Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Taiyuan Huaxin Cheng electromechanical equipment spiral welded pipe for you to resolve common defects in how to detect the use of spiral welded austenitic spiral welded pipe when the defect detection equipment, when insulation is damaged or can have rain infiltrated the site, note that soaked detection flat head machine to detect stress corrosion cracking or pitting and other shortcomings. However, detection of magnetic particle or soaked steel outer appearance can only be detected flat head chamfering machine, internal appearance of the shortcomings of the powerless. The appearance of spiral welded pipe mill testing, especially crack type defects detected, it is necessary to carry through ultrasonic testing.

Taiyuan Huaxin Cheng electromechanical you resolve spiral welded pipe mill precautions spiral welded pipe mill stainless steel MIG welding points and precautions: 1. Using flat characteristic welding power supply, reverse polarity (wire connected to positive) 2. General use of pure argon dc gas (purity of 99.99%) or Ar + 2% O2, the flow rate to 20 ~ 25L / min is appropriate. 3. The length of the arc, MIG welded stainless steel pipe flat head machine, generally in the jet down conditions for transition welding, arc voltage to be adjusted to the extent of 4 ~ 6mm. 4. windbreak. MIG welding susceptible to wind, and sometimes the breeze and blowholes, spiral welded pipe mill so the wind speed at 0.5m / sec over the place, should take precautionary flathead machine price _ Huaxin Cheng electromechanical (certified) _ Jiangsu with the first machine by Taiyuan Huaxin Cheng Electrical Equipment Co. provided.
