Sandblasting hose is braided with special steel wire for copper-plated hose, which can withstand working pressure 3-4 times that of cloth hose. It has a high degree of pressure resistance and superior anti-flexion performance. The name of the sandblast hose is sandblasting rubber hose, which is mostly used for metal blasting and ramming. In addition, it can be used for wet blasting and dry blasting of construction works. The fields it uses are mostly mechanical processing, shipbuilding and spraying. Each item has its own standard. The sandblast hose standard many people want to know. Today, I came to talk about the blasting hose standards and related knowledge.
Sandblasting hose features
Inner rubber: Polyurethane and butyl rubber are used as the main raw materials, and special reinforcing agents are added. The plastic color of the finished product is a yellow transparent state, with high wear resistance, high toughness, high pressure resistance, etc. The wear resistance index is 2-3 times that of ordinary sandblasting hoses.
Enhancement layer
The cloth sandblasting hose adopts high-quality rubbing cloth as reinforcement layer, which has good flexibility and strong pressure bearing capacity;
The steel braided sandblasting hose adopts special steel wire braided with copper-plated rubber hose, which can withstand working pressure 3-4 times that of cloth hose. It has high pressure resistance degree and superior anti-flexion performance.
Sandblast hose type
Sandblasting pipes are generally divided into light sandblasting pipes and heavy sandblasting pipes according to working conditions and the loss degree of the material particles to the conveying medium. The spiral steel wire will make it suitable for the negative pressure environment.
1. Lightweight sandblasting tube
It is usually used in the environment such as sandblasting of ships, quicksand operations, etc. The common inner rubber is made of wear-resistant NBR (natural rubber) material, and the outer rubber is packaged with a compound adhesive.
2. Heavy duty sand blasting pipe
Used for sandblasting, fine pebbles, mud, etc.
3. Sandblasting vacuum tube
Embedded spiral wire, the general vacuum negative pressure can reach 0.9 bar.
Sandblasting hose specifications
Sandblast hose specifications: inner diameter (mm) 51, 63, 76, 102, 125, 152 wall thickness (mm) 6.5, 6.5, 7.5, 8, 8, 10.5 outside diameter (mm) 64, 76, 91, 118, 141 173
Sandblast hose standard
1. Technical standard of sandblast hose
Only standard products can provide users with peace of mind. Next, talk about its technical standards.
In the use of temperature, the temperature of blasting hose is generally -20 - 70 degrees Celsius.
In terms of materials and structure, the blasting hose should have the following structure. The first needs an inner glue layer. Second, there is a reinforcing layer, which consists of a natural or composite paved by a suitable method, and it is mostly made by the sandwich cloth method and the cord winding method. Third, it has an outer rubber layer.
In terms of hydraulic pressure, its standards are as follows. The working pressure of the blasting hose is a maximum of 0.63 MPa. When it performs hydraulic test work under double working pressure, it is not water seepage, and local bulging, swelling and other abnormal phenomena cannot occur.
Its anti-static hose should maintain pressure for one minute, but the change of length can't exceed 0.8% of the upper and lower, the change of the outer diameter can't exceed 10% of the upper and lower, but for every meter, the rotation can't exceed 60 & ORDM. Finally, the burst pressure of the blasting hose must not be less than 4 times the working pressure.
2. Bending hose standard
At 23 degrees Celsius, when using an experiment with a minimum bending radius of 10 times the nominal diameter, the deformation value must not exceed 0.8 times the outside diameter, and at -25 degrees Celsius, it should not be cracked after bending.
3. Wear standard
This is also the main basis for judging the quality of blasting hoses. In the current standard, according to the ISO 4649 method, the abrasion volume of the blasting hose should not exceed 140 MM&SUP3. In addition, the strength of the interlayer adhesion of the blasting hose, as well as the ozone resistance index and mechanical properties (under verification pressure) are also sprayed. Sand hose quality indicators of important indicators.
Sandblasting hose manufacturers
"Yulong" brand sandblasting hose is produced by the Jiaozuo Risheng Pipe Industry Technology Co., Ltd., Henan Province.The brand also has various kinds of rubber hoses, such as steel wire textile hoses, wire suction hoses, and cloth pressure hoses. The technology tests and maintains the product to ensure the quality of the product, and the factory has achieved numerous honors and awards over the years since its establishment, and the quality and reputation are never bad.
The plant has a history of nearly two decades. In Henan, Shanxi, and Xi'an, there are direct sales offices for products and a large sales network has been established. It is not difficult to see that this developing company has prepared for the expansion of production scale and product quality.
Editor's summary: "Yulong" brand sand blasting hose is reasonable in price and of good quality. It is a good helper in construction projects. A good blasting hose allows you to save time and improve work efficiency during construction. If the price is reasonable and there are purchase channels, we will of course choose a cost-effective one.
