In fact, on the smoke control and exhaust pipeline, the important thing is what kind of sealability will be. Only when they improve the sealability on the product, will they be used on the product, and the quality of users will be satisfied. So how can we achieve their sealability on this product? First of all, it depends on what design they have. Good design naturally means that the quality of the product is fundamental. Naturally, there are also some manufacturers. In their own production, they just don't have good design advantages.

　　所以在这样的情况下，才会在用户的使用中，就没有很好的满意，还有一点，就是在防排烟管道的生产中，都是会有什么样的一个技术的表现，好的技术，能造就好的工艺性，而在好的工艺性之下，自然他们在产品上面的本、和使用中，才会有自己的多方面提高，所以这也是其中之一，当然除了他们在自己的产品上面，能让自己来进行很好的设备上面的条件。

　　Therefore, in such circumstances, only in the use of users, there is no good satisfaction. Another point is, in the production of smoke control and exhaust pipes, what kind of technical performance, good technology, can create a good craftsmanship, and under good craftsmanship, naturally they are on the top of the product. In use, will have their own improvement in many ways, so this is one of them, of course, in addition to their own products, can let themselves carry out good equipment on the conditions.

　　在这种金属一类产品加工的时候，重要的也是在于设备，巧妇难为无米之炊，如果是一个公司，他们在自己的设备上面没有相对的提高，即使在防排烟管道上面有自己的技术，也不能让他们在产品上面，能真正达到提高，所以这也是产品使用中，需要来进行注意的一个方面，好的设备，能让产品在拼接上面，相对有很好的质量性，这样也就提高了产品上面的密封性，所以所说的密封性，就是在于整个生产上面的实力。

　　In the processing of such metal products, it is also important to equip them. Smart women can hardly cook without rice. If they are a company, they have no relative improvement on their own equipment. Even if they have their own technical advantages on smoke control and exhaust pipes, they can not really improve their products. So this is also one aspect that needs to be paid attention to in the use of products. Good equipment can make the products on the splicing surface have relatively good quality, which also improves the sealing of the products. So the said sealing is the strength of the whole production.
