Do you need API Connections, API and ANSI pipe fittings, or fittings that meet any other standard for your next project? Then get in touch. We have a large selection of API Connections & Alloy Steel AISI 4130 Fittings to meet your needs. Plus, we can ship globally with a fast turn-around time.

When you buy API Connections, you want to be confident that it will perform as you expect. That’s why standardization systems are so important. They let us know that what we’re getting is what we think we’re getting, and that it won’t let us down. This is especially crucial when the consequences of a product failing are dire–like in an engineering project. The piping industry relies on standards. The API Connections are manufactured to sustain very high pressure and product warranty.

All materials supplied by MD Exports LLP will meet or exceed ASTM, ASME, ANSI and/or API standards, per your required specifications including full documentation.

API Flanges

MD Exports LLP offer a large range of API 6A and ANSI forged swivel flanges, Blind flanges, slip-on flanges and weld-neck flanges in 4130 carbon steel, to suit 2” to 6” nominal bore XXS pipe with pressure rating below. The API 6A specification requires a rigorous and unique quality system including stringent dimensional and NDT control. The application of an API monogram is that you, the client will be guaranteed of total compliance with the API specifications.

Hub & Clamp Connector

The MD Exports LLP connector is a compact mechanical joint consisting of four basic elements:- hubs, seal ring, clamps and bolting. During assembly the hubs are pulled together under the twin wedge action of the clamp segments, the sealing action is improved due to internal pressure. Each connector requires only four bolts, which includes a 100% safety/redundancy factor. The ability of the clamp connector to withstand severe bending without leakage or periodic re-tightening, has been recognised for many years in the Offshore Industry. All materials are AISI 4130- carbon steel and meet the requirements of NACE with the following pressure ratings. The particular advantage of the connector is its ability to be disconnected quickly and avoid ‘hot work’ on site.

API Connections features:

  • Eliminates post weld heat treatment requirements that restrict the material’s potential strength.
  • Have smooth round uninterrupted bores to minimise pressure drop and turbulence.
  • Inherently stronger.
  • End fittings machined integrally.
  • Do not require costly weld inspection.
  • API Connections with fully pressure tested and certified.
  • Full material tractability.

The Right Industrial API Connections for Your Project!

We manufacture API Connections which are mainly used for high pressure Applications like sour services, Low temperature, onshore offshore Drilling, Manifold Equipments and Rig Projects.

  • API Connections Packaging & Shipping

API Connections Packed

API Connections Packed

API Connections Packing: We focus on every procedure to assure quality, the package we usually take is pack API Connections with environmental poly bags, and then in free fumigation wooden cases or wooden palte. Also can accept customized package such as OEM by negotiation.

MD Exports LLP offers just about everything to meet your Fittings pack requirements. Lot of emphasis is placed on the packing and packaging . The API Connections are packed in wooden corrugated boxes foiled in plastic wraps and bubble wraps. Caps are made available to the ends on request of the buyer.

API Connections Marking: All alloy stel fittings are marked with size, cast number and specification. Or as per customer’s requirement;

Packing Type for Alloy Steel AISI 4130 Tee, Elbow, Cross, Reducers etc.

API Connections Inner packing

API Connections Outer packing

So, besides the fact that we can arrange freight transportation for you, we can before that: 

  • specifically mark parts or packages;
  • provide for a special packing according to what is required by the shipping method or by you.

We mark the API Connections as needed with the most suitable marking technique.

When packaging and packing, our experienced warehouse staff systematically takes the greatest precautions for your API Connections to be optimally protected during transportation. We pack the API Connections according to the appropriate method: strapped pallet, wooden crate, overseas packing (ISPM15).

AISI 4130 Alloy Steel (UNS G41300)

Integrating fittings into piping systems is a various important task. After all, it’s at the connections between pipes where the system is most susceptible to leaks and failure. As such, many pipe fitting connection methods require special training to be executed. From soldering, to threading to brazing, there are many types of connection methods. One of the most popular, however, is welding. To give you a brief idea of how it works, let’s look at how standards apply to industrial pipe fittings. API Connections standards give us information about how fittings were designed, how they were constructed, and how they can be expected to perform. Some of the characteristics that pipe fitting standards cover include:

  • Size
  • Pressure-temperature ratings
  • Design
  • Materials
  • Coatings
  • Marking
  • Threading
  • End connections
  • Dimensions and tolerances
  • Pattern taper

Types Of Industrial Pipe Fitting Standards

There are a number of organizations that specify pipe fitting standards. Some of the most well-known include:

  • ANSI: The American National Standards Institute
    This private, non-profit organization coordinates the U.S. voluntary standardization and conformity assessment system. ANSI’s ‘schedule numbers’ classify wall thicknesses for different pressures uses.
  • ASME: American Society For Mechanical Engineers
    ASME is one of the most respected organizations when it comes to developing standards and codes.
  • ASTM International: American Society for Testing And Materials
    One of the largest voluntary standards development organizations, ASTM develops and publishes voluntary standards on the basis of materials, products, systems and services. Its standards include pipes, tubes and fittings.

Grades shown in the above list with prefix letter E are normally made only by the basic electric furnace process. All others are normally manufactured by the basic open hearth or basic oxygen processes but may be manufactured by the basic electric furnace process with adjustments in phosphorus and sulphur.
