Our quotation for plate heat exchanger, is it really expensive?

Low prices in our daily life, is a very normal thing; But as the old saying goes: a point of price a point of goods, every family said their products good, low price, the product really can be good to what extent ah? This article USES a plate heat exchangerto illustrate the relationship between price and quality.

As we all know, every country has different requirements on quality, which is why there are European CE quality management system, American ASME quality management system and Chinese ISO quality management system. From the perspective of heat exchanger industry alone, CE certification in Europe and ASME certification in the United States are very difficult to obtain, which have high requirements on the quality inspection, processing technology and raw materials of products in the production process.

Every part of a plate heat exchanger is very important. No matter it is the plate, strip or frame, the first thing to look at is the raw material. In the case of the plates, the raw materials used by Alfa Laval come from the same supplier? Or a domestic company production of stainless steel plate, plate thickness, trace element content, flatness and so on are different, if the former price is high, let you choose one of the two you will choose which? When designing and selecting, do you find that the heat exchange area given by different manufacturers varies greatly under the same working condition? Some manufacturers to quote high false heat area, clearly 10 square meters, 10 board can solve the problem, must be 15 square meters, 20 board is willing to fix, the price is high, but also a waste of money; Also, what type selection software is used?Engineer selection? How many years of design experience? These are all reasons for the price gap. In terms of processing technology, many people only value the quality of the sheet and strip, what about the frame? I don't care. Frame is used to bear plate and tape, meaning is also very big, not only its own weight, its load-bearing force is also very important: 1. Frame painting only has six and a difference in, 2.When it comes time to disassemble equipment, repair and reassemble it, you'll know how much effort the frame saves.

Qingdao Switzerland put with Alfa Laval raw materials supply factory always maintain good relations of cooperation, and 13 years in a row heat exchanger supply contract with foreign brands, to European production process, strict quality inspection system heat exchanger with Alfa Laval international synchronized upgrade production technology, just a frame painting process several working procedure more than other companies and all of this is the customer as the center. In the production process of uneven quality heat exchanger industry, we can not be cheated is not ~ next time to purchase, do not blindly seek low prices, see the product understanding the production process you will find that the price is really not high ~

There is no uniform price in the market,and you can always find one cheaper than me. But in addition to genuine, quality assurance,I can't give you anything,Ruipute, Qingdao.
