Q: Can the natural gas hose not exceed 1.5 meters or 2 meters?
If the gas is longer, to Caution! Protective tube wall, as far as possible, to prevent accidental damage risk of gas pipe.
Q: What advantages does the Parker hose have in comparison with other hydraulic hoses?
First: from the price point of view. The price of PAKER is the most expensive in the whole industry. High popularity.Second: if in terms of quality. With his quality, Ma has worked hard. Eaton. Love hair. The quality is all rightThird: from the point of view of use, the difference is not obvious. PAKER things match well
Q: What is the essential difference between rubber expansion joint and rubber joint?
The expansion joint is also called expansion device, expansion joint and compensator. It is divided into several types, such as ripple compensator, sleeve compensator, rotary compensator and square natural compensator, and also has intubation type expansion joint. Among them, the corrugated compensator is more commonly used, mainly to ensure the safe operation of the pipeline, and has the following functions: 1.. Compensating the axial, transverse and angular thermal deformation of the absorption pipeline. 2. vibration absorption equipment to reduce the impact of equipment vibration on the pipeline. The deformation of the pipeline 3., absorption of seismic subsidence.
Q: Standard for implementation of type KXT-1 rubber joints
This product can reduce vibration and noise, and can be compensated by thermal expansion and cold contraction due to temperature changes. It is widely used in various piping systems. Rubber joint manufacturing standard CB-T 965-95 CJT208-2005 to take over the compensation rubber flexible rubber joint CJT 3013.1-1993 KST flexible rubber joint
Q: What are the types of cable metal hose connections?
It is mainly used for connecting the box and hose in place. Open the box in the box and plug into the joint. The external thread joint is fixed with the lock.
Q: The difference between silicone tube and PVC tube
PVC pipe is made of polyvinyl chloride resin and stabilizer and lubricant with injection molding machine with hot extrusion molding, main performance, electrical insulation; chemical stability; self extinguished; low water absorption; easy adhesion, high resistant to high temperature of about 40 degrees. Main appliances, industrial gases, liquid transportation, household sewer pipes, water pipes and so on. Environmental issues: plasticizer, antioxidant and other added accessories are toxic, daily in PVC plasticizer, mainly using terephthalic acid two butyl phthalate two formic acid two ester etc., these chemicals are toxic.
Q: How do the automobile rubber hoses combine with the quick couplings?
Turn the rotary handle on the quick connector to the open position first;
Q: Do the rubber joint and Y filter need flange connection?
Rubber hose joints are usually externally threaded, and type Y filters are internally threaded and are directly connected to the same caliber.Flange connection also has ah, according to demand
Q: Flex rubber joint installation skills, what are the materials of rubber soft joint?
Rubber soft joint material:Ordinary water, acid and alkali resistant, oil resistant rubber, high temperature resistance, low temperature resistance
Q: What's the difference between hose and hose for compressed air?
When the joint is made into a quick plug, hard pipe is rare; for example, galvanized steel pipe, joint practice is similar to hydraulic tubing. The pipes in the compressed air are welded with steel tubes, but I don't think that's what you call the hard tube
