Investment Casting 150LB thread pipe fittings are included with ISO 4144 standard and SP114 Standard.
Our normal design is according to ISO4144 standard, compare with the SP114 standard, this design is the light type and it also could instead of SP112 sometimes.
Normal with Elbow, Tee, Hex Nipple, Socket Banded, Cap, Plug, Union, Bushing etc.
This kind of Pipe Fitings are produce from seamless pipes directly with SCH20, SCH40,SCH80 etc.
Normal Design with Coupling (FF), Barrel Nipple(MM), Welding Nipple (Toe Nipple), Round Hose Nipple Male Thread, Round Hose Nipple Welded etc.
High-pressure fittings always with Thread Ends(NPT/BSP) and Socket Welded Ends (SW).
According to ASME B16.11-2005 Standard, it is used in high-pressure environments, always in forged type.
Pressure rating as below:
Thread Ends: 2000LBS, 3000LBS, 6000LBS.
Socket Welded Ends: 3000LBS, 6000LBS, 9000LBS.
Including with Elbow, Tee, Coupling, Half Coupling, Cap, Plug, Bushing, Union, Out-let, Swage Nipple, Bull Plug, Reducer Nesert and Hex, Nipple, Street Elbow, Boss etc.
A buttweld fitting is a weldable pipe fitting that allows for change of direction of flow, branching off, reducing pipe size, or attaching auxiliary equipment. And it is in accordance with ANSI / ASME B16.9.
The surface treament always with sandblasting, Sand Rolling or pickling.
Including with 90 Degree Elbow BW, 45 Degree Elbow BW, Tee BW, Concentric Reducer BW, Eccentric BW etc.
Pipe fitting is the general name of the parts and components in the pipeline system that plays the role of connection, control, direction change, diverting, and sealing.
Steel pipe fittings are all pressure fittings. The different processing technology is divided into four categories, namely butt welding pipe fittings (with welded and seamless pipe welded), socket welding and threaded pipe fittings, and flange pipe fittings.
Pipe fittings of the small size are generally in one plastic bag.
Bigger size with Individual plastic bag packaging then put into cartons.
For some lower price items, Each carton with a big plastic bag, and the products are placed directly in the carton to solve the cost.
Color Marks & Color Boxes are also acceptable, and we have a success expensive about it.
Regarding Stainless Steel 304 material: In China’s local market, there is a different quality level of materials.
Such as stainless steel 304 standard is with at least 8 Nickel and 18 Cr. However, not all named 304 materials with standard chemical element composition. Few suppliers want to reduce the raw material cost; sometimes, they will choose maybe 7.5-7.8 Nickel or 8 Nickel with 17 Cr.
For all stainless steel products, no matter pipe fittings or ball valves, unit weight is the most important factor affecting prices. Clients who purchase from China for the first time will always be puzzled by this issue.- Why looks same products, has so many different prices. Not just 2 or 3 different prices, even each factory has a different price level.
This is because of unit weight, such as the wall thickness, length, etc.
Normally for small size (1/8″ to 3/4″), most the manufacture chooses tapping machines instead of CNC machine.
The difference between Tapping machined thread and CNC machined thread.
