Anhui Tianda independent research and development of four station hydraulic press for heat exchange tube has been put into use

Anhui Tianda OilPipe Company Limited has a number of hydrostatic test equipments with variousdiameter and pressure, and the highest test pressure can reach 160 MPa.Inallusion to characteristics of small diameter, fixed length, hydrostatic testpressure not high for heat exchange tube of pressure vessel, the company units some scientific research, togetherdo independent research and development for four stationhydrostatic test unit and tests specifically for thehydrostatic test of heat exchange tube. The so-called four station hydraulic press, refers to the test which can do hydraulic test of four steel pipessimultaneously. Compared to the traditionaltest which only can do hydraulic test for steel pipe one by one, the efficiencyincreased four times by using the new one. This machine adopts double beamstructure, turn in and out of the material through the chain lateral movement.Each work cycle can test four steel pipes. Pressuretesting process is monitored and controlled by the 'industrial computer +PLC' by set of system parameters,pressure testing curve display, running state display, storing and printing,etc,.It is the domestic first time realize that water pressure curves of four station display at the same time. Adopt externalsmall gap typeradial seal type, the service life of seal is ≥2000 times. It has many advantages such as simple structure, safety, environmentalprotection, stable and reliable, etc..

Heat exchange tubeis a feature products of our company, with high market popularity, high marketshare and high product quality requirements.Regarding to two sizes( ∮19 and ∮25) of small heatexchange tube, our company delivery about 20000 tons per year, including 10 # and 20 # carbon steel pipe, 08Cr2AlMoanti- Cl corrosion pipe, 09CrAlMo for corrosion resistance to seawater. etc.. Meetthe standards of GB150.2-2011《pressure vesselmaterials》, NB/T 47019-2011《theboiler tubes for heat exchanger order technical conditions 》, theGB9948-2013 《seamless steel tube used in oil cracking》,GB5310-2008《Seamless steel tubes and pipes forhigh pressure boile》, GB3087-2008《Seamless steel tubes and pipes forlow mediumpressure boiler》, GB6479-2013《Seamless steel tubes for high-pressure for chemicalfertilizer equipments》, aswell as the ASME, ASTM, EN, DIN, BS, NF, JIS standard, single length can be upto 30 meters. So far, leak phenomenon has not appeared during the use of customers, our company is the only domestic manufacturer which canindicate if there is a leakage, the fine of ￥10000RMB in the contract. Putting into use of four station hydraulic press for heatexchange tube greatly improves delivery speed of the heat exchange tube, gettinghigh praise from the customers.
