How to extend the service life of hydraulic pipes

Litong has been trying various methods to bond rubber, synthetic rubber, especially non-polar synthetic rubber. The self-adhesion of this rubber is too poor, which makes it difficult for the rubber layers to stick together, which requires immediate and appropriate modification. For example, the introduction of resin into the molecular chain can also creatively add polar resin to rubber to improve its performance. The use of the hose must ensure good adhesion, so when using glue and printing, an intermediate transition adhesive layer can be used. The special process adopted by Litong improves the bonding performance.  Hydraulic pipes are relatively fragile parts of the excavation. A basic set of hydraulic tubing is expensive.

 

The most important thing is to prolong the life of the hydraulic pipes. The main thing is that the driver should be gentle when working, not high power and high risk. Sex cycle, in addition to the correct maintenance method, also greatly affects the service life of the hydraulic pipe. Be sure to use protection rings, two do not rub, three do not touch diesel, four lubricating interfaces, and five are installed in place. Customers can maintain their equipment as long as they comply with this standard. Heat-resistant hose vulcanization system: For styrene-butadiene rubber, natural rubber, etc., it is generally appropriate to use sulfur-free (sulfur) or low-sulfur compounding; if peroxide cross-linking is used, a cross-linked structure with better stability can be obtained.

 

If butyl rubber is cured with resin, its heat resistance is better, but the curing time is longer and the amount of resin required is larger. Halogenated butyl rubbers can be cured with peroxide activated systems for good heat resistance. EPDM rubber is basically a saturated polymer with good aging resistance, weather resistance, electrical insulation, chemical resistance and impact elasticity. The main disadvantage of ethylene-propylene rubber is the slow vulcanization rate. While other unsaturated rubbers are difficult to use, the self-adhesion and mutual adhesion are very poor, so the processability is not good. The acid and alkalinity of the dredging medium of the corrosion-resistant chemical hose is very high. When purchasing acid-alkali-resistant and corrosion-resistant rubber joint products, the dredging medium is 50% ammonium sulfate, which is a strong acid, which brings a huge test to the material performance of the product. Therefore, users choose EPDM rubber joints for use in corrosion-resistant chemical hoses.

 

The length between the pump of the oil pipe and the drill frame, i.e., the branch pipe of the riser, is generally greater than 135m, and the shock-absorbing hose is short (9m or less), which is suitable for different axial and isolation vibrations. The tissue editing consists of inner rubber layer, inner rubber protective layer, middle rubber layer, steel wire winding layer and outer rubber layer. The hose liner must consist of oil and water resistant rubber. The hose reinforcement consists of woven and steel wire (rope) materials.  Passing ABS certification shows that the industrial technology level of our company's products has reached the world-class level, and we are qualified to produce and supply related marine products in accordance with ABS standards, which will expand the industrial structure of our products. company and will enter the international shipbuilding and oil industries. The development of the drilling and mining market also shows that Litong Manufacturing has entered a new stage of high-quality development in the international market.
