Q1: What is the Warranty for the solenoid valves? A1:  For the valves,we have one and half year warranty.If any quality problems on our side occured in this period ,we will make  replacement.  Q2:: What is NO and NC? A2: NO stands for normally open, that is , valve keeps open without power.If connect  it with power, the valve will get closed.NC   stands for normally closed,that is valve keeps closed without power.If connect  it with power, the valve will get open.  Q.3: What is the assembly way of solenoid valves? A.3  we suggest to make horizontal installation to enlarge life time,but it can be vertical installation if have special request.  Q4:Is there cheap shipping cost to import to our country? A4: For small order,express will be best.And for bulk order,sea ship way is best but take much time. For urgent orders,we suggest to ship by air.  Q5:Can we make customized product? A5: Yes, we are good at making customized products.More than 30% of our products are customized products. We have successfully customized for customer from various fields from USA,Norway.Australia, Germany ect.
ERW PIPE is high-frequency Electrical Resistance Welded Steel Pipe,The hot rolled coil is formed by forming machine,use the skin effect and proximity effect of high frequency current,make the edge of the tube heat and melted,weld it under the action of the extrusion roller to achieve to produce .
Production OD:21.3-508mm
Nominal Wall Thickness:3.2-15.9mm
Pipe Length: 8-12.5m
Steel Grade:API Spec 5 L A,B,X42-X80
API Spec.5L, ISO3183, China GB/T9711 etc. and the additional technical speciï¬cation required by the end user.
The ERW pipe is widely used in long distance pipeline project for transmission of oil, natural gas, water, coal gas, mineral slurry etc., and also is applied in engineering such as chemical industry, electric power, irrigation, construction and piling etc.
