FD-LOK specializes in producing high pressure pipe fittings

FD-LOK Manufacturing specializes in producing high pressure pipe fittings and flowline products for the upstream oil industry. FD-LOK's product list includes 1½ inch and above high pressure flow line components including threaded and integral cross, tee, fittings. We make high pressure pipe fittings, 37° flared tube fittings, double ferrule fittings.
All manufactured high pressure pipe fittings are made from certified materials and are identified at the time of manufacture. FD-LOK manufacturing provides traceability of materials used during and after the manufacturing process. FD-LOK Manufacturing produces parts that are interchangeable with other major manufacturers.

FD-LOK High Pressure pipes fittings are widely used

High pressure pipe fittings satisfy the increasing demand for American and European standard pipes and fittings for Plumbing applications that demand high operating pressure, high levels of toughness, chemical and resistance along with cost effective.
FD-LOK High Pressure pipes fittings are widely used in:
Distribution of cold water under pressure.
Air conditioning drain systems.
Piping networks for swimming pools facilities & rainwater utilization.
Cold fluids circulation in industries.
Transport of chemicals and corrosive fluids in industries.

High Pressure components use a coned-and-threaded connection

High Pressure needle valves, fittings, line filters, check valves, safety heads, rupture discs, anti-vibration gland assemblies, tubing and nipples are engineered to the highest standards of repeatable quality.
High Pressure components use a coned-and-threaded connection which accommodates the high temperatures and pressures common in these applications. High Pressure valves are available in various tubing sizes and with body designs to satisfy widely varied requirements. A line of fittings is available to facilitate adapting to Taper Seal, Medium Pressure, or other High Pressure threaded pipe systems. Stainless steel is recommended for marine applications, chemical processing and other harsh operating conditions.

High Pressure Equipment Company

High Pressure Equipment Company has developed a line of High Pressure products to assure safe and easy plumbing. These needle valves, fittings, line filters, check valves, safety heads, rupture discs, anti-vibration gland assemblies, tubing and nipples are engineered to the highest standards of repeatable quality. The reliable performance of these products has made one of the world’s leading suppliers of elevated pressure components.

Pipe o-ring check valves provide high quality directional

Pipe o-ring check valves provide high quality directional flow control and bubble tight shutoff for liquids and gases. These check valves are not to be used as a relief device. The opening pressure of the o-ring check valves is approximately 10 psi.
Pipe ball check valves prevent reverse flow where bubble tight shut off is not mandatory. These check valves are designed to operate to 660°F. These check valves are not to be used as a relief device. The opening pressure of the pipe ball check valves is approximately 10 psi.
This design increases the stainless steel filter area as much as 6 times the area of the disc type filter, and will permit higher flow rates with a lower pressure drop, and longer intervals between element changes.

Analytical high pressure elbow high-pressure pipe production process

Elbow production process is FD-LOK socket weld fittings a first polygonal cross-section or a polygonal ring shell closed at both ends of the multi-row fan shell, inside elbow washed over the pressure medium within the pressure applied, including action under pressure from the polygonal cross-section gradually turned round, eventually becoming a circular ring shell, this process ideally suited to the high-pressure method and stamping elbow elbow in diameter than the inner diameter larger than any standard 1.5 large elbow, is to create a large national standard elbow manufacturing. Elbow high pressure pipeline system applicable to oil, gas, chemicals, utilities, construction and boiler industry. Without tube for raw materials, equipment and metric pipe fittings can save tooling costs and arbitrarily large diameter and wall thickness can be obtained relatively thin GB elbow. Elbow can shorten the manufacturing cycle, the production cost is greatly reduced. Does not require any special equipment, it is particularly suitable for on-site processing of large GB elbow. Blank or developable surface is flat, so simple cutting, easy to ensure accuracy, easy assembly and welding. While high pressure elbow high pressure generally applicable to oil, gas, aerospace, shipbuilding, chemicals, utilities, fire protection, construction and other industries boiler piping series.

Stainless steel needle selection principles

1 , the pipeline system and cryogenic medium , should use plus low bonnet needle valve .
2 , the pipeline system FCCU refinery unit , optional needle valve lift rod .
3 , fixtures and piping systems , such as acid-base chemical systems in corrosive media , should use austenitic stainless steel , Teflon seat ring in  Stainless steel needle valves  .
4 , metallurgical systems, piping systems or devices on the power system , petrochemical plants , urban heating systems in high-temperature medium , the choice of metal to metal seal needle valve .
5, the need for flow regulation , the choice of the worm gear , pneumatic or electric adjustment with a V -shaped opening needle valve .
6 , transmission mains oil, natural gas , it is necessary to clean the pipeline , buried in the ground and the need , use full bore , all-welded construction needle valve ; buried in the ground , choose full bore welded or flanged connections the ball valve.
7 , pipelines and storage facilities for refined oil products , the choice of needle valve flange connection .
8 , city gas and natural gas pipeline , the choice of the needle valve flange and the threaded connection .
9 , metallurgical oxygen pipeline system , should use rigorous degreasing treatment , needle valve flange connection .
