Automotive brake hard tube OE No. 95B121447E pressure resistance and stable air tightness
Automotive brake hard pipe is also known as double-layer brazed steel pipe or Bundy pipe; double-wall structure to enhance pressure resistance; copper plating treatment on inner and outer wall surfaces, with a plating thickness of more than 3um, to strengthen the corrosion resistance; high-quality welding process, with no welding beads and discoloration of welded portions; high pressure resistance of up to 1,200kg/cm2; vibration resistance, pressure resistance, and stable air-tightness; capable of a variety of bending and end processing; can be coated with Galvanized and fluorine resin coating treatment; NSG and PA12 coating treatment on the surface is possible.

Structure of Rigid Tube Endoscopes To use a rigid tube endoscope correctly, you should understand its structure. At present, although the products of various rigid tube endoscopes production factories in the world have different optical paths and different appearances, their basic structures are the same: they are composed of a working mirror tube part, a structural part, an eyecup part, and a fiber-optic cable interface part. The main part of the structure, the eyecup part, and the fiber optic cable interface part are generally not easy to be damaged except by violent knocks. The part that is easily damaged is the working tube part. Take φ4mm rigid tube endoscope as an example: the working mirror tube is mainly composed of four parts: outer mirror tube, inner mirror tube, optical lens and optical fiber. The optical lens is placed in the inner lens tube to form the optical system, and the optical fiber is placed between the inner and outer lens tubes for illumination. The outer mirror tube is a 0.1mm thick φ4mm stainless steel tube, which will be deformed if it is bumped or squeezed. Most of the optical lens is a glass column of φ2.8mm with a length of 25mm or so, and it will be cracked, chipped or the optical axis will be shifted when it is slightly bumped and squeezed, and the blurred vision and blackened edge of the endoscopic view that we commonly see is mostly due to this kind of reason. The optical fiber is made of very fine optical glass, a φ4mm speculum should be loaded with more than 1,500 roots, and the external force in the endoscope tube will cause the broken wire and affect the illumination. Rigid tube endoscopes are mostly connected with epoxy resin glue, the quality of the glue and encapsulation technology also affects the service life of the speculum. Although the rigid tube endoscope is delicate, as long as it can be used and maintained correctly, it will not be damaged.

Installing a fresh air system often requires the installation of ducts to exhaust or supply air. In the house is more confined and easy to nest wind place, there are pipes of the new air system has no pipeline negative pressure or pressurized new air system incomparable advantages, can be in the local place to form the air convection, so as to achieve a more ideal ventilation and air exchange effect. Therefore, whether it is a total heat exchange air system, self-balancing air system or unidirectional flow of new air ventilation system try to use the pipeline to ventilate the room.
