4130 Pipes and Pipe Fittings

This low alloy steel containing nominally 0.3% carbon, 1% chromium and 0.2% molybdenum is used widely in oil patch applications. It is similar to 4140 which has a higher carbon level giving 4130 improved weldability in comparison to 4140, though this is achieved at the expense of through thickness strength. The hardenability limitations of this grade (depth to which it will harden / obtain the specified mechanical properties after heat treatment) must always be taken into account when designing and selecting equipment.

API Flanges

We 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.

API Studed Blocks

Flanged studded crosses and tees are available from 2” through to 6” with pressure ratings of 5,000 psi and 10,000 psi in AISI 4130 material.

Hub & Clump Connector

The 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

A full range of Hammer lug unions are available upon request from threaded Fig 200 unions through to Butt Weld Fig 2202 unions and are briefly explained as follows:

Threaded Unions

We offer various sizes of API Line Pipe Threaded Unions. The Threads are gauged with calibrated working API gauges, which are inspected regularly with API master gauges.

Butt Weld Unions

Hammer Lug Unions are available in all Fig. numbers as Butt Weld Unions as an alternative to the standard API threaded end. We mostly specialise in the highpressure unions described below. When ordering please state the required pipe schedule.

Hammer Lug Unions are available in Hydrogen Sulphide trim (Sour Gas H2S) with either Threaded or Butt weld ends. Sour Gas Unions are manufactured in accordance with NACE Standard MR-01-75. For ease of identification Sour Gas Unions are painted green.

Figure 1002

Recommended Service for the 1002 are Cementing, testing, and choke-and-kill lines with 10,000 psi (690bar) cold working pressure on 4" sizes and 7,500 psi (517 bar) cold working pressures on 5" and 6" sizes. The main features of these unions are that they have a replaceable lip type primary seal, which protects the secondary metal to metal seal, and minimises the flow turbulence. Both Butt-weld and Threaded connections are available. The Unions are also available for sour gas service: 7,500 psi (517 bar) cold working pressure.

Figure 1502

Recommended Service for the 1502 are Cementing, testing, and choke-and-kill lines with 15,000 psi (1034bar) cold working pressure. The main features of these unions are that they have a replaceable lip type primary seal, that protects the secondary metal to metal seal, and minimises the flow turbulence. Both Butt-weld and Threaded connections are available. The Unions are also available for sour gas service: 10,000 psi (690 bar) cold working pressure, butt-weld configurations only.

Figure 2002

Recommended Service for the 2002 are Cementing, testing, and choke-and-kill lines with 20,000 psi (1380bar) cold working pressure. The main features of these unions are that they have a replaceable lip type primary seal, that protects the secondary metal to metal seal, and minimises the flow turbulence, Butt-weld connections only.

Full Flow High Pressure Manifold Fittings are manufactured from wrought iron steel. Crosses and Tees are closed die forges to ensure they have a correct grain flow, high integrity and uniform shape. Both 45° and 90° elbows are produced from hollow or tubular bars, hot formed on purpose made bending machines or forged in closed dies. Full ranges of fittings from 2" to 6" are available with standard pressure ratings of 5,000 psi and 10,000 psi.

Long Radius Elbows & Fittings

Elbows have been forged and not welded to ensure that the end user obtains maximum results from the equipment. The following features of Oilquip fittings enable them to be categorised in the highest standard of high-pressure equipment.

• 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.
• Fully pressure tested and certified.
• Full material tractability.

High Pressure Manifold Fittings, Wrought Steel Fittings

We offer a complete range of couplings including high pressure quick disconnect self healing couplings, in numerous materials of stainless steel 316L and alloy 400. Hose couplings are available ex-stock both one and two piece forms, in all threads. In addition any other couplings can be manufactured to your requirement upon request .

We provide a range of fire rated control hoses with male sub & wing nut selfsealing couplings. These are also avaiable with SAE or swivel flange connections. Quality Assurance is in accordance with DIN to the standard 50049.3.1.B. We can offer proof tests of up to 30,000 PSI, and burst test of up to 60,000 PSI.

All rotary and vibrator hoses are manufactured to API Spec.7.K.
The range of hoses covers the complete Oil Industry:

• Oil exploration
• Oil production
• Oil transportation
• Oil refinery
• Oil field constructio

Hoses with internal stainless steel stripwound tubes for the transportation of oil, oil-gas, gas, water, suitable for vacuum service can be designed for combined functions which can be used in the following areas of the Offshore theatre of operations.

Flowlines (acc. To API RP 17 - B bonded type) - rises - production test lines - export lines - jumper hoses, spool pieces and tie in hoses - Hydraulic pile driving hoses in long length - burner hoses - well test lines - subsea crude oil hoses.

Choke & Kill Hoses

We can provide an elastormeric flexible hoseline, which is not prone to the so-called cold flow or creep, which is inevitable with thermoplastic tube materials. The hoseline can be uniformly bent in any direction, thus meaning it can be transported and moved with the greatest of ease.
Apart from the pressure resistant lining, the high strength steel cable reinforcements and cover, there are no other special constructional elements used. The cover can be normal, flame resistant or externally armoured with and interlock stainless steel tube.

Sizes range from 2" to 4" hose ID with working pressures of 5,000 psi and 10,000 psi.

The through conduit gate valve has been developed to satisfy the need for a high quality, high specification valve which is reliable and reasonably priced. Oilquip gate valves make full use of modern materials and manufacturing techniques. The valve is robust, easy to maintain, conforms to international Design requirements and Quality Assurance programmes.

The gate valve conforms to all aspects stated in the API.6A Standard. Manufacture of the valve takes place in a Plant that is regularly audited by Third Party Auditing Bureaux to ensure the API.Q1 and ISO9001 are fully maintained.

The initial cost of this valve is very competitive, but the longer term saving resulting from robustness and low cost of spares makes it the most affective valve on the market today.
