It has provided damping products and professional technical services for the petrochemical industry, including Yanshan, Daqing, Lanzhou, Yangtze-BASF, Maoming, Sailboat, Zhongtian Hechuang, Yangtze, Uhde HPT, and MES etc., as well as system damping solution for pipeline vibration in petrochemical plants in China.

High pressure, ultra-high pressure damping supports (pressure: ≤340MPa) for EVA & LDPE plants
Damping supports for inlet/outlet pipelines of dynamic equipment, e.g. compressor and pump (pressure: ≤50MPa)
Damping supports for double phases (gas and liquid) pipelines (pressure: ≤50MPa; temperature: ≤400℃)
Damping supports for pneumatic transmission system pipelines (temperature: ≤150℃)
Cold pre-insulated & damping supports for deep cold pipelines (-196℃≤ temperature ≤120℃)

Spring supports and hangers are in two types: variable and constant. The spring support and hanger contains cylindrical helical spring and can bear load while adapting to thermal displacement of equipment and pipelines. Under permissible load, constant spring supports and hangers can always maintain balance between load torque and spring torque, and provide constant support force, without producing additional stress on equipment and pipelines.

Variable spring supports and hangers have displacement range of 0~120mm, load range of 154~217384N, and operating environmental temperature range of -20℃~200℃.

Constant spring supports and hangers have displacement range of 50-750mm, load range of 160~400000N, and operating environmental temperature range of -20℃~200℃.

Sunpower Piping started to study special support design and manufacture technology for high temperature reaction zone of propane dehydrogenation plant in 2010, and provide clients with technical consultancy service and scheme design service etc. Through overall film stress analysis and local stress analysis for high temperature pipelines and special supports, special supports that support pipelines and limit their positions under ultra-high temperature (704℃) ultra-large axial load (250T) operating conditions have been designed, completing special supports design, manufacture, installation, and commissioning services for a number of PDH projects home and abroad.

Sunpower ultra-low friction pipe supports are pertinent  by a joint professional technical force (this company along with universities and scientific research and design institutes) via finite element analysis and simulation experimental verification, based on understanding relevant technologies home and abroad and comprehensive application of materials, structure, and stress technologies.   Since their friction coefficient is less than 0.03, horizontal friction on equipment and pipeline saddles is greatly reduced, improving safety of pipelines and equipment nozzles.

Ultra-low friction pipe supports have applicable load range of 5000~8000000N and operating environmental temperature range of -20℃~200℃.

Cold  support is a low temperature/ultra-low temperature high efficiency energy saving pipe support product.  Core coldness maintaining parts of this type of pipe support adopt foaming raw materials of BASF and DOW.  In combination with special formulary technique and manufacture process of SUNPOWER, coldness maintaining materials of stable performance and long service life (HD-PIR and HD-PU) have been manufactured, and feature low heat conduction coefficient, strong resistance to pressure, strong resistance to folding, excellent flame retardant performance, and strong resistance to aging.   These pipe supports are highly appraised by clients home and abroad.

Cold supports have pipe diameter range of DN15~DN2000, applicable load range of 2000~600000N, operating environmental temperature range of -200℃~150℃, and cold block thickness range of 30~300mm.

Sunpower Piping is a company that performs R&D and production of hot supports, being high efficiency energy saving type pipe support products.  Sunpower hot supports adopt autonomously developed inorganic high efficiency composite thermal insulation layer that features low heat conduction coefficient, high resistance to pressure, and high anti-folding strength, effectively solving the problem of “thermal bridge” in pipeline thermal insulation system, and saving energy by more than 60%, winning high appraisal by clients.

These hot pre-insulated supports have pipe diameter range of DN15~DN1000, applicable load range of 5000~850000N, and operating environmental temperature range of -45℃~1000℃.

Stabilizing supports and hangers (universal rigid stut): They can adapt to both vertical displacement and angular displacement due to different thermal expansion and contraction of pipeline and equipment, and support and stabilize pipelines near the equipment. They are especially suitable for thermal medium transmission pipelines connecting to equipment.

Dual temperature supports are dual high efficiency energy saving pipe support products that adopt core dual temperature structural design. Through temperature operating condition analysis (e.g. -165℃ to 280℃), in combination with pipeline thermal insulation thickness and climatic conditions, dual temperature pipe supports meeting engineering and process design requirements have been designed and manufactured, improving qualified product output rate.

Standard pipe supports include various types of supports and hangers used for horizontal straight pipe, horizontal bent pipe, vertical straight pipe, and vertical bent pipe. In terms of welding, they include welded type, pipe clamp type, and lined protection type.

Standard pipe supports have pipe diameter range of DN15~DN3000 and applicable load range of 5000~5200000N.

Damper is a vibration control device sensitive to speed. Damper piston movement is controlled by damping medium and valve, to suppress vibration of pipeline or equipment due to periodic or impact load, thereby protecting pipelines or suppressing vibration.

Travel range: 0~500mm; load range; 0~500KN; blocking speed: 2~6mm/s
