Heat exchanger


Briefintroduction

  In 1984, our company General manager Zhang Zhiqiang participated in the researchon the first domestic graphite modified PP tubular heat exchanger as the representativeof the current factory and achieved the success, which filled up the domesticblank. Hereafter, the products were widely applied in the industries likechemical industry, pharmacy, metallurgy and food etc.

   Yili graphite modified PP series tubular heatexchanger shell is the anti-corrosion heat exchanger with the entire plasticstructure which is made of entire strengthened PP tubes, pure PP plates ormodified PP plates and graphite PP heat exchanging pipes after the secondprocessing.

Theproduct is fixed tube sheet and shell structure. The heat exchange tube of YiliSPGH series heat exchanger is the specialized graphite modified PP slender tubewith thin wall, and the graphite content is up to 50% (weight ratio).

   The products keep the advantages of the PP device with its corrosion resistance,high strength with light weight as well as not easy to deposit etc. At the sametime, it largely increases the properties of heat transfer. The total heattransfer coefficient of the device reaches 250400KCal/m h.


Model description

 

The characteristics

1.      Excellent corrosion resistance which can resistalmost all the inorganic medium and most organic solvent.

2.      Both tube pass and shell pass can transfer thecorrosive medium.

3.      Good and stable heat transfer.

4.      Not easy to deposit and non-toxicity.

5.      Light weight, small-size volume, and convenientinstallment and maintenance.

6.      Economical price and cost.


Application range

   Allowable temperature: -2080   0120(PP)

   Allowable pressure (normal temperature): shellpass≤0.3Mpa   Piping pass≤±0.2Mpa

   Allowable medium: please take the corrosionproperty of PP as a reference when there is no information or there is otherspecial requirement, it can take the experiment according to GB11547-89.

Somedifference you should know

I.         Qualification

and are authorized. The enterprises without thecertificate are not allowed to manufacture the relative products and thepurchase users will also take a risk on it.

II.      Design capability

With25 years of the safety production experience, we can guarantee the design ofeach device in compliance with the industrial standard, even exceed it, and itis proved to be safe after the practical use.

III.    Materials selection

The products are certainly worth it and thesafety is the utmost.

IV.    The processing technology

When most of the similar manufacturers relied onthe manual welding processing device, we adopted to combine different weldingtechnologies like German hot melted butt-joint welding and extruding weldingetc. The welding strength was improved. Meanwhile, it put an end to thedisorder emotion and empiricism influence onthe device quality.
