high & low swivel joints
Senoil is focus on high pressure fluid product all the time for years. And working pressure is from 2,000psi to 15,000psi. Sometimes, we forget that we also can produce low pressure swivel joints which bore size is a little bigger, from 8″ to 12″. For low pressure swivel joints or straight pipe, we normally weld union or flange to seamless pipe or elbow. For weld process, we do WPS/PQR. For some serious working condition, we do 100% RT to inspect weld result. For swivel style, we always follow FMC. Below is some brief drawing show difference between high and low pressure swivel joints.
Geothermal Wellhead Program
Oil price is rising recently, and we get some tenders for geothermal wellhead from different countries. Geothermal wellhead is one kind of special wellhead which is used for steam. Wellhead program is simple, but it refers to different standard. Normally, wellhead is designed and fabricated according to API 6A. But for geothermal wellhead, the master valve is normally fabricated to API 6D.
Maybe some friends will ask how 6A flange can connect with 6D flange. If you compare with ASME standard, you will find that for low pressure connection, 6A and 6D adopt flange size from ASME. So 6D mater valve can connect with 6A Casing house.
Below is two G.A drawing which will show you more and clearly.
Chemical Injection Pump Operation Manual
Chemical InjectionPump is used to inject chemicals to well line upstream of choke manifold. Below is our standard product operation manual.
FC type gate valve operation manual
FC type gate valves are our common product supplied to many countries. So we hope our customer can find operation manual in our blog. And below is one manual for standard product.
downhole cable protector
After this post, maybe many friends will ask why you write post about protectors as this product is not your key product. Although it is not high pressure pipeline product, not used on well testing process, but it have some connection with wellhead. The most important reason is that one of my customers who run casting protector business for many years doesn’t know stamping cable protector. So I thought I need to put the post ahead.
Expanding slab gate valve and single slab gate valve
In our production scope, API 6A gate valve is popular used on pipeline, wellhead, flowhead, choke manifold, and etc.
Our connection to Check valve
It seems that Check valve is a simple valve in our production line which is structure is easier than gate valve, ball valve, global valve, plug valve and etc. but why we still want to write a post for check valves. Because I feel that there is an interesting knowledge journey to check valve.
Hammer union
Hammer union is a kind of quick connection that can connect pipe or fittings by copper hammer. The most popular brand is FMC weco wing union which divided into many figures. But for our well testing job or high pressure well service, we normally use FIG206, FIG602, FIG1002, FIG 1502, FIG2202. The front 1 or 2 number normally means pressure, last one means type. For example, FIG 1502, the working pressure is 15,000psi, and connection type is 02. The highest class is FIG 2202, which is work under 15,000psi in sour service.
