I believe that everyone will not be unfamiliar with natural gas, this is currently used more than one, but if the gas does not operate correctly, there are still many security risks, so that when using special attention. Here's a small series to tell everyone about the natural gas hose and how much the size of a gas hose?
How much is a natural gas hose one meter
How much is a natural gas hose one meter , in general, its price is probably at 20 yuan / meter, then its specifications are also 40 centimeters in length, diameter 3 centimeters, and this is still made of high quality tungsten steel, The overall structure seems to be close, tight, and the most important thing is that this material has good corrosion resistance, aging resistance, and compression characteristics, so people who use it are more at ease.
What are the sizes of natural gas hoses?
1. The first thing to know is that stainless steel hoses are made of 304 stainless steel or 301 stainless steel. This material is made of it has good flexibility, corrosion resistance, high temperature resistance, wear resistance, tensile strength, water resistance.
2, metal hose This is a spiral bellows, there is a ring bellows.
3, spiral bellows This is the corrugated spiral arranged tubular housing, and there will be a spiral angle between the two corrugations, all of these ripples can be connected through a spiral.
4. Annular bellows This is also a tubular shell with a corrugated, closed circular ring. This tube is also a series of waves and waves formed by the ring corrugations. And this is also constrained by the processing method. Compared to the spiral bellows, its single tube length is relatively short. The strength of the ring bellows is its good elasticity and stiffness. 
5, corrugated hose This is a kind of flexible pressure pipe fittings in the liquid transport system, but it also compensates the pipe or machine, equipment and the other end of the displacement of the joint, so that it can play a very good vibration damping, silencer, etc. effect.
6, plastic hose is also divided into two kinds, one is completely airtight, watertight, there is a kind of material is wound in series, the general winding bellows it is also used to maintain the cable.
7, PA nylon hose, which is made of imported modified material, it can be a high-tech products, has a high toughness, high impact, good twists and turns, and this product is its high temperature resistance , The appearance of light, while not containing halogen flame retardant, so the scope of use is also more extensive.
Summary: Regarding the natural gas hose, how much is one meter and the size of the natural gas hose? The relevant content is introduced to this, in fact, I believe we all know that there are some hidden dangers in natural gas, so when choosing a pipe to connect it, we must not be sloppy. No leakage occurs, and the consequences are hard to imagine.
Hitachi Launches New TX Series Escalator for
India, Asia and the Middle East
Tokyo, August 21, 2017 --- Hitachi, Ltd. (TSE: 6501, [Hitachi") and Hitachi Building Systems Co., Ltd. today announced the launch of the new TX Series escalator for India, Asia and the Middle East. The escalator has already been released in China*1, and will be released in stages across the remainder regions, commencing August 21, 2017.
In July 2016, Hitachi integrated its escalator businesses of Japan and China, consolidating its resources and enhancing its business operations in both countries, centered around its key business location in Guangzhou, China. The new TX Series escalator launched by Hitachi is a model that meets multiple standards in China, India, Asia and the Middle East. The model follows the same concept for the machine room-less elevator for Asia and the Middle East which was launched in September 2016. In addition to conforming to Chinese safety and quality standards for escalator equipment, the TX Series will be manufactured in accordance with Hitachi's own strict standards of safety and quality, adhering to safety standards in all other regions. It also adopts a functional design based on the concept of an escalator that fits closely with the unconscious actions of users, in the pursuit of their ease and comfort.
The TX Series offers flexibility with a selection of various product specifications, as well as its excellent design and safety features, designed to cater to a diverse range of customer needs. It also saves space required for the installation, covering a smaller area in comparison with existing products*2.
Hitachi will begin sales of the TX Series in Thailand, followed by launches in the Philippines, Malaysia and various other regions, and aims to receive orders of 10,000 units in 2018 in China, India, Asia and the Middle East.
Features of the TX Series
-
Safety
The TX Series offers various new safety features designed with optimal user safety in mind. The side portions of the steps are 8 mm higher than the central portion to prevent accidents in which a users' shoe can become caught between the step and the skirt (side wall) of the escalator. The new TX series has also been fitted with brushes located at foot level on the left and right skirts to let users know if their foot comes into contact with the side walls. A special finish has also been adopted for the landing plates at the entry and exit points of the escalator to prevent users from slipping when getting on and off the escalator. -
Design
The TX Series adopts a simple and functional design that offers the smoothness, safety and comfort that users unconsciously expect to experience when riding an escalator. For example, by minimizing the size of the metal frame supporting the escalator's balustrades, the TX Series' design maximizes the size of the glass surfaces, and achieves greater simplicity at the entrance and exit points (landings) by reducing the number of recesses and protrusions around the hand rail. Additionally, by expanding the installation space of the light fixture, the TX Series also enables enhanced lighting options for illuminating the entire surroundings of the balustrades. -
Space saving
By shortening the span dimensions*3 by 150 mm, the TX Series has made it possible to install escalators in more confined spaces where installation presents difficulties with conventional product designs.
*2 The made-in-China escalator, [SX series," which is previous model of [TX series."
*3 The span between the beam on upper floor and that on the lower floor of the escalator when the escalator is installed.
