Yunnan Luliang natural gas well injection well succeeded

At 10:10 on the 3rd, after a long and intense operation, the natural gas blowout in Luliang County, Yunnan Province, was successfully controlled. The incident had raised concerns among local residents and authorities, but with careful planning and swift action, the situation was brought under control without any casualties. At the site, an official from Sinopec Southern Exploration and Development Branch told reporters that the blowout's intensity began to decrease early in the morning of the 3rd. Seizing the opportunity, the team decided to implement the first well-killing plan ahead of schedule, starting the operation around 9:00 AM. They worked quickly to regain control, and by 10:10, the initial attempt to kill the well was completed, though it was not entirely successful at first. Reporters on the scene observed several workers wearing protective gear, continuously spraying water on the wellhead to prevent any potential hazards. After the well was finally secured, some staff members were still conducting inspections to ensure everything remained stable. Xu Desheng, the deputy county magistrate of Luliang County, who was directly involved in the emergency response, told Xinhua News Agency, "Thanks to the coordinated efforts of all parties involved, the preparations were largely completed in advance, allowing us to start the operation several hours earlier than planned. There were no injuries at the well or the killing site, and no risks were present." Xu also informed reporters that the affected residents would be allowed to return to their homes in the afternoon of the 3rd. He added that the necessary follow-up measures, including environmental monitoring and safety checks, would continue in the coming days to ensure the area was fully secure.

PFA Products

PFA also known as soluble polytetrafluoron, is actually a modification of PTFE which has excellent comprehensive properties but can not be fused, and retains almost most of the PTFE. PFA is better than FEP in high temperature resistance and stress cracking resistance, good bending resistance, mechanical strength at high temperature is better than PTFE, long-term use temperature -196- 260 degrees, just because the cost and price of PFA is almost twice that of FEP and more than three times that of PTFE, so PFA in many fields to the application.

Material properties
1, excellent resistance to high and low temperature chemical corrosion, corrosion resistance to all chemicals, chemical resistance is similar to PTFE, better than vinylidene fluoride.
2, low friction coefficient, friction coefficient is low in plastic, has good electrical performance, its electrical insulation is not affected by temperature, known as the "plastic king".
3, the creep and compression strength are better than PTFE, high tensile strength, elongation can reach 100-300%. Good dielectric property, excellent radiation resistance.
4, crystalline material, small moisture absorption. Can be processed into products by the usual thermoplastic processing method.
5, because the molten material has corrosion effect on the metal, long-term production, the mold needs plating chromium treatment.

Feature:

High and low temperature resistance: -200--200℃, high temperature strength than F4 two times
Excellent adhesion and heat sealing with F4: NO wetting with any object below melting point. Above the melting point, it has good adhesion with F4 and metal. And self bonding (heat seal)
Non-viscous, water, oil: water contact Angle θ=115о
Electrical reliability, high insulation
The dielectric constant viscosity is 2.1 at both high and low temperatures of 60HZ-60mhz. Even if the surface is damaged by diving, no conductive track will be created.
Volume resistance > 1018 ω M
Surface resistance > 2*1013 ω
Arc resistance > 165 seconds without leakage
Weather resistance: can be exposed to ozone and sunlight for a long time
Corrosion resistance: ONLY at high temperature, the element fluorine, alkali metals with it, to all other concentrated, dilute inorganic organic acids, alkali, esters are not effective

Application:

Its main use is for the production of tubes and chemical equipment of the village, the surface of the drum and a variety of wires and cables, such as aircraft hook line, supercharged electricity
Cable, alarm cable, flat cable and well logging cable. FEP films have been seen as thin coatings for solar collectors. Mainly used in communication electricity
Cable, wire, semiconductor, chemical anti-corrosion, medical materials, automotive, industrial coatings and other fields.
