Henan Sheng He Pipe Industry Co., Ltd., have an experience spanning for over ten years, producing and supplying best-in-class products, minimize cost by getting manufacturing processes under one roof and delivering consignments on a daily basis only because of a diligent and dedicated team. We are manufacturers, suppliers and exporters of Butt Weld End Cap.
Butt Weld pipe fittings production process
Buttweld Fittings manufacturing process includes a series of steps like Annealing, Straightening, Pickling & Passivation and Polishing.
Pipe End Caps, also known as Pipe Caps, suggest their function through stheir name: they act as a seal to the end of a pipe. Their primary function is to waterproof piping networks in addition to resisting chemicals, moisture and weather. Our end caps have pressure releasing abilities and flexible.

General notes..
- Dimensions are in millimeters unless otherwise indicated.
- Wall thickness (t) must be specified by customer.
- The shape shall be ellipsoidal and shall conform to the requirements given in the ASME Boiler and Pressure Vessel Code.
- Length (H) applies for thickness not exceeding that given in column “Wall Thickness” for Length, H.
- Length (H1) applies for thickness greater than that given in column “Wall Thickness” for NPS 24 and smaller. For NPS 26 and larger, length H1 shall be by agreement between the manufacturerand purchaser.

Note..
MSS SP-43 only covers stainless steel buttweld fittings made for use with Schedule 5S and 10S pipe and Stub Ends suitable for use with Schedule 40S pipe, as defined in ASME B36.19. The dimensions and dimensional tolerances defined in MSS SP-43 are substantially the same as those in ASME B16.9 specifications from NPS 1/2 – NPS 24. Except with regard to the outside diameter at the bevel.
