Yesterday, a customer engaged in laser cutting machine consulted S&A: "Why is the water flow of water chiller insufficient?"
S&A water chiller: "Hello, what is the model? What is the bar code?"
It was found out through communication that what the customer used was not TEYU (S&A) water chiller. Water chillers of various brands were different in construction, so S&A failed to provide a specific solution for such laser customer.
But there were two different cases for the insufficient water flow of TEYU (S&A) water chiller.
Firstly, the insufficient water flow occurring at the beginning was caused by the unmatched pump selection. Some lasers have strict requirements on water flow and lift or the cooling pipe is too long and too thin, so a pump of larger power shall be provided.
Secondly, the insufficient water flow occurring suddenly in the normal use process may be caused by pump failure or pipe blockage. In this case, S&A suggested customers to take out the pipe and opening the pipe with air compressor gun, and then connect the pipe to observe whether water chiller can run normally. If the water chiller runs normally, it is caused by pipe blockage; if the water flow is still insufficient, it is caused by pump failure, and a new pump shall be provided.
Thank you so much for your support and trust in S&A. All S&A water chillers have passed the certification of ISO, CE, RoHS and REACH, and the warranty period has been extended to 2 years.

Coupling
Tubing and casing couplings are the joining of two short length pipe, mainly used for the connection and repair of oil pipe and downhole tools
Tubing and couplings thread types : Non-upset thread(NU), External- upset thread(EU);
Casing and couplings thread types: Long-round thread(LC), Short-round thread(SC), buttress thread(BC)
Grade: K55,J55,N80-1,N80Q,L80-1,P110,etc.
Pup joint
Tubing and casing pup joints are machined according to the latest version of API SPEC 5CT. The steel grade includes J55,K55,N80-1,N80Q,L80-1,P110,etc. There are two types of thread widely used in tubing pup joint namely Non-upset thread(NU), External- upset thread(EU);
Casing and couplings thread types: Long-round thread(LC), Short-round thread(SC), buttress thread(BC).
Our testing and inspection method system is complete, using a whole set of thread instrument to inspect taper, pitch, tooth, height, tooth type,etc. The products have passed the identification of china petroleum pipeline. Quality supervision ,inspection and testing center and gained the unanimous praise from the customers.
