp design has several functional features: 1. Adjustability: The adjustable length is 15mm, and its adjustability functions include: (1) The rail presser is easy to install, saves time, and has high precision (2) The track can be adjusted if the structure of the support beam is slightly changed. 2. Anti-loosening: Under the action of the lateral force of the track, through the force analysis of the welding RTYB, a part of these lateral forces are transmitted to the bottom seat through the upper cover plate as the pressure of the bottom edge to seat on the upper cover plate. The other part is the lateral friction between the base and the upper cover. Since the wedge-shaped action between the base and the upper cover plate is converted into the tightening force of the bolts, it has an anti-loosening effect. 3. Self-locking: The three pieces are self-locking together through the interaction of the upper cover, the base, and the

What is rail creep

What is rail creep rail creep Rail creep is also known as line crawl. The creeping phenomenon of the rail along the longitudinal direction of the line. With the increase in railway transportation tasks, the impact of the wheels on the rails when the train is running accelerates the creep of the rails. Rail creep can cause many diseases of the line. In order to prevent the occurrence of track creep diseases, it is necessary to find out the real cause of creeping in order to effectively eliminate the problem. There are two different manifestations: the rails move along the soft sleeper surface due to insufficient fastening pressure of the fasteners; the longitudinal movement of the row is caused by insufficient ballast bed resistance. The reason for this is the longitudinal force of the rail caused by the wheel rolling and longitudinal slip, train braking, the change of rail temperature, and the creep caused by the deflection and deformation of the rail under the action of the wheel load
