Protective clothing: make safety more reliable

In addition to researching and developing air breathing apparatus, Fushun Huateng also devoted a lot of research and development to protective clothing. It is reported that the company has three series of protective clothing, mainly FHT-RFH-B series of sealed digestive chemical protective clothing, HTZF series of human protective clothing and fire escape clothing.
According to the company's relevant personnel, FHT-RFH-B series of sealed digestive chemical protective clothing is a kind of special protective clothing that is used in various industries when chemical spills or explosions cause malignant accidents. It is also mainly used in fire, petrochemical, chemical, military, metallurgical and other industries. When dealing with chemical events, it is worn when it comes to rescue accidents at the scene of chemical dangerous goods, corrosive substances and toxic gases. This series of protective clothing is a metal sealed zipper. At the same time, thanks to its special materials, it can achieve flame-retardant, heat-insulating, respiratory protection and skin protection. It is well-designed, with a wide hood design to facilitate observation of the outside world. There is a ventilation system inside, and an overpressure exhaust valve makes it feel safe and comfortable. In the specific construction site, it is dressed quickly, oil-resistant, acid-proof boots, anti-smashing, puncture-proof function allows users to be very favored.
HTZF series of human protective clothing is divided into five models, this series of products use double-sided butyl adhesive silk fabric, is a high-strength cotton silk fabric as the substrate, made of whole body structure, the product has also been national labor protection supplies Quality Supervision and Inspection Center passed the test. This series of products are also mainly used in emergency rescue and disaster handling in toxic and hazardous gas environments or in aggressive media. HTZF-1 type positive pressure human protective clothing is specifically applicable to the external air source and vehicle-mounted positive pressure long tube air breathing apparatus and backpack air breathing apparatus. HTZF-2 positive pressure human protective clothing is used together with air respirator for emergency rescue. HTZF-3 type positive pressure human protective clothing can wear air respirator, oxygen respirator, canisters and other masks for rescue operations. HTZF-2A positive pressure human protective clothing can be used for air respirator and oxygen respirator use, anti-acid and a variety of toxic gases. HTZF-2C positive pressure human protective clothing can be used for air respirator and oxygen respirator, anti-acid and alkali and various toxic gases.

In addition, Fushun Huateng also produced a fire escape clothing. This fire-retardant suit consists of a hood, tops, underpants, gloves and boots. It conforms to the Q/02TXF002-2000 standard. It adopts fire-retardant fiber cloth, fireproof layer, fire-resisting insulation layer and waterproof layer to block fire-retardant layer on materials. , comfortable eyepieces, gold-plated safety glasses. Because its flame resistance temperature reaches 1000°C, it can be used when crossing the fire zone or entering the flame zone for a short time.

Microbend Mass Flow Meter

Sealand is a trustworthy manufacturer of Microbend Mass Flow Meter, Microbend Mass Flowmeter, Microbend Coriolis Mass Flow Meter, Microbend Coriolis Mass Flowmeter.

Site Selection for Mass Flow Meter Installation
a) Sensor stays away from mechanical vibration source, for example, pump. Use flexible pipe to connect meter with pipeline if inevitable. The housing of meter must be standalone, out of touch with any other device. There must be 3 times the size of sensor between 2 sensors if there are many flow meters on the same pipeline, to avoid resonance.
b) Do not install sensor on pipeline that easily expands with hot and contracts with cold, especially near expansion joint, which leads to a worse stability.
c) Sensor stays away from industrial electromagnetic field, such as large generator and transformer, better 5m at least. Such device influences the performance of drive coil and pickoffs. Make sure magnetic field intensity less than 400A/m.
d) Sensor shall be installed on lower pipeline, to be easily full of fluid.
e) Make sure Ex-mark meet application requirements if in hazardous area.
f) Build a sunshade if the meter is under direct solar radiation. g) Keep the meter from corrosive liquid.
