First, the most commonly used models: braided high-pressure adhesive 2-10-40 MPA, braided high-pressure adhesive 2-16-21 MPA, the largest amount.

二，其他常用型号：1，编织高压胶管有：编织高压胶管2-13-30MPA，编织高压胶管2-19-18MPA，编织高压胶管2-25-14MPA，编织高压胶管2-32-11MPA，编织高压胶管2-51-8MPA。

2，缠绕高压胶管有：缠绕高压胶管4-10-70MPA，4-13-60MPA，4-16-55MPA，4-19-46MPA，4-25-35MPA，4-32-32MPA，4-51-20MPA。

2, winding high-pressure hose: winding high-pressure hose 4-10-70 MPA, 4-13-60 MPA, 4-16-55 MPA, 4-19-46 MPA, 4-25-35 MPA, 4-32-32 MPA, 4-51-20 MPA.

最后，我补充一下，编织高压胶管2-38，跟缠绕高压胶管4-38。这2个型号用量很少。想必做矿用高压胶管的朋友都知道。另一个方面，肯定有朋友问我。为什么3层的高压胶管没有呢？今天我在这里详细说明下，前几年，我在国家煤矿安标中心培训过，曾经在一节堂课里，听一位老师讲，3层跟2层的编织管压力都差不多。所以没必要做3层。如果2层，压力真吃不住，那么3层也肯定不行。要么直接换成缠绕4层。再加上，国家崇尚节能减排。所以不提倡使用3层。

Finally, I would like to add, braiding high pressure hose 2-38, and winding high pressure hose 4-38. The 2 models are very small. Friends who want to use mine high pressure hose know that. On the other hand, there must be friends asking me. Why is there no high-pressure hose on the 3 floor? Today I am here to explain in detail below, a few years ago, I trained in the National Coal Mine Safety Standard Center, once in a class, listened to a teacher, three layers and two layers of braided pipe pressure are similar. So there is no need to do 3 levels. If the 2 floor, the pressure is really unable to eat, then the 3 tier is certainly not. Or replace it directly with 4 layers. Moreover, the State advocates energy conservation and emission reduction. So do not advocate the use of 3 tiers.
