with the tensioner bolt preload key reasons

We all know that can replace hydraulic adapters  wrench to tighten the large diameter of human vital bolts,hydraulic nut bolt tensioners actually allowed in space can also be at play the same role. Hydraulic bolt tensioners (abbreviated stretching device), also known as hydraulic bolt tightening device or hydraulic bolt tensioners, in the early introduction of urea plant along with the imported equipment sold to China, now this tool is gradually being received. Compared with hydraulic wrenches, bolt tensioners supplied along the axial preload, so the bolt preload process in almost no torsional stress, so after tightening the bolts equipment into working condition, the bolt may suffer greater stress, for sentences words, bolt safety factor, so, nuclear pressure vessels, mainly based on chemical containers are applied tensioner bolt preload. Of course, the application is not just the interests of pretension stretcher these.

How quickly and accurately identify pipe fittings thread
The thread gauge gages, test tube fittings, this is the most accurate.

Quick connector daily use problems

In the cable connection, quick connector end is for different style of plug interface, the other side of the connection also want to install the corresponding plug, which can well realize rapid insertion function. Quick connector is not suitable to the large current cable, because the current skin effect, most of the current in the cable surface circulation, if quick connector make two root cable in the contact surface is not allowed, will be in a cable surface caused great resistance, large current through the, according to the joule's law will have a great quantity of heat and burned the danger of cable.
In the pipeline connection, it has two kinds of structure forms: open closed and open ends at both ends. Both ends open closed, two joint body each have a check valve, two joint separation, check valve closed and hydraulic hose fitting, line of the liquid can't outflow, two joint connection, check valve open, line connected. Both ends open, there is no check valve, two joint apart can't closed line.

Fittings can be classified into two categories: standard accessories and optional accessories. Standard fittings is refers to the random equipped with auxiliary parts. Although each type of standard configuration is different, common standard configuration parts have memory and for carton and stainless steel flange. Of course for different type, memory size and capacity for carton is different. The standard configuration can by looking at the product description to understand. If lack of standard configuration of words, in a certain extent affect the use of the products and performance.
Optional accessories refers to the standard configuration, but can enhance product function, improve the performance of the product components, is the need to buy another. And the standard configuration is different, do not use optional accessories will not affect the use of basic product functions. Optional accessories is a lot of more phyletic, different product support optional product also is different, so in the choose and buy optional accessories should be prior refer to product descriptions, lest bought can't use.
