Bulk Figure 602/1002/1502 Hammer Union Seals Manufacturer for Oilfield Applications

Introduction to High-Performance Hammer Union Seals

---

Hammer union lip seals are replacement components for the specified union manufacturer, figure, nominal size and seal groove. Match seal geometry, compound and backup arrangement to the actual assembly. The complete union’s documentation determines pressure and service acceptance; the seal alone does not establish a connection rating.

SHQN / Royal Way supplies molded rubber seals within an ISO 9001 quality management system. Confirm the original component reference or drawing for each union; matching figure numbers alone does not establish interchangeability between manufacturers.

Technical Specifications & Working Pressure

The existing size list includes nominal 1-, 2-, 3- and 4-inch references. Confirm the requested size and figure combination against the actual union. The legacy table below lists pressure classes for identification only; verify the complete union manufacturer rating, service class and operating limits before selection.

Material Comparison: Choosing the Right Elastomer

---

The existing material options include NBR, FKM and HNBR. Select the supplied compound grade against actual fluid formulation, gas exposure, temperature and pressure cycles. Material-family descriptions do not qualify a seal for every oilfield duty.

1. Nitrile (NBR/Buna-N)

• Temperature Range: Confirm supplied compound continuous and peak limits for the stated service.

• Material Review: Review NBR grade against oil, water, additives and wear duty.

• Advantage: Specify abrasion and mechanical-property requirements for the selected NBR grade.

2. FKM / Fluorocarbon

• Temperature Range: Confirm supplied compound continuous and peak limits for the stated service.

• Material Review: Review FKM grade against fluid formulation and temperature.

• Advantage: Specify the FKM grade for the actual chemical formulation, temperature and exposure duration.

3. HNBR (Hydrogenated Nitrile)

• Temperature Range: Confirm supplied compound continuous and peak limits for the stated service.

• Material Review: Review HNBR grade for mechanical duty; H2S/CO2 exposure requires qualification.

• Advantage: Agree mechanical-property and wear requirements for the selected HNBR grade.

Key Features of SHQN Hammer Union Seals

---

• Replacement Fit: Verify manufacturer, figure, nominal size, groove dimensions and seal component reference. Compare the original seal profile and backup arrangement for that manufacturer and figure.

• Lip Profile: Match the specified profile and installation orientation to the union drawing. Inspect the mating surfaces and follow the manufacturer’s assembly and acceptance procedure.

• Bulk Orders: Confirm quantities separately for each figure, size, compound and backup configuration, together with availability and lead time.

• Quality Management: ISO 9001 supports manufacturing processes. Agree dimensional inspection and compound documentation against the original seal drawing. Specify drawing tolerances and required inspection documents on each order line.

Oilfield Applications

---

Our seals are widely used in the following energy sectors:

• Well Completion & Stimulation: Hydraulic fracturing and acidizing.

• Drilling Operations: Mud pump manifolds and flow lines.

• Midstream Transport: Temporary pipework and manifold trailers.

• Offshore & Onshore Rigs: Cementing units and high-pressure gas lines.

Frequently Asked Questions (FAQ)

---

Q1: How do I confirm a Weco-style replacement?
Provide the actual union manufacturer, figure, nominal size and seal part reference or drawing. Check the groove and backup arrangement before ordering; a shared figure label does not prove cross-brand fit.

Q2: How is a mixed bulk order quoted?
List each figure and size as a separate line item, with compound grade, backup arrangement and quantity. Confirm stock and production lead time for each configuration.

Q3: How is sour-service duty reviewed?
Provide H2S and CO2 composition, pressure, temperature and decompression conditions. Confirm the particular compound, metal specification and complete-union acceptance; polymer family or ring color alone does not establish qualification.

Bulk Hammer Union Lip Seals: Keep Figure and Size Separate

For a mixed shipment, label each seal group with the union manufacturer, figure, nominal size, component reference, compound grade and backup configuration. Record quantity and batch identification separately for each line item. Match the packing list to the original seal drawing before installation. Color is an identification aid only when defined by the supplier specification; it does not establish polymer grade or pressure class.
