RubberJoint Quality Affect It's Performance
Rubber joint quality does have great effect on the performance of rubber expansion joint, high-quality rubber joint material is sure to make pipes more long-te
It is a very dangerous thing if the oil leakage occurs in the car shock absorber. So, once the oil leakage is found, what are the remedial measures? Today HuanZhong will talk to you about how to deal with the car shock absorber when oil leakage failure oc
1. Double sealing design (bellows + packing) If the bellows fails, the stem packing will also avoid leakage and meet international sealing standards.
2. Environmental protection, no fluid loss, reduce energy loss and improve plant equipment.
There are several precautions when using waterproof casing, and now HuanZhong and you will talk about them.
the basement outside the waterproofing work surface, can be used to prevent the outside of the internal paste method, there are conditions to turn
Double flange limit expansion joint installation and use requirements are very strict, of course, its methods and requirements are also different, we can only m
Mainly used in the pipeline is mainly to ensure that the pipeline thermal expansion and contraction when there is an expansion, otherwise it is a hard connection will be a problem. There are other roles such as used in the valve inside, to do the effect o
Expansion joint cleaning method: the application of chemical washing method to stop washing, then it is necessary to apply to the chemical, washing method is to stop a temporary transformation of the pipeline, with temporary pipeline and recycle pumping s
For different use requirements, the connection between the bellows, the mesh sleeve and the joint includes welded, mechanically clamped and mixed three.
Their installation length is different, the standard length of flexible casing is 300mm while the standard length of rigid casing is 200mm, but they have a common point is that they can be lengthened or shortened at will for construction needs.
1. Compensation expansion: can compensate for multiple directions, greatly superior to the metal expansion joints can only be single type compensation.
2. Compensation for installation errors, due to the pipeline coupling process, the system error is
1. It is strictly forbidden to exceed the displacement and elongation of the rubber soft joint during installation.
2. The installation bolts should be symmetrical and gradually pressurized and torqued to prevent local leakage.
3.Above 10kg working pres
After the installation of metal expansion joints, remove the transport tie rod and limit nuts before the test pressure, you need to check that the moving parts of the metal expansion joints can work properly.
The heat resistance of all rubber joints is around -20℃-150℃, which can't be used in the natural environment that is too polarized. When rubber joints are buried, the buried protection equipment should be modified to avoid rolling. When installing, rubbe
Flexible and rigid waterproof casing through the wall of the wall, such as non-concrete walls should be replaced with concrete walls, and the casing must be solidified in the wall once; rigid waterproof casing is generally applicable to the pipeline throu
First, the expansion joint application time period is too long, the expansion joint in the silicone ring selection is a new type of natural rubber, the general term in at least five years, if the application time exceeds five years, may cause leakage due
① trimming of the cut edges of rubber molded products to make the surface of the products smooth and the shape size meet the requirements.
② After some special technology processing, such as the surface treatment of the products, so that the use of speci
When installing rubber expansion joints in pipeline construction, let them be in a normal state and do not artificially deform the product during installation. This can avoid causing early damage to the product and weakening of the use effect. Flexible ru
