Vacuum Insulation Tubing & Casing
Vacuum Insulated Tubular is one of the essential equipment for the steam injection thick oil recovery.
Shengji owned 2 seamless steel pipe production lines, 3 VIT tubing production
lines, 7 tubing & casing processing lines and 2 steel pipe upsetting lines.
The annual production reaches 1 million meters.
The products have been provided in many oilfields of China and exported to
Canada, Oman, Kazakhstan and etc. In Shengli Oilfield, market share of SJ Vacuum
Insulated Tubular exceed 80% in 3 years.
Key Feature
1. For conventional thermal recovery under 380℃ and supercritical environment
of 400℃
2. Well depth can reach 1500 meters
3. With good quality control system, 85% of grade E, and the rest are grade
D.
4. Been sold to Canada, Kazakhstan, Oman.
5. Internal connection, External connection and Direct connection
6.Stable and reliable in quality. Defect detective 100% before delivery.
Insulation Type
Shengji Vacuum Insulated Tubular has A variety of heat insulation materials,
currently mainly used aerogel and Gridding Cloth Aluminium Foil.
aerogel is a nanoporous solid state material. Because of its low density,
aerogel is known as the lightest solid material in the world. Aerogels have
outstanding properties in thermal, acoustic, optical and mechanical fields due
to its fine nano porous structure and large surface area. Aerogel insulation
felt is made of special fiber yarn as the base material, and is prepared by nano
composite process. It is mainly used for thermal insulation of heavy oil high
temperature steam injection pipeline and the insulation of the refinery device
medium pipeline. The general temperature is between 200 ~500℃. Aerogel products
are light and have excellent hydrophobicity, hydrophobicity rate is more than
98% and pH value is neutral. It will not corrode the heat preservation pipeline,
thus prolonging the service life and reducing the later maintenance cost.
