Shanxi Yulin 500mm mining positive pressure air duct flame retardant and stretchable 500mm mining negative pressure air duct fabric manufacturer

Description :

1、 500mm mining positive pressure air duct:

　　The 500mm negative pressure air duct for coal mines is suitable for underground mining work in various mines, local fan positive pressure ventilation, and positive pressure ventilation in tunnel engineering. The engineering air duct adopts the high-temperature and high-pressure cylindrical integral one-time molding technology, with no longitudinal joints, and has the advantages of flame retardancy, anti-static, low wind resistance, no air leakage, and high strength. It is suitable for supporting local ventilation fans in coal mines and tunnel engineering as forced ventilation. The 500mm negative pressure air duct for coal mines is refined using advanced high-pressure heat sealing technology with seamless billets and high elasticity spring steel rings. It has the advantages of good suction effect, easy turning, convenient transportation and storage (each section is individually packaged), and longer service life. It is suitable for ventilation and dust removal in coal mines, especially for gas extraction and ventilation in tunnel engineering.

2、 Specification and size of 500mm positive pressure air duct:

　　1. Wind tube varieties: Wind tubes are divided into rubber coated negative pressure wind tubes, plastic coated negative pressure wind tubes, and rubber coated negative pressure wind tubes according to the coating material.

　　2. The connection between the air duct sections is made using quick connector soft tape:

　　3500mm negative pressure air ductSize:

　　The diameter of the air duct refers to the diameter of the end ring; Special shaped ducts, elbows, tees, etc. with special specifications can be sold according to the requirements of the demand; If there are special requirements for the specifications of metal accessories such as wind duct lifting rings and end rings, they shall be agreed upon by both parties; Each end of the air duct is equipped with a joint reverse edge cloth, with a length of 150mm-200mm. We can customize specifications according to the actual needs of customers.

IIIPositive pressure negative pressure air ductPackaging, storage and transportation:

　　1. Compress the negative pressure air duct axially to a length of less than 700mm, fix it 3-4 times with ropes or cloth strips, and then package it with high-quality materials;

　　2. During transportation, negative pressure air ducts should be protected from mechanical impact and friction, as well as from direct sunlight and rain;

　　3. Negative pressure air ducts should be stored in a well ventilated warehouse, and should not be placed too high to avoid affecting the quality of use. Used air ducts should be washed and dried first, and then folded for storage. Contact with substances that damage the quality of rubber and plastic is prohibited, and direct sunlight and rain should be avoided. The storage temperature should be between -15 ℃ and 35 ℃, with a relative temperature between 45-75%, and at a distance of 1 meter from the heat source;
