　　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.

　　所以在這樣的情況下，才會在用戶的使用中，就沒有很好的滿意，還有一點，就是在防排煙管道的生產中，都是會有什么樣的一個技術的表現，好的技術，能造就好的工藝性，而在好的工藝性之下，自然他們在產品上面的本、和使用中，才會有自己的多方面提高，所以這也是其中之一，當然除了他們在自己的產品上面，能讓自己來進行很好的設備上面的條件。

　　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.

　　在這種金屬一類產品加工的時候，重要的也是在于設備，巧婦難為無米之炊，如果是一個公司，他們在自己的設備上面沒有相對的提高，即使在防排煙管道上面有自己的技術，也不能讓他們在產品上面，能真正達到提高，所以這也是產品使用中，需要來進行注意的一個方面，好的設備，能讓產品在拼接上面，相對有很好的質量性，這樣也就提高了產品上面的密封性，所以所說的密封性，就是在于整個生產上面的實力。

　　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.
