Rubber Hose Reinforcement Layer Sep 30, 2017

Rubber Hose Reinforcement layer

Hose products in the daily industry is one of the most common use of accessories, but the use of the process will also be a variety of problems, especially rubber hose in the high-pressure working conditions, after years of work experience and user feedback to understand why

1, hose reinforcement layer is not rust, but the phenomenon of irregular broken wire. If the hose rupture, stripping the outer layer inspection did not find the reinforcement layer rust, but the reinforcement layer length direction irregular wire, the main reason is the horn by the impact of high-frequency role.

2, due to the role of external force (shrapnel breakdown, extrusion break) or the system overload lead to rubber hose break larger or soon break, you can take bone method: the hose break at the cleavage clean and remove the crack site; Self-made steel "bone" into the cut off the hose (the situation is particularly urgent, can also be used with the outer diameter of the pipe with the same pipe diameter "bone"); with self-made steel clip to the hose and " Catch (when the situation is particularly urgent, available 8 wire instead of homemade steel clip); will be connected to a good hose after cleaning can be used

3, hose rupture, broken near the braided steel rust. If the high-pressure tubing rupture, stripping the outer rubber layer inspection found near the broken weaving, winding steel rust phenomenon, which is mainly due to the outer layer of wet or corrosive substances, weakened the hose strength, resulting in high pressure rupture.

This situation, generally associated with the outer fracture, abrasions or serious deterioration of the phenomenon, so that the outer layer of the strengthening of the protective layer of the role. At this time must first check and eliminate the external rubber layer of mechanical damage, chemical corrosion and high temperature baking and other adverse factors, and then replace the hose. However, there are cases where the outer layer is kept well but the reinforcing layer is embroidered and broken, and the break is usually in the range of 200 mm from the hose joint. The reason is that the hydraulic joint is unacceptable and the moisture enters the inner edge of the jacket, So that the reinforcement layer absorbs moisture, resulting in rust caused by the hose pressure reduction strength and rupture.

Note: hose arrangements to try to prevent heat, away from the engine exhaust pipe. If necessary, can be used casing or maintenance screen and other equipment to prevent the heat of the hose transformation. Hose equipment should be kept in a tight state, even if the hose is not relative to the local movement, but also adhere to the hose lax, tension hose under the pressure effect will swell, strength decreased. Do not misunderstand the hose during the equipment. The hose has been slender to have the ability to reduce its strength and loose joints, oil drilling rubber hose equipment should be tightened in the hose on the hose, rather than tighten the hose on the joint. Hose, such as equipment in the key components, advocate its time to view or replace. Hose must be interspersed or when working with the appearance of the mechanical appearance of the conflict, the use of hose clamps or balusters and other maintenance equipment to prevent damage to the outer layer of the hose. If the hose is necessary to twist, the radius of curvature should not be too small, should be greater than 9 times the diameter. Hose and joint joints should be greater than 2 times the pipe diameter of the straight line. Also recommended for coal commonly used rubber hose specifications.
