Hebei Baoshi Special Flexible Rubber Chemical Industry Co., LTD is the manufacturer of different types of Union series, which include High Pressure Union, middle pressure union, and low pressure union, with 12 years experiences, ISO, OHSAS & API certificates, this is how we keep quality and competitive price for global valued customers.
HIGH-MIDDLE-LOW PRESSURE UNION
Figure 602
With resilient nitrile-butadiene rubber seal ring, this figure is used for sealing and protecting the steel-to-steel match.
It is recommended for the connnection of mainfold and pipe and truck-mounted application and mud delivery. It may be used as pressureless seal union with butt weld Sch. 80.
Figure 1002
Resilient nitrile-butadience rubber seal ring is mounted.
It is recommended for cement filling, fracturing, acidizing, testing and choke and kill line. It is designed for high-pressure systems including truck-mounted system. Also, it may be used as pressureless seal union. Butt weld Sch. 160 or XXH is desired.
Figure 1003
With an spheric seat, the union allows a deviation by 7-1/2° from the center or angle adjustment with a total deviation capacity of 15°. In addition to the steel-to-steel match, the nitrile-butadiene rubber O-ring ensures air-tightness in connection at any deflected position.
Figure 1502
With replaceable resilient nitrile-butadiene rubber seal ring and robust wall thickness design, this figure is used in high-pressure system.
It is commended for comment filling, fracturing, acidizing, testing and chock and kill line. Also, it may be used in pressureless seal connection. Butt weld Sch. XXH is desired.
Figure 2002
For this union, only the 2in type is available with a replaceable resilient nitrile-butadiene rubber seal ring combined in the stainless steel liner tube, providing complete compression protection in application with extra high pressure. The design of detachable nut/segment ring/simplifies the removal of the nut from the piping.
Figure 2202
With fluoroelastomer seal ring, 15000PSI NSCWP and the heat-treated parts 100% subjected to hardness test, this model complies with National Association of Correction Engineers Standard MR-01-75 and American Petroleum Institute RP-14E.
This product is designed for application with acid gases. Green nuts and parts.

1, handicraft issues
When many people do it by hand, the infrared light is not concentrated, astigmatism; scattered light leads to light everywhere, but a gray phenomenon; cotton light block in front of the infrared light is not tight, concentrated infrared red light is a vast phenomenon.
2, lack of current causes snow point
Some outdoor short-distance use of centralized power supply 12V is convenient, but long-distance infrared light generates large heat, 12V power supply instability may lead to insufficient power; and all without built-in heat sink device is prone to burnout in the case of current instability; second is the current Attenuation of the speed block may cause the infrared lamp to fail to work properly. The illuminance of the CCD is relatively high and the auxiliary light of the infrared lamp cannot be obtained, so the snow flutters.
3, poor quality infrared light, infrared light angle and infrared distance with the lens does not match the snow drift. Many companies use a mixture of different angles to facilitate their own purchases and installations. The advantage of using them is that they can barely use different millimeter-sized lenses for the same type of lamp. The disadvantage is that people always feel the light's angle. With the distance and the lens is not suitable, when the angle is not suitable, flashlight phenomenon or narrow electric phenomenon is likely to occur;
4, the circuit design is irrational
The production of infrared cameras is not only the installation of infrared light directly into the camera and then on the line, and the second is to redesign and aging the camera circuit before installation. Many small-scale processing plants on the market use cheap electronic components, buy inexpensive infrared lamps, and directly use soldering irons for soldering. There are no redesigns or aging processes for circuits. In addition, some factories that manufacture low-end products want to save money. The control circuit board control board removed or integrated with the light board, which can easily lead to infrared light by the circuit instability and heat, so that the poor quality of infrared light even more can not work.
5. Another possibility is that in the case of more dust outside, especially in the field, it may be that the camera's infrared lamp shoots fine particles that are invisible to the naked eye. This does not turn on the infrared light during the day. Under the naked eye and the camera does not feel obvious; this is the environment.
6, the built-in is a poor camera, illumination is very high, many factories in order to obtain a brighter image under the same infrared light auxiliary light, artificially increase the sensitivity of the CCD; because many manufacturers use very poor for price competition Built-in camera, this kind of camera in the case of infrared light is insufficient light, so artificially increase the gain sensitivity of the CCD, with us on the hard disk video recorder to adjust the high brightness, is very easy to appear snow phenomenon;
2. Large stocks Timely delivery
3. Professional
4. Good after-sale service
